BEST BACKPACKING SLEEPING BAG OVERALL

The Western Mountaineering UltraLite is an ultra light and ultra premium backpacking sleeping bag that is our pick as the best overall choice.

What we love the most about this bag is its balance between weight, quality, versatility and comfort. It is rated to 20-degree and only weighs 17oz making it an excellent choice for fast and lite colder weather trips. The UltraLite’s horizontal baffle design allows you to move the feathers to the back of the bag, making it less warm for spring and mild summer conditions. 

The biggest downside of the UltraLite is its price tag. At $525, it’s one of the priciest bags on our list. However, if you’re a true backpacking junkie who wants an all around awesome bag, it might be a worthy investment. 

A close contender to the UltraLite is the Feathered Friends Hummingbird YF20 (and similar bags within their range). If you’re having trouble deciding, one feature we loved about the UltraLite that we didn’t find on others is the full goose down draft collar. This lets you bunker down and seal your body heat, a much appreciated feature on chilly nights.

BEST ULTRALIGHT SLEEPING BAG

The Feathered Friends Hummingbird UL 20 is a super light and packable three season sleeping bag. It’s our pick for the best ultralight backpacking sleeping bag.

What we loved the most about the Hummingbird is the conservative, even borderline generous temperature rating. This is not something we could say about a lot of other ultralight bags out there. The Hummingbird is stuffed with 950+ goose down which makes it extremely warm and light.

One drawback of the Hummingbird is the fit is pretty snug. If you’re a side sleeper or a bigger guy or gal, you might find the narrow dimensions claustrophobic. If you toss and turn a lot and would prefer a more spacious bag, check out the Feathered Friends Swallow and Swift. Another downside is since Feathered Friends is a cottage manufacturer, stock can sometimes be limited and wait times can be long. If you love the idea of owning a handmade sleeping bag that is tailored to your needs, be sure to order well ahead of your next trip.

The Hummingbird UL is in close competition with Western Mountaineering’s UltraLite. which is also featured on this list. While both are excellent choices for serious backpackers, the Hummingbird is 5 ounces lighter, making it a winner for those who are meticulous about cutting weight.

The Hummingbird UL is also available in a 30-degree version.

BEST FOR: A COZY AND WARM HOOD 

Let’s start our rundown of the best 20 degree sleeping bags with the Phase 20 from Marmot. The 850-fill power down insulation provides consistently good warmth for those chillier camping nights. The hood furthermore includes a very handy drawcord, allowing you to cinch it snugly around your head to lock in the heat. 

Marmot has also included an internal stash pocket to keep any items you need close at hand. For my part, I find it very useful to stash my phone at night if I’m listening to music and want to keep the cold air from draining the battery. The down defender treatment also helps keep any moisture from seeping in and wreaking havoc on your insulation. 

While Marmot has certainly produced a beautiful sleeping bag in the Phase 20, it seems they tripped themselves over the zipper. The most common drawback we’re seeing across the board is a small and weak zipper that perpetually snags. So keep this in mind, and remember to handle that zipper with care if you commit to this sleeping bag.

BEST FOR: MODULAR SLEEPING BAG    

Most of the grizzled hiking veterans out there have at least two sleeping bags, right? A light bag for warmer temps and a heavier one for the colder weather. Some folks will even have three or more bags! So how about a modular sleeping bag you can fine-tune to the temperature of your hiking adventures? Sounds amazing to us too, and that’s why The One Bag from The North Face made our list of the best 20 degree sleeping bags – even though it works for a range of temperatures. 

This bag comes with a synthetic outer layer that is rated to 40 degrees alone. Add in the down mid layer with the synthetic bottom for 20 degree temperatures. Or combine the down midlayer with the synthetic top and bottom for 5 degrees. All these layers do add more bulk than a strictly down sleeping bag, however. The complete system clocks in at well over 3lbs and only packs down to 17 liters. 

Bulk aside, this is still an excellent sleeping bag for those of you who don’t want to spend the money buying multiple sleeping bags for warm and chilly conditions. The One Bag allows you to consolidate down to a single sleeping for all your hiking trips, except extreme cold, and for a very reasonable price.

BEST FOR: HIKERS WHO WANT MORE SHOULDER ROOM

Don’t you hate trying to roll over in your sleeping bag and your shoulders seem to get wedged between the upper and lower layers? Us too, and that’s why the AlpinLite is among the best 20 degree sleeping bags. This bag is designed with you broad chested hikers in mind to make sure you can sleep in comfort on every single hiking trip. 

We’ve found the 63” to 65” shoulder girth to give just about everyone plenty of room to snuggle in and find that sweet spot for optimal sleeping. All other features of the AlpinLite are near identical to Western Mountaineering’s UltraLite sleeping bag. This bag is very comfortable due to its 850-fill down insulation nestled in a soft nylon shell. And it’s even manufactured in the U.S.A. 

As with most products from Western Mountaineering, the AlpinLite comes with quite the pricetag. But it’s premium build quality, comfortable materials, and very roomy design easily make this a worthwhile investment for you serious hikers out there.

BEST DOUBLE SLEEPING BAG

The Feathered Friends Spoonbill UL is a two-person sleeping bag for couples who want to lighten their load.

What we love the most about the Spoonbill UL is it gives couples the warmth and intimacy of being in the same bag without having to give up comfort. There are two hoods and two collars that can be adjusted and a zip on each side so you don’t have to worry about bothering your partner when you get in and out. Feathered Friends trimmed unnecessary insulation from the bottom part of the bag and the floor is made of a super lightweight Dyneema fabric. All of this results in a warm, lightweight and comfortable sleeping bag. 

One of the downsides of the Spoonbill is it’s not great for couples who want to cuddle because of its two separate hoods. Another consideration is its price tag is pretty crazy, however if you consider the price of two premium sleeping bags, it might be worthwhile. It also loses major points when it comes to versatility. If one of you decides to go on a solo trip, you’ll need a different bag.

If the price tag puts you off, check out the Big Agnes Sentinel 30. It is a much more affordable double bag option.

BEST FOR: BUDGET SYNTHETIC SLEEPING BAG 

Synthetic insulation has been slowly retreating from the backpacking realm for some time, but it’s still a viable option for a budget hiker. The Trestles Elite Eco 20 is therefore our top synthetic recommendation for not breaking the bank but still hitting that 20 degree rating. 

The proprietary HL-ElixR insulation resists moisture reasonably well, which is certainly a benefit in wet weather. It’s also plenty warm for the majority of your hiking adventures and is very comfortable to curl up in. The drawback to this synthetic insulation, however, is that it is heavier than down and won’t pack down as much for transport. 

But we can’t argue with such a low price, and we definitely feel that the Trestles Elite Eco 20 is a great entry-level sleeping bag. Perfect if you plan on camping only intermittently, or aren’t ready to make a major investment quite yet.

BEST FOR: BUDGET DOWN SLEEPING BAG OPTION 

Finally! A down sleeping bag that doesn’t leave our bank accounts in tears. The Kelty Cosmic 20 provides all the essentials we need in backpacking sleeping bag at a very reasonable price, earning it a place amongst the best 20 degree sleeping bags. 

The 600-fill power is definitely lower than most of the competition, but still manages to provide sufficient insulation in cooler temperatures. Kelty also includes a water repellent treatment to try and lockout as much moisture as possible and keep that down nice and fluffy. We’re also pleased with the external stash pocket to keep gear close, or store your favorite fuzzy sleeping socks when packing up in the morning. 

Keep in mind that the lower price of the Cosmic comes at the expense of build quality and materials. While certainly functional, it lacks the premium feel and durability of the competition. So if you’re liking the low budget Cosmic option, be sure to take care of it!

BEST FOR: LIGHTWEIGHT BACKPACKING 

If you’re always struggling with your sleeping bag’s bulk or weight, then we highly recommend you consider the Hyperion 20 from Therm-a-Rest. This incredible sleeping bag weighs in at only 1lb 6oz. We know blankets and quilts that weigh more than that! What’s more, the Hyperion packs down to only 3.7 liters, taking up almost no room in your pack. 

So how’d they do it? High-quality down for one. The 900-fill insulation is incredibly lofty for excellent warmth, yet very compressible and lightweight when it’s time to move. The majority of the insulation is also located on the top portion of the sleeping bag, with less behind your back. As much as this insulation distribution helps the weight, it does mean you should have a decently insulated sleeping pad to keep from getting cold. 

Therm-a-Rest has also adopted a fairly narrow design that tapers significantly. This can be bad news for you side-sleepers out there as you may take the sleeping bag with you when you roll and expose the less insulated side to the air. But we understand that sacrifices have to be made to achieve such a lightweight design, and believe the Hyperion 20 may be every ultralight hiker’s dream.

BEST FOR: SIDE-SLEEPING HIKERS    

I count myself amongst the side-sleeping crew, and I know the struggle. Constantly pulling the sleeping bag every which way while getting comfortable. But the Nemo Forte and Viola offer a very compelling solution at a reasonable price! 

Both sleeping bags – the Forte for men and Viola for women – feature a unique spoon-shaped design that’s wider at the elbows and knees. This means you can naturally sleep on your side with your arms and legs bent, and not get caught on the wall of your sleeping bag. The sleeping bag also includes Nemo’s interesting heat gills, allowing you to dump excess heat without getting a cold draft. 

As with any synthetic sleeping bag, we must cope with more weight and less compressibility. This is nevertheless an excellent option for side-sleepers who yearn for a comfortable night’s sleep on the trail.

BEST WINTER BACKPACKING SLEEPING BAG

The Western Mountaineering Kodiak MF is a four season sleeping bag that was designed for backpackers who want to brave extreme conditions in comfort. 

While there are plenty of excellent winter sleeping bags out there, the Kodiak MF is our top choice because it is seriously warm and comfortable. While other bags are equally as toasty, they have a narrower fit that makes them constricting. When it is cold out, we tend to spend more time inside our bags and appreciate the extra room. The Kodiak MF adds a few inches in the shoulders and is generously packed with down making it super lofty. The spaciousness also gives you the option to stuff in an extra quilt if you need to add some warmth. Considering how warm this bag is, it packs down incredibly well. 

If you’re just getting into backpacking the price tag might seem ridiculous but for serious backpackers who value high end gear, it’s a worthy investment. Also, like with all proper winter sleeping bags, the versatility of the Kodiak is limited. It would be way too warm for summer backpacking trips and overkill in mild Spring weather.

The Kodiak MF is also available in a 6 foot and 7 foot version.

BEST SLEEPING BAG FOR WOMEN

The Feathered Friends Egret UL 20 is a high quality three season sleeping bag that is specifically designed for female backpackers. 

What we love the most about this sleeping bag is its attention to detail and female tailored fit. There is extra fill around the chest and in the foot box, two areas where women lose more heat than men. Its 950+ fill is super fluffy and toasty, making it a great option for spring to fall camping. When it comes to quality, weight, packability and warmth, the Egret beats all the other female specific bags, which is why it’s our pick for the best women’s backpacking sleeping bag. 

The biggest drawback is the price, but for this level of comfort and quality, we believe it is worth it considering it has an excellent warmth to weight ratio. Another complaint is the sizing isn’t right for everyone. The Egret comes in two sizes: 5’3” and 5’9”, if you’re somewhere right in between, say 5’6”, you might find the 5’9” option too long. This extra space traps cold air, making the bag feel colder overall. And, the 5’3” option would be too tight to have the hood fit over your head comfortably. If this might be an issue for you, you can check out the unisex version of this bag, called the Swallow which has a 20-degree and 30-degree option. 

The Egret UL is also available in a 30-degree version.

BEST SLEEPING BAG FOR SIDE SLEEPERS

The Big Agnes Sidewinder SL20 is spacious enough to be a game changer for side sleepers but it doesn’t trap cold air as much as other wide options.

What we love the most about the Sidewinder SL20 is that it’s one of the only bags on this list that is truly built for side sleepers. The zipper and the hood face the side. The insulation and shape are all geared toward those who roll over. There is a mesh pocket for your pillow that keeps it in place. There is extra padding at the hip and feet, which are two pressure points for those who tend to flip from side-to-side several times throughout the night. There is plenty of room to curl your knees up without feeling constricted as you might in a mummy bag. 

One complaint we have with this bag is the zipper catches if you aren’t careful despite having an “anti snag zipper”. Maybe we were too rough with it but this could be annoying if you have to get up in the middle of the night. Also, people with wide feet might find the toe box a bit tight. 

The Nemo Disco 15, which is also featured on this list is a close competitor to the Big Agnes Sidewinder SL 20. The Sidewinder gains points on weight (it’s 7 ounces lighter), but it is not as roomy as the Disco. The extra inches on the shoulders and hips are nice but you also have to consider that it’s not the best design for retaining warmth.

The Big Agnes Sidewinder SL 20 also comes in a women’s version.

BEST BUDGET WINTER SLEEPING BAG

The Marmot Trestles 0 is a real find for hikers wishing to explore cold environments. With a durable SpiraFil synthetic insulation, the sleeping bag will keep you warm at temperatures as low as 1.9°F. A 3D hood will provide warmth and comfort for your head; you can also cinch it tightly around your face during freezing nights. Another great feature of the Marmot Trestles is the foot box, which ensures extra comfort and warmth where it’s most needed. 

The Trestles 0 has a full-length, two-way zipper built to prevent snagging. There is also a fold-down second zipper that provides fresh ventilation. In case you need anything during the night, there is an external stash pocket for your essentials. Additionally, the bag has two hang loops for storing or drying out the bag.

BEST DOUBLE SLEEPING BAG

The Feathered Friends Spoonbill UL is a two-person sleeping bag for couples who want to lighten their load.

What we love the most about the Spoonbill UL is it gives couples the warmth and intimacy of being in the same bag without having to give up comfort. There are two hoods and two collars that can be adjusted and a zip on each side so you don’t have to worry about bothering your partner when you get in and out. Feathered Friends trimmed unnecessary insulation from the bottom part of the bag and the floor is made of a super lightweight Dyneema fabric. All of this results in a warm, lightweight and comfortable sleeping bag. 

One of the downsides of the Spoonbill is it’s not great for couples who want to cuddle because of its two separate hoods. Another consideration is its price tag is pretty crazy, however if you consider the price of two premium sleeping bags, it might be worthwhile. It also loses major points when it comes to versatility. If one of you decides to go on a solo trip, you’ll need a different bag.

If the price tag puts you off, check out the Big Agnes Sentinel 30. It is a much more affordable double bag option.

With The North Face Inferno, you never have to sacrifice a good night’s sleep to cold, uneven ground. If you don’t have a mattress with you, no worries – this sleeping bag includes extra water-resistant padding between you and the ground. Since the bag compresses to about the size of a basketball, you may have to leave the sleeping pad behind anyhow.

If there’s any chance of cold or snow on your trek, the Inferno ensures you’re prepared with the appropriate sleeping arrangements. You’re sure going to appreciate a good night’s sleep out in the wilderness more when you wake up warm and well-rested.

If hiking is in your bones, your love of the sport doesn’t magically end in the winter. Well, thankfully sporting goods manufacturers see your obsession and raise you the gear to match it. The Marmot Never Summer, for example, voids the idea of “stepping out of your comfort zone” with your very own comfort zone. 

The sleeping bag makes you feel more like you’re sitting on a rug in front of the fireplace than resting in sub-freezing temperatures. Your entire head will be covered by the hood of this bag and you can even put heating packs in the foot pockets, because it’s impossible to fall asleep with cold feet. Plus, it’s a lot easier to face tomorrow’s summit after getting a good night’s rest tonight.

The Enlightened Equipment Enigma 20 is a minimalist ultralight quilt that is quickly becoming a favorite of long distance hikers.

What we love the most about the Enigma is its round foot box that is sewn shut. This design gives you more foot room while trapping in heat. This makes it a good option for backpackers who are transitioning from using a traditional sleeping bag to using a quilt. All of Enlightened Equipment’s quilts are hand sewn and the quality is top notch. They overfill their quilts by 30% so instead of stuffing them to the minimum amount needed to fill the bag, they pack in extra down to help with any loss in loft due to moisture or dirt. Thru hikers who plan to use this thing for weeks on end without washing it will appreciate this consideration.

Quilts do come with some drawbacks and the Enigma is no exception. Since it is just like a big blanket, it doesn’t have a hood so you’ll want to wear a beanie or down jacket on chilly nights. It also doesn’t have a back so it can be tricky to fully seal up the quilt in cold conditions. 

Enlightened Equipment is a cottage manufacturer based in Minnesota. All of their quilts are highly customizable, which is a great option for thru hikers who really want to have their gear dialed in. It can take over a month for a custom quilt to arrive but luckily, EE does have stock options for those who just want a standard option and don’t have time to wait for a custom quilt to arrive. 

The Enigma is available in 0, 10, 20, 30, 40, and 50 degree versions.

Most mummy sleeping bags are designed primarily for back sleeping, but not everyone can sleep on their backs. Side sleepers unite with this plush sleeping bag! Extra stretch across the knees and generous foot room accommodate restless legs.

With the Nemo Sonic you can get good sleep at normally-uncomfortable temperatures too. The overstuffed down feels like a giant pillow and warms like a toaster. If you start to feel a little too toasty, you can open up the breathable “gills” to let excess heat escape without letting chilly drafts in. This sleeping bag gets all technical, which you can take comfort in as a beginner.

If it’s good enough for technical mountaineering, the Mountain Equipment Iceline will get you through a thru-hike in extreme conditions too. All the details about the features, specialty shell fabric, and lab-tested warmth get a little technical, but all you need to know is you’re getting the best of the best as far as winter sleeping bags go. The company also has programs in place to ensure animal welfare and humane workplace conditions. A lot of heart accompanies their brainpower. 

If you appreciate the finer things in life, this quality, well-constructed mummy suit definitely meets your criteria. Never again will you be able to experience raw nature in its most extreme form in total comfort without this beast of a winter sleeping bag.

The Nemo Forte 35 is an affordable synthetic sleeping bag that has plenty of room for those who love to sprawl out. This bag is a great option for mild weather adventures where you don’t have to travel too far to get to your campsite. 

What we love the most about this bag is its spacious dimensions. If you’ve ever felt trapped in a narrow mummy bag, you’ll love the Forte’s hourglass shape that is wider at the shoulders and feet and slightly tapered at the hips. This design is perfect for side sleepers or people who tend to move around a lot at night. We also loved what NEMO calls thermo gills, they are zips that let the insulation spread apart which is great for warm summer nights.

The biggest drawback of this bag is its weight and pack size. At 2lbs 2 oz, it’s not the best choice for long distance backpacking but is manageable for overnight trips. The Forte uses Primaloft synthetic insulation which has its pros and cons. It doesn’t pack down as small as down but it is far more affordable.

If you love the idea of this bag but wish it had down insulation, check out the Nemo Disco line. 

This sleeping bag also comes in a 20 degree version.

The Nemo Forte also comes in a women’s specific version in both 20 degree and 35 degree versions.  

The Marmot Trestles 0 sleeping bag is a great option for someone looking for a bag that will keep them warm in frigid temperatures, but doesn’t want to break the bank to invest in an expensive cold weather bag.

This bag is rated to keep you warm in temperatures down to 0°F, so it’s a great bag to take with you to the Cascades in Washington or the Sierra Nevadas in California. The bag itself will keep you toasty and cozy and the hood of the bag will provide extra heat for you.

This bag is made with quality material, including a zipper guard to make sure it won’t snag on your bag when you’re zipping it up. A 3D foodbox at the bottom provides warmth, and will also keep you comfortable by providing enough space at your feet so you won’t feel like you’re sardined into a bag.

This bag is a bit heavy, with the regular size weighing in at about 4 ½ lbs, but it sells at a killer price point. It can be hard to find a reliable backpacking sleeping bag for under $150 and, which is why this is a great option for hikers on a budget.

The Therm-a-Rest Space Cowboy 45 is one of the very few sleeping bags with water-resistant synthetic filling. This allows it to increase insulation – even when wet –  while decreasing weight. However, it is designed for summer camping, as it withstands only 45°F. The bag features ThermaCapture zoned insulation that is strategically placed to catch your body’s own rising heat. You can also cinch the hood down around your head for a snuggly, draft-free rest.

To increase versatility, this sleeping bag has loops that you can use to layer more quilts and blankets on it, making it useful in colder conditions. The zipper is snag-free to ensure its durability and ease of use. The Cowboy 45 weighs 1.5 lbs. – average for ultralight sleeping bags – but it can be compressed down to 2 liters of volume, saving lots of valuable space in your backpack.

The Marmot Nanowave 45 is an affordable summer sleeping bag that won’t take up too much room in your backpack. Not only is it cheap, it’s also practical and functional.

In awarding it the winner of the best under $100 category, we realize it’s not quite fair because most other bags on this list have a temperature rating down to around 20 degrees. However, if you’re on a super tight budget and plan to camp from mid-spring to mid-fall, the Nanowave 45 is hard to beat.

Which leads us to the biggest downside of this bag, it is only good in mild weather. But, not everyone needs or wants a super warm bag and if you combine the Nanowave with an extra warm sleeping pad and a thermal liner, you might be able to extend the temperature range of this bag down a few degrees, making it much more versatile. If you’re looking for a warmer budget backpacking sleeping bag, check out the REI Trailbreak 20.

The Marmot Nanowave is also available in a 55-degree and 35-degree version.

The REI Co-op Trailbreak 20 is a budget minded synthetic sleeping bag that was designed for people who are just starting out backpacking. 

Just because this bag is a steal doesn’t doesn’t mean that it is cheap. While the Trailbreak 20 is nowhere near as light, comfortable or packable as the bags at the top of our list, we have to give it credit for being an exceptional value. Its size and weight is manageable for short backpacking trips.

The cash savings do come with some drawbacks.The lining fabric is a bit rough making it much less comfortable than the silky fabric found on many other bags. Also, it doesn’t have a neck baffle, so some heat does escape through the top of the bag. One last nitpick, the Trailbreak doesn’t come with a compression sack, so you’ll need to calculate that into your decision. If you’re on a tight budget and just can’t spring for a better sleeping bag right now, this is a good option to get you out on the trail fast.

Looking for a summer sleeping bag? The REI Trailbreak is also available in a 30-degree version.

The REI Trailbreak comes in a women’s specific which is available as a 20-degree or 30-degree bag. 

The North Face Cat’s Meow is a great option for someone who tends to venture into the outdoors in the spring/summer seasons.

The shell of this bag is made with ripstop nylon, which is a tougher fabric than polyester or just plain nylon, and will ensure your bag won’t shed on you in rocky terrain when you might be camping under the stars instead of inside your tent. 

A fitted hood will provide warmth and can serve as extra cushioning for your head when you lay it down to sleep. There is also a draft collar that will provide extra heat and will prevent heat loss throughout the night.

This bag isn’t going to be the warmest option featured by The Adventure Junkies, so if you know you sleep cold, or you like to hike in the fall/winter season and are looking for a bag to keep you warm at high alpine levels, this may not be the bag for you.

A great bag for any season, The North Face One Bag Sleeping Bag will keep you warm in just about any temperature you can imagine sleeping in down to 5° F. Although there is technically a down layer included in this 3-in-1 bag, we still think the synthetic outer layer makes this one of the best synthetic bag choices on the market today. 

This bag has easy-to-use zippers, so configuring the bags just the way you want them will be a breeze. For mild summer nights, you can opt to use only the super lightweight 40° F outer layer on its own. If there’s a chill in the air, you can pair the blue outer layer with the removable yellow mid-layer and stay warm down to 20°F. And if you’re an extreme camper who loves sleeping outside during the wintertime, then use all three bags for warmth in temperatures down to 5°F!

This is certainly the most versatile bag on the list and it’s very popular among both car campers and backpackers because it just about meets all your wilderness sleeping needs!

The Exped MegaSleep 25 Sleeping Bag is a versatile option for anyone who likes to camp or backpack.

Weighing in at about 2 ½ pounds, this bag isn’t too heavy for a pack, and won’t take up too much space either. The bag has zippers down both sides, so you can get in and out of it easily, and adjust the temperature easily according to your preference. 

This bag is a rectangle shape, so you will have plenty of room to spread out, no matter what your favorite sleeping position is. There is a draft tube along both zippers in this bag that will help prevent heat loss and keep you cocooned into your bag at night. 

Tested to keep you warm down to 25° F, this bag is a great option for spring, summer, or fall camping or backpacking.

The Big Agnes Lost Dog is a cold-oriented sleeping bag that withstands temperatures up to 15°F. It uses FireLine ECO synthetic insulation made from recycled polyester, and the innovative design includes several features for comfort. It has a Free Range hood that allows you to lift your head while keeping a snug fit around your face. The Free Range foot box is similar, giving you some wiggle room. An additional no-draft collar will keep the cold wind out. 

For convenience, a Flex Pad Sleeve can stretch over an insulated sleeping pad for extra warmth. The bag also has a 2-way anti-snag zipper and can be joined with another right-zip sleeping bag. If that doesn’t sound comfy enough, the Lost Dog offers a Pillow Barn feature that makes sure your pillow stays put all night. Although it is on the pricier end of affordable, the extra features make it worth it.

The Sea to Summit Trailhead ThII 30 is another synthetic sleeping bag that retains its insulation abilities even when wet. It uses a unique WaveLoft technique that tangles filling fibers for maximum heat retention up to 30°F. This bag has a tapered rectangular shape, providing you with comfort and room to move. An oversized anti-snag zipper draft tube will guard your whole body against cold chills when you snuggle down in this bag. 

An important characteristic of the THII 30 is its versatility. Its full-length zipper lets you turn this sleeping bag into a quilt. Furthermore, there is a second zipper in the foot box, allowing ventilation for your feet and broad temperature adjustability. Plus, to prevent your frustration, the bag’s lining fabric is directly attached to the shell fabric, which prevents zipper tangles.  This sleeping bag is excellent for backpacking since it weighs about 2.5 lbs – not much more than most ultralight sleeping bags!

BEST WINTER BACKPACKING SLEEPING BAG

The Western Mountaineering Kodiak MF is a four season sleeping bag that was designed for backpackers who want to brave extreme conditions in comfort. 

While there are plenty of excellent winter sleeping bags out there, the Kodiak MF is our top choice because it is seriously warm and comfortable. While other bags are equally as toasty, they have a narrower fit that makes them constricting. When it is cold out, we tend to spend more time inside our bags and appreciate the extra room. The Kodiak MF adds a few inches in the shoulders and is generously packed with down making it super lofty. The spaciousness also gives you the option to stuff in an extra quilt if you need to add some warmth. Considering how warm this bag is, it packs down incredibly well. 

If you’re just getting into backpacking the price tag might seem ridiculous but for serious backpackers who value high end gear, it’s a worthy investment. Also, like with all proper winter sleeping bags, the versatility of the Kodiak is limited. It would be way too warm for summer backpacking trips and overkill in mild Spring weather.

The Kodiak MF is also available in a 6 foot and 7 foot version.

The Marmot Trestles 0 sleeping bag is a great option for someone looking for a bag that will keep them warm in frigid temperatures, but doesn’t want to break the bank to invest in an expensive cold weather bag.

This bag is rated to keep you warm in temperatures down to 0°F, so it’s a great bag to take with you to the Cascades in Washington or the Sierra Nevadas in California. The bag itself will keep you toasty and cozy and the hood of the bag will provide extra heat for you.

This bag is a bit heavy, with the regular size weighing in at about 4 ½ lbs, but it sells at a killer price point. It can be hard to find a reliable backpacking sleeping bag for under $150 and, which is why this is a great option for hikers on a budget.

If you’re on a budget and looking for a highly affordable, cold-bearing sleeping bag, then definitely consider the Kelty Cosmic 0. This bag, although ringing in at a lower cost, will keep you warm down to 2 Degrees Fahrenheit and it comes equipped with all the features you need for a good night’s rest. A draft collar ensures warmth around the neck while the water repellent coating easily wicks away moisture. 

Pack this bag if you’re thinking about a quick, cold weather expedition. You probably won’t want to rely on this bag for long duration expeditions, where you may be spending a lot of time in your tent, but if a quick in-and-out journey is on the docket, then definitely consider saving yourself some money and going with the Kelty Cosmic 0.

If hiking is in your bones, your love of the sport doesn’t magically end in the winter. Well, thankfully sporting goods manufacturers see your obsession and raise you the gear to match it. The Marmot Never Summer, for example, voids the idea of “stepping out of your comfort zone” with your very own comfort zone.

Your entire head will be covered by the hood of this bag and you can even put heating packs in the foot pockets, because it’s impossible to fall asleep with cold feet. Plus, it’s a lot easier to face tomorrow’s summit after getting a good night’s rest tonight.

With zippers galore for a variety of configurations, the Sea to Summit Ascent ACIII is a 0 degree sleeping bag that you can zip together with another bag or unzip completely to lay flat as a warm winter quilt. You can also unzip one side like a standard sleeping bag, half unzip the top layer if you need extra ventilation, or unzip just the foot-box if your feet start to sweat.

The Sea to Summit Ascent ACIII is designed with vertical baffles on the torso, which keep the insulation in place inside the bag and prevents cold spots. The semi-rectangular shape also provides a bit more room than a mummy-style bag, so you can sleep comfortably.

The Big Agnes Lost Dog is a cold-oriented sleeping bag that withstands temperatures up to 15°F. It uses FireLine ECO synthetic insulation made from recycled polyester, and the innovative design includes several features for comfort. It has a Free Range hood that allows you to lift your head while keeping a snug fit around your face. The Free Range foot box is similar, giving you some wiggle room. An additional no-draft collar will keep the cold wind out. 

For convenience, a Flex Pad Sleeve can stretch over an insulated sleeping pad for extra warmth. The bag also has a 2-way anti-snag zipper and can be joined with another right-zip sleeping bag. If that doesn’t sound comfy enough, the Lost Dog offers a Pillow Barn feature that makes sure your pillow stays put all night. Although it is on the pricier end of affordable, the extra features make it worth it.

Even though a sleeping bag is expected to be a bit cramped and tight, to ensure maximum warmth potential is maintained, surely we can wish for a bag with a little bit of wiggle room too? Look no further than the REI Co-op Siesta 25 sleeping bag. This sleeping bag has enough components to meet any needs you may have, including a two-way main zipper, which allows you to unzip the bottom to let your feet have some air if it’s getting a bit too stuffy for your liking.

A shorter zipper on the other side of the bag allows you to fold down the top of the sleeping bag, giving you a bed-like feel. The polyester outside of the bag has been treated with a water resistant agent, so you don’t have to worry if your bag gets a bit damp on your camping trip.

The Sea to Summit Trailhead ThII 30 is another synthetic sleeping bag that retains its insulation abilities even when wet. It uses a unique WaveLoft technique that tangles filling fibers for maximum heat retention up to 30°F. This bag has a tapered rectangular shape, providing you with comfort and room to move. An oversized anti-snag zipper draft tube will guard your whole body against cold chills when you snuggle down in this bag. 

An important characteristic of the THII 30 is its versatility. Its full-length zipper lets you turn this sleeping bag into a quilt. Furthermore, there is a second zipper in the foot box, allowing ventilation for your feet and broad temperature adjustability. Plus, to prevent your frustration, the bag’s lining fabric is directly attached to the shell fabric, which prevents zipper tangles.  This sleeping bag is excellent for backpacking since it weighs about 2.5 lbs – not much more than most ultralight sleeping bags!

A great bag for any season, The North Face One Bag Sleeping Bag will keep you warm in just about any temperature you can imagine sleeping in down to 5° F. Although there is technically a down layer included in this 3-in-1 bag, we still think the synthetic outer layer makes this one of the best synthetic bag choices on the market today. 

This bag has easy-to-use zippers, so configuring the bags just the way you want them will be a breeze. For mild summer nights, you can opt to use only the super lightweight 40° F outer layer on its own. If there’s a chill in the air, you can pair the blue outer layer with the removable yellow mid-layer and stay warm down to 20°F. And if you’re an extreme camper who loves sleeping outside during the wintertime, then use all three bags for warmth in temperatures down to 5°F!

This is certainly the most versatile bag on the list and it’s very popular among both car campers and backpackers because it just about meets all your wilderness sleeping needs!

The Exped MegaSleep 25 Sleeping Bag is a versatile option for anyone who likes to camp or backpack.

Weighing in at about 2 ½ pounds, this bag isn’t too heavy for a pack, and won’t take up too much space either. The bag has zippers down both sides, so you can get in and out of it easily, and adjust the temperature easily according to your preference. 

This bag is a rectangle shape, so you will have plenty of room to spread out, no matter what your favorite sleeping position is. There is a draft tube along both zippers in this bag that will help prevent heat loss and keep you cocooned into your bag at night. 

Tested to keep you warm down to 25° F, this bag is a great option for spring, summer, or fall camping or backpacking.

The Sea to Summit Traverse TvII 25 has a tapered rectangular shape and uses the WaveLoft construction for increased comfort. However, the Traverse TVII 25 has a more expanded range of features. It can withstand temperatures as low as 25°F, allowing you to explore slightly colder environments. And an oversized, anti-snag zipper and a neck draft tube provide exceptional resistance to chilly mountain breezes. 

A Free Flow zipper system in this bag comes with three features that let you customize your temperature. A full-length main side zipper, a half-length opposite side zipper, and a foot zipper all provide you with unrestricted movement and ventilation. As a bonus, the TVII 25 can be zipped up with another bag. This versatility makes up for its higher price, delivering you your money’s worth.

The North Face Dolomite One Duo is a 3-in-1 layering system that is great for couples who plan to camp in a variety of seasons. 

The Dolomite One Duo uses a top layer and mid layer that lets you stack and interchange the two to give you warmth over a wide range of temperatures. The top layer has a 50°F warmth rating and the mid layer has a 30°F warmth rating. When the two layers are paired together you get a 15°F bag. The zippering system lets you have three separate layers, which is nice if you tend to over heat on warm nights or want to use one layer as a blanket around the campfire. It has a roomy, rectangular shape that gives couples plenty of room to move around. 

While this is one of the best 3-in-1 systems we’ve come across, it does have some downsides. The Dolomite One Duo does a bit of everything but doesn’t excel at one category. While it’s not the lightest, warmest, or cheapest two person bag, it is a great option for couples who want a versatile sleep set up they can use while camping and backpacking as well as car camping and RVing.  

This bag is also available in a one person version.

The Nemo Forte 35 is an affordable synthetic sleeping bag that has plenty of room for those who love to sprawl out. This bag is a great option for mild weather adventures where you don’t have to travel too far to get to your campsite. 

What we love the most about this bag is its spacious dimensions. If you’ve ever felt trapped in a narrow mummy bag, you’ll love the Forte’s hourglass shape that is wider at the shoulders and feet and slightly tapered at the hips. This design is perfect for side sleepers or people who tend to move around a lot at night. We also loved what NEMO calls thermo gills, they are zips that let the insulation spread apart which is great for warm summer nights.

The biggest drawback of this bag is its weight and pack size. At 2lbs 2 oz, it’s not the best choice for long distance backpacking but is manageable for overnight trips. The Forte uses Primaloft synthetic insulation which has its pros and cons. It doesn’t pack down as small as down but it is far more affordable.

If you love the idea of this bag but wish it had down insulation, check out the Nemo Disco line. 

This sleeping bag also comes in a 20 degree version.

The Nemo Forte also comes in a women’s specific version in both 20 degree and 35 degree versions.  

The Big Agnes King Solomon 15 is a roomy doublewide sleeping bag that is perfect for couples who are tired of zipping two bags together. 

What we love the most about this bag is how warm and cozy it is. Big Agnes claims it’s like your own bed in the backcountry and we have to agree. We also appreciated the well thought out design of the King Solomon 15. It has vertical baffles that help keep the insulation in place instead of bulking up on one side. It also has a pad sleeve on the bottom to prevent your sleeping pads from slipping out from underneath you and your partner in the middle of the night. 

One of the downsides to an extra spacious bag like this one is it tends to trap a lot of dead air making it not as warm as a snug bag. If you tend to get cold at night, consider adding a thermal liner. Another nitpick with this bag doesn’t work well with narrow sleeping pads, so if you decide to go for the King Solomon, you might want to consider getting a double pad as well. 

If you’re looking for a summer double sleeping bag, check out the Big Agnes Sentinel 30. It has a lot of the same features as the King Solomon but isn’t as toasty. 

The Klymit KSB Double is a two person three season sleeping bag that is a great choice for couples who like to cuddle. 

What we liked the most about the KSB double is it’s two-part system that lets you fully unzip the bag to create a comforter. We found this really handy for warmer nights and car camping. The top layer uses a 650 fill duck down and bottom uses synthetic insulation. This helps cut the overall cost of the bag, but does make it slightly more heavy and bulkier. We appreciated the individual draft covers and hoods, which let us control how much ventilation we wanted. There are two zippers, one on each side so you don’t have to bother your partner when you want to get in or out of the bag.

The KSB Double is rated to 30 degrees, but it might not live up to that rating for all sleepers, especially women. This is a common issue with double sleeping bags because they aren’t nearly as warm as a single mummy style bag. Unless your partner is as warm as an electric blanket, you might want to bring a thermal liner for camping on chilly nights. When it comes to price, the KSB Double is a bit more expensive than similar double bags out there. It’s also quite heavy, weighing in at 4 pounds, 11 ounces, which makes this bag best suited for shorter adventures, car camping or mule assisted trekking.

BEST 4-SEASON BACKPACKING TENT

If you consider other tents on this list as shelters, The North Face VE 25 is a bunker. It’s a part of The North Face Summit Series which is designed for extreme conditions and is tested by their athletes. While it would be considered overkill for most popular hiking destinations, it’s an excellent choice for extreme conditions.  

We loved how well the VE 25 holds up in serious weather. We’re talking loads of snow, ice, wind, and rain. It’s the kind of tent that will save your butt in harsh winter conditions and that’s why it’s our choice for the best 4-season option. It’s extremely liveable which is a big plus for those tent bound days. The inner tent has good tension so it doesn’t flap in the wind. It also has great ventilation, the roof can zip open which provides some airflow. 

The biggest downside is it is really big and really heavy, but that comes with this type of expedition tent. Its performance in high winds could be better. Over 50 mph, the tent starts to struggle. The back of the tent is so broad that it really takes a beating. It’s difficult to set up and take down in these high wind conditions. This is a common disadvantage of high volume tents. 

If you tend to camp in windy conditions, take a look at the Hilleberg Nallo 2 that is also featured on this list. 

The Hyperlite Mountain Gear Ultamid 2 is a super light backpacking tent that weighs just over a pound. Unlike many other ultralight options, it doesn’t sacrifice interior space to cut weight. It’s a great option for any long distance adventure where your tent becomes your home for weeks, months, or maybe even years.

What we love the most about this tent is its spaciousness. It feels like the palace of light backpacking tents. It has a tepee, pyramid shape and is set up by placing two attached trekking poles in the middle of the tent. This makes it super roomy and gives you a ton of headroom, a thru-hiker or bikepackers dream. If you’re camping with friends, be aware that your tent will most likely become the hangout space. The construction and design of the Ultamid 2 is top notch and well thought out. It’s made of DCF (Dyneema composite fabric) which is super strong and has no stretch to it so it won’t sag like nylon when it gets wet. 

All this spaciousness comes at a cost and not just when it comes to cash. The footprint of this thing is huge so you need a campsite that is large enough to be able to pitch it. If you plan to camp in the desert or in open plains it shouldn’t be an issue but it can make it impossible to use in dense woods or forests. Another bummer is the pole support in the middle means no morning cuddles with your partner. 

Want an even bigger tent? Hyperlite also makes a 4-person version of the Ultamid. 

The North Face Mountain 25 is a sturdy four season shelter option with features that ensure a dry and warm night throughout Mother Nature’s worst storm. 

This tent is designed for the ease of the mountaineer using it. It comes with color coded and reflective zippers, to help you with the setup and so you can find it in the dark. The front of the tent has a large, 8 square foot vestibule, roomy enough for all your gear. The vestibule also has dual entry, making it easy to get in and out of.

This shelter comes with a small window, so you can peek outside at the freshly fallen snow as you wake up. The window has been cold-crack tested, and is foolproof to -60° F. This tent includes the footprint.

This tent can be a little difficult to setup the first couple of times, so make sure you give it a trial run or two before you hit the high alpine.

The Hilleberg Nallo 2 is a tunnel tent that was designed for high winds and tough conditions. 

What we love about this tent is how well it balances strength and weight. It’s tough enough to handle storms and powerful winds. The pole sleeves can fit an extra set of poles, which makes the tent much stronger. Also, the fly goes all the way to the ground, which prevents splashback and draft. 

The biggest downside of the Nallo is it underperforms when it comes to heavy snow loading. If you get caught in a snowstorm, either you’d need to get out (or convince your hiking partner to get out) and knock snow off the roof and vestibule to prevent the poles from bending. 

If you’re looking for a tent that can handle extreme winter conditions, have a look at The North Face VE25, which is also featured on this list.

The Nemo Kunai is a 4-season tent that was designed for short and light mountaineering trips. 

What we love about the Kunai is it’s only 4 pounds, which is light for a 4-season winter tent. It has a double wall construction, so the inner isn’t mesh, it’s fully lined. So basically it’s like having two tents. This design is great for insulation and strength. The Kunai can handle extreme weather from strong winds to snowstorms. 

The double wall is great for staying warm and dry but we were concerned about the airflow and condensation. The large vents on the inner tent worked great at keeping the tent ventilated in cool weather. It would be way too warm for summer camping, but that’s not what it’s built for.   

The Nemo Kunai also comes in a 3-person model.

The Marmot Thor 2P is a 4-season shelter that is spacious and durable. 

Meant for trekking at alpine levels, this tent will keep you dry in a storm. The rainfly of this tent is seam sealed and provides two large vestibules on either side of the tent, enough coverage for you and your partner. The rainfly also has two vents, to help prevent condensation inside your vestibule when it’s dumping outside.

The pole design of Marmot’s Thor creates vertical walls inside the tent, creating a spacious interior for you and your partner. This tent also has several storage pockets inside of the tent for all your belongings. 

This tent offers different pitching setups. For a more minimalist hiker, you can set the tent up using the rainfly, poles, and footprint. Although when using the tent in the winter, you will likely want the warmth the tent can provide with a full body set up. 

Whatever your outdoor gig is, this tent is a versatile, reliable, year-round option.

The Marmot Thor also comes in a 3-person version.

The Black Diamond FirstLight is a great option for the ultralight hiker who frequents alpine heights often.

This tent weighs about four pounds and is a quality shelter for rain, snow, hail, or any other stormy weather conditions Mother Nature is sending your way. It will keep you warm and dry and it will be light on your back.

That being said, there are some features you will miss on this tent that other tents in this article have. This tent doesn’t come with a large vestibule for gear storage, so whatever gear you have with you will either have to be waterproof, or will have to be inside your tent with you. 

Due to the lack of vestibule space, the 3-person version of this tent is a better option for a hiker duo and all their gear, whereas three people and all of their gear would be a very tight squeeze. This shelter does have two internal mesh pockets, which will help with gear storage.

BEST SLEEPING BAG FOR SIDE SLEEPERS

The Big Agnes Sidewinder SL20 is spacious enough to be a game changer for side sleepers but it doesn’t trap cold air as much as other wide options.

What we love the most about the Sidewinder SL20 is that it’s one of the only bags on this list that is truly built for side sleepers. The zipper and the hood face the side. The insulation and shape are all geared toward those who roll over. There is a mesh pocket for your pillow that keeps it in place. There is extra padding at the hip and feet, which are two pressure points for those who tend to flip from side-to-side several times throughout the night. There is plenty of room to curl your knees up without feeling constricted as you might in a mummy bag. 

One complaint we have with this bag is the zipper catches if you aren’t careful despite having an “anti snag zipper”. Maybe we were too rough with it but this could be annoying if you have to get up in the middle of the night. Also, people with wide feet might find the toe box a bit tight. 

The Nemo Disco 15, which is also featured on this list is a close competitor to the Big Agnes Sidewinder SL 20. The Sidewinder gains points on weight (it’s 7 ounces lighter), but it is not as roomy as the Disco. The extra inches on the shoulders and hips are nice but you also have to consider that it’s not the best design for retaining warmth.

The Big Agnes Sidewinder SL 20 also comes in a women’s version.

The Marmot Sawtooth is a quality down sleeping bag that incorporates a healthy mix of warmth and water protection given the price. With a comfort rating of 27.1 degrees F, the Marmot Sawtooth will keep you warm on most 3-season backpacking trips. 

For peace of mind when moisture strikes, this down sleeping bag not only incorporates water-repellent down but a durable water-repellent shell as well. The drawcord collar is a nice touch to help cinch this bag down and block out the cold. Should you find temperatures to be colder than expected, stuff a heat packet into the heat pocket at the bottom of the bag and keep your toes nice and toasty.

The Kelty Cosmic 20 is a budget minded down sleeping back that is a great option for new backpackers who don’t mind carrying a bit of extra weight and bulk to save some cash.

What we love the most about this bag is its overall value. The Cosmic’s quality and warmth are great considering how inexpensive it is. Of course, you can’t compare the build and material quality of the Cosmic to the top of the line bags on this list but it is practical and comfortable enough, making it tough competition for other budget options.

The biggest downside of the Cosmic is it is much more heavy and bulky than other backpacking sleeping bags, but hey, it’s one of the cheapest down bags around. If you’re just starting out, you could always go for the Cosmic and if you end up becoming a hiking junkie, you could upgrade and retire this bag to car camping adventures. 

This bag is also offered in 40-degree and 0-degree versions. 

The Kelty Cosmic 20 is also available as a women’s version. 

The Therm-a-Rest Hyperion 20 is a lightweight high quality bag that was designed to help long distance hikers shave pounds from their load.

What we love the most about this bag is its warmth to weight ratio. It’s filled with 900 down which makes it so warm and light. It also packs down quite small, making it great for saving room in your backpack. A little feature we liked was there are two straps underneath it which you can attach to your sleeping pads to keep the bag from slipping off. The Hyperion comes with a compression bag which helps get the bag down to about the size of a large water bottle. There is more insulation on top (70%) and less on the bottom (30%), this saves weight but it also means the design is optimized for sleeping on your back. 

What this bag gains in weight saving, it pays for in comfort. The cut is slim, very slim. So, if you’re a bigger dude or lady, you will probably feel constricted in this thing. The Hyperion is very narrow throughout and tapers down even more at the feet. The zipper only goes halfway down the bag, which does shave some ounces but it also means you can’t vent your feet. And, while we’re talking about the zipper, let’s just say it has some room for improvement. There’s a bit of fabric that runs along the zipper but it still snags from time to time. 

The Hyperion 20 is excellent value for money and is cheaper than other high end bags on this list, but it is lacking some features like a draft collar that lets you seal the bag around your face. Also, while it’s rated to 20 degrees, its comfort rating is 32 degrees. So we only recommend this  bag for above freezing conditions. If you’re the kind of hiker who doesn’t mind sacrificing some comfort in order to go fast and light, the Hyperion 20 could be the perfect bag for you. 

This bag also comes in a 32 degree version.

BEST BACKPACKING SLEEPING BAG UNDER $100

The Marmot Nanowave 45 is an affordable summer sleeping bag that won’t take up too much room in your backpack. Not only is it cheap, it’s practical and functional which is why it’s our pick for the best backpacking sleeping bag under $100. 

In awarding it the winner of the best under $100 category, we realize it’s not quite fair because most other bags on this list have a temperature rating down to around 20 degrees. However, if you’re on a super tight budget and plan to camp from mid-spring to mid-fall, the Nanowave 45 is hard to beat.

Which leads us to the biggest downside of this bag, it is only good in mild weather. But, not everyone needs or wants a super warm bag and if you combine the Nanowave with an extra warm sleeping pad and a thermal liner, you might be able to extend the temperature range of this bag down a few degrees, making it much more versatile. If you’re looking for a warmer budget backpacking sleeping bag, check out the REI Trailbreak 20 which is also featured on this list. 

The Marmot Nanowave is also available in a 55-degree and 35-degree version.

BEST DOUBLE SLEEPING BAG

The Feathered Friends Spoonbill UL is a two-person sleeping bag for couples who want to lighten their load.

What we love the most about the Spoonbill UL is it gives couples the warmth and intimacy of being in the same bag without having to give up comfort. There are two hoods and two collars that can be adjusted and a zip on each side so you don’t have to worry about bothering your partner when you get in and out. Feathered Friends trimmed unnecessary insulation from the bottom part of the bag and the floor is made of a super lightweight Dyneema fabric. All of this results in a warm, lightweight and comfortable sleeping bag. 

One of the downsides of the Spoonbill is it’s not great for couples who want to cuddle because of its two separate hoods. Another consideration is its price tag is pretty crazy, however if you consider the price of two premium sleeping bags, it might be worthwhile. It also loses major points when it comes to versatility. If one of you decides to go on a solo trip, you’ll need a different bag.

If the price tag puts you off, check out the Big Agnes Sentinel 30. It is a much more affordable double bag option.

The Big Agnes Sentinel 30 is a double sleeping bag that is a great option for couples looking for an affordable 2-person bag. 

What we love the most about this bag is that it gives you all the warmth advantages of sharing one bag while still being roomy and comfortable. We also liked the price point, it’s not super expensive like the Feathered Friends Spoonbill nor is it too bulky or heavy for backpacking, like some cheaper options. The Sentinel comes with a Flex Pad Sleeve which makes connecting two pads easy. Alternatively, you could stretch it around a double wide pad. 

The biggest drawback of this bag, and double bags in general is its lack of versatility. If one partner wants to go solo backpacking for a few nights, she’ll need another bag.

If you want a more premium sleeping bag for you and your adventure partner, check out the Feathered Friends Spoonbill UL. While it’s over double the price, it is much lighter and compressible than the Sentinel. 

The North Face Dolomite One Duo is a 3-in-1 layering system that is great for couples who plan to camp in a variety of seasons. 

The Dolomite One Duo uses a top layer and mid layer that lets you stack and interchange the two to give you warmth over a wide range of temperatures. The top layer has a 50°F warmth rating and the mid layer has a 30°F warmth rating. When the two layers are paired together you get a 15°F bag. The zippering system lets you have three separate layers, which is nice if you tend to over heat on warm nights or want to use one layer as a blanket around the campfire. It has a roomy, rectangular shape that gives couples plenty of room to move around. 

While this is one of the best 3-in-1 systems we’ve come across, it does have some downsides. The Dolomite One Duo does a bit of everything but doesn’t excel at one category. While it’s not the lightest, warmest, or cheapest two person bag, it is a great option for couples who want a versatile sleep set up they can use while camping and backpacking as well as car camping and RVing.  

This bag is also available in a one person version.

The Big Agnes King Solomon 15 is a roomy doublewide sleeping bag that is perfect for couples who are tired of zipping two bags together. 

What we love the most about this bag is how warm and cozy it is. Big Agnes claims it’s like your own bed in the backcountry and we have to agree. We also appreciated the well thought out design of the King Solomon 15. It has vertical baffles that help keep the insulation in place instead of bulking up on one side. It also has a pad sleeve on the bottom to prevent your sleeping pads from slipping out from underneath you and your partner in the middle of the night. 

One of the downsides to an extra spacious bag like this one is it tends to trap a lot of dead air making it not as warm as a snug bag. If you tend to get cold at night, consider adding a thermal liner. Another nitpick with this bag doesn’t work well with narrow sleeping pads, so if you decide to go for the King Solomon, you might want to consider getting a double pad as well. 

If you’re looking for a summer double sleeping bag, check out the Big Agnes Sentinel 30. It has a lot of the same features as the King Solomon but isn’t as toasty. 

The Big Agnes Cabin Creek 15 is you and your adventure partner’s answer to cold weather camping. With a temperature rating of 15-degrees Fahrenheit, this double sleeping bag will serve you well as a 3-season bag along with mild winter camping. 

Slip on in and bundle up by cinching down on the internal drawcord and wrapping the corner pocket around your shoulders. Find your comfy spot and enjoy the extra foot room with the spacious footbox. Big Agnes also did you a solid by incorporating zippers on each side so there’s no need to wake up your partner if you need to climb out at night.

Tired of zipping two sleeping bags together? Then you will want to take a look at what the Nemo Jazz Duo has to offer. This sleeping bag built for two features an integrated design that attaches the sleeping bag to your sleeping pad to keep everything in place. With dimensions equivalent to a queen-size bed, you’ll find ample room for your hiking partner and your little tyke or furry friend. 

For additional comfort, Nemo incorporated a built-in pillowtop and a proprietary Blanket Fold that tucks in around your neck, sort of like your comforter at home. While the Nemo Jazz Duo may be on the heavy side, the size makes it a great choice for the family looking to do a casual overnighter backpacking trip.

The Klymit KSB Double is a two person three season sleeping bag that is a great choice for couples who like to cuddle. 

What we liked the most about the KSB double is it’s two-part system that lets you fully unzip the bag to create a comforter. We found this really handy for warmer nights and car camping. The top layer uses a 650 fill duck down and bottom uses synthetic insulation. This helps cut the overall cost of the bag, but does make it slightly more heavy and bulkier. We appreciated the individual draft covers and hoods, which let us control how much ventilation we wanted. There are two zippers, one on each side so you don’t have to bother your partner when you want to get in or out of the bag.

The KSB Double is rated to 30 degrees, but it might not live up to that rating for all sleepers, especially women. This is a common issue with double sleeping bags because they aren’t nearly as warm as a single mummy style bag. Unless your partner is as warm as an electric blanket, you might want to bring a thermal liner for camping on chilly nights. When it comes to price, the KSB Double is a bit more expensive than similar double bags out there. It’s also quite heavy, weighing in at 4 pounds, 11 ounces, which makes this bag best suited for shorter adventures, car camping or mule assisted trekking.

The Big Agnes Camp Robber Double is like sleeping on a cloud despite being on the cold hard ground. The plush 650-fill down quilt feels like backcountry luxury while the fitted pad cover is soft to the touch. 

Whether you and your backpacking partner sleep with the quilt fully zipped or like a throw, you’ll love all this yummy comfort. And the best part? You can have all this without the weight. Weighing less than 4-pounds, the Big Agnes Camp Robber Double is light enough to stuff inside your backpacking pack and not make you feel guilty about added weight for the sake of comfort.

The Exped MegaSleep Duo 25 offers incredible bang for your bang. This double sleeping bag features a clever design that offers two temperature ratings. If it’s chilly out, sleep with the dark blue side up and stay toasty down to 25-degrees Fahrenheit. If it happens to be warmer out, the light blue side will keep you warm as long as temps don’t go below 40-degrees Fahrenheit. 

Stuff the Exped MegaSleep Duo 25 into your pack and unravel at camp. This double sleeping bag is compressible without losing loft so you can maximize insulation. Soft to the touch, the Exped MegaSleep Duo is an affordable option for the camping couple who want comfort and don’t mind a little extra bulk.

Big Agnes named this sleeping bag Dream Island for a reason. This giant sleeping bag is pure camping luxury with its warm insulation and spacious interior. 

Snuggle up inside and get warm. The cozy hood and no-draft collar will prevent heat from escaping. Meanwhile, if one of you happen to get a little too warm, you can unzip the anti-snag zipper on your side and let out some of that body heat without disturbing your partner. While the Big Agnes Dream Island is certainly a luxury, it will cost you in weight and space. That said, if you’re not going far, this double sleeping bag may be right up your alley.

BEST BACKPACKING SLEEPING BAG OVERALL

The Western Mountaineering UltraLite is an ultra light and ultra premium backpacking sleeping bag that is our pick as the best overall choice.

What we love the most about this bag is its balance between weight, quality, versatility and comfort. It is rated to 20-degree and only weighs 17oz making it an excellent choice for fast and lite colder weather trips. The UltraLite’s horizontal baffle design allows you to move the feathers to the back of the bag, making it less warm for spring and mild summer conditions. 

The biggest downside of the UltraLite is its price tag. At $525, it’s one of the priciest bags on our list. However, if you’re a true backpacking junkie who wants an all around awesome bag, it might be a worthy investment. 

A close contender to the UltraLite is the Feathered Friends Hummingbird YF20 (and similar bags within their range). If you’re having trouble deciding, one feature we loved about the UltraLite that we didn’t find on others is the full goose down draft collar. This lets you bunker down and seal your body heat, a much appreciated feature on chilly nights.

BEST SLEEPING BAG FOR BIG GUYS AND TALL PEOPLE

The Nemo Disco 15 is a roomy backpacking sleeping bag that was designed for comfort. The Disco is our top choice for big and tall guys (and ladies) who might feel claustrophobic in a typical mummy bag. It’s also another great option for side sleepers. 

What we loved the most about the Disco is its spacious dimensions. This is thanks to what Nemo calls their Classic Spoon shape, which makes the bag wider in the elbows and knees.  We also loved the Therma-gills which are vents that allow you to fine-tune the temperature without having to unzip the bag. This feature makes it a more versatile bag that could be comfortable to use in warmer temps. 

The biggest drawbacks of the Nemo Disco are it’s on the heavier, bulkier end when it comes to backpacking sleeping bags. The weight and packsize penalty come with the extra fabric needed to make this roomy bag. So, if you are a bigger guy or gal or you just like to sprawl, and you don’t mind hauling extra weight, the Disco 15 might be the best option for you. If the weight is a big concern for you, check out the Nemo Riff 15, it’s not only lighter but also more packable. One more downside is the wider design is that cold pockets of air can form in the empty spaces, something to consider if you are a cold sleeper. 

This sleeping bag also comes in a 30 degree model. 

The Nemo Disco also comes in a women’s version which is available in 15 degree and 30 degree options.

BEST ULTRALIGHT SLEEPING BAG

The Feathered Friends Hummingbird UL 20 is a super light and packable three season sleeping bag. It’s our pick for the best ultralight backpacking sleeping bag.

What we loved the most about the Hummingbird is the conservative, even borderline generous temperature rating. This is not something we could say about a lot of other ultralight bags out there. The Hummingbird is stuffed with 950+ goose down which makes it extremely warm and light.

One drawback of the Hummingbird is the fit is pretty snug. If you’re a side sleeper or a bigger guy or gal, you might find the narrow dimensions claustrophobic. If you toss and turn a lot and would prefer a more spacious bag, check out the Feathered Friends Swallow and Swift. Another downside is since Feathered Friends is a cottage manufacturer, stock can sometimes be limited and wait times can be long. If you love the idea of owning a handmade sleeping bag that is tailored to your needs, be sure to order well ahead of your next trip.

The Hummingbird UL is in close competition with Western Mountaineering’s UltraLite. which is also featured on this list. While both are excellent choices for serious backpackers, the Hummingbird is 5 ounces lighter, making it a winner for those who are meticulous about cutting weight.

The Hummingbird UL is also available in a 30-degree version.

The Kelty Cosmic 20 is a budget minded down sleeping back that is a great option for new backpackers who don’t mind carrying a bit of extra weight and bulk to save some cash.

What we love the most about this bag is its overall value. The Cosmic’s quality and warmth are great considering how inexpensive it is. Of course, you can’t compare the build and material quality of the Cosmic to the top of the line bags on this list but it is practical and comfortable enough, making it tough competition for other budget options.

The biggest downside of the Cosmic is it is much more heavy and bulky than other backpacking sleeping bags, but hey, it’s one of the cheapest down bags around. If you’re just starting out, you could always go for the Cosmic and if you end up becoming a hiking junkie, you could upgrade and retire this bag to car camping adventures. 

This bag is also offered in 40-degree and 0-degree versions. 

The Kelty Cosmic 20 is also available as a women’s version. 

The insulating features of the Marmot Hydrogen Down Sleeping Bag will surely keep you warm even through colder nights. An insulated tube covers the 2-way anti-snag zipper to prevent any cold breeze from seeping in. A fold-down second zipper equips you with ventilation, so you won’t overheat on warmer nights. Moreover, an insulated hood will warmly cradle your head thanks to its multi-baffle design that keeps the down from moving by separating it into different compartments. And cinching drawcords at the top of this bag allow you to secure the hood around your face to prevent wind from chafing your face all night. 

Unlike a caterpillar cocoon, this mummy sleeping bag is durable and sure to live a long life. It has two hang loops for storing, drying, or just airing out the bag to help increase its lifespan with proper care. Another nifty feature includes an internal stash pocket perfect for keeping nighttime essentials and valuables nearby. Considering all these specs, the bag’s super light weight of 1 lb. 7 oz. is almost unbelievable.

The Therm-a-Rest Hyperion 20 is a lightweight high quality bag that was designed to help long distance hikers shave pounds from their load.

What we love the most about this bag is its warmth to weight ratio. It’s filled with 900 down which makes it so warm and light. It also packs down quite small, making it great for saving room in your backpack. A little feature we liked was there are two straps underneath it which you can attach to your sleeping pads to keep the bag from slipping off. The Hyperion comes with a compression bag which helps get the bag down to about the size of a large water bottle. There is more insulation on top (70%) and less on the bottom (30%), this saves weight but it also means the design is optimized for sleeping on your back. 

What this bag gains in weight saving, it pays for in comfort. The cut is slim, very slim. So, if you’re a bigger dude or lady, you will probably feel constricted in this thing. The Hyperion is very narrow throughout and tapers down even more at the feet. The zipper only goes halfway down the bag, which does shave some ounces but it also means you can’t vent your feet. And, while we’re talking about the zipper, let’s just say it has some room for improvement. There’s a bit of fabric that runs along the zipper but it still snags from time to time. 

The Hyperion 20 is excellent value for money and is cheaper than other high end bags on this list, but it is lacking some features like a draft collar that lets you seal the bag around your face. Also, while it’s rated to 20 degrees, its comfort rating is 32 degrees. So we only recommend this  bag for above freezing conditions. If you’re the kind of hiker who doesn’t mind sacrificing some comfort in order to go fast and light, the Hyperion 20 could be the perfect bag for you. 

This bag also comes in a 32 degree version.

The Big Agnes Anvil 15 has a clever design uncommon in other sleeping bags. It includes a flexible sleeve on the bottom of the bag that attaches to your sleeping pad – think fitted mattress sheet. This means no slipping and sliding off your sleeping pad as you toss and turn at night. There’s even a space to tuck in your pillow so it won’t slip out from under your head. 

Along with the integrated system, the Big Agnes 15 is rather roomy and cozy enough for a chilly night. That said, this does add extra weight and some may find the innovative construction to be annoying rather than helpful, so if you fall into this category you may want to look elsewhere.

Not a fan of the super slim mummy bags? Then take a look at the Sea to Summit Ascent AcI25. This down sleeping bag takes the mummy bag shape and beefs it up to give you extra wiggle room. 

To keep the down right where it belongs, the Sea to Summit Ascent AcI 25 incorporates horizontal baffles around the anatomically shaped footbox and vertical baffles around the chest. Climb on in and cinch down on the large hood. The draft collar is also amped up to prevent the cold from seeping in around the head area so you can get a good night’s rest no matter how chilly it is outside.

The Marmot Sawtooth is a quality down sleeping bag that incorporates a healthy mix of warmth and water protection given the price. With a comfort rating of 27.1 degrees F, the Marmot Sawtooth will keep you warm on most 3-season backpacking trips. 

For peace of mind when moisture strikes, this down sleeping bag not only incorporates water-repellent down but a durable water-repellent shell as well. The drawcord collar is a nice touch to help cinch this bag down and block out the cold. Should you find temperatures to be colder than expected, stuff a heat packet into the heat pocket at the bottom of the bag and keep your toes nice and toasty.

If cutting ounces are a concern to you, you’ll want to consider the Big Agnes Pluton UL 40. This down sleeping bag clocks in at an exceptionally light weight of 1 pound, 3ounces, making it one of the lightest bags around. 

Along with the featherweight, the Big Agnes Pluton UL 40 is packed with highly compressible, water-repellent 850-fill down. This means this sleeping bag is not only super lofty, but it also won’t lose said loft when moisture strikes. Should you be backpacking on a warmer night, unzip the two-way zipper and turn it into a quilt. The one drawback you’ll find is this bag doesn’t give much wiggle room, so expect to sleep in full mummy fashion when not fully unzipped.
