The Top-Rated Sleeping Bags For Camping In The Summer and 3-Seasons
May 20th, 2026, updated with 3 new bags tested, a new winner for best cold weather sleeping bag, best car camping sleeping bag, best 3-in-1 sleeping bag, best kids' sleeping bag, best mummy bag, updated prices and commentary about value, to remove discontinued products
Home > Gear Reviews > Camping
A good camping sleeping bag is what stands between a great night outside and a miserable one. Temperature ratings, insulation type, and fit all matter more than most first-time buyers expect, and the wrong bag for the conditions will leave you cold, clammy, or both by 3am regardless of what your tent or mattress cost.
I'm a camping guide who runs the Bus for Outdoor Access and Teaching, a camping program featured in National Geographic. I use a camping sleeping bag for months every year as part of my job and tested these bags with teenagers who are notoriously hard on gear, which turned out to be one of the more useful durability tests we ran.
What separates a genuinely good camping sleeping bag from one that disappoints comes down to whether the temperature rating is accurate rather than aspirational, how the insulation type performs in humid or wet conditions, how the shape fits different sleep styles, and how the bag holds up to repeated use and washing over seasons. For most campers, comfort and packability matter more than ultralight weight.
Top Pick: The Kelty Cosmic 20 (men's and women's) earns our Best Overall award. It stood out as the most comfortable bag we tested by a clear margin, with a silky soft polyester lining that feels more like sleeping on a bed sheet than a camping bag, an accurate 30 degree comfort rating, a semi-rectangular shape with a wider footbox than most mummy bags, and a price that competes directly with synthetic options despite being down.

The Best Camping Sleeping Bags
Best Overall Camping Sleeping Bag: Kelty Cosmic 20
Temperature rating: 21°F
Insulation: 550 fill down
Packed size: 8 x 13
Weight: 2.6
Style: Semirectangular mummy
What we liked: comfort, better durability than synthetic bags, spacious rectangular design, silky feel of fabric, quality for the price, weight
What we didn’t like: rated to 30F means it is best for summer use
Of all the camping sleeping bags we tried, nothing on the market beats the Kelty Cosmic 20 for best camping sleeping bag. It was my favorite bag for comfort during testing, largely due to the silky feel of the fabric. Even better, it is a great bang for the buck, performing similarly to bags nearly twice its price.
Kelty advertises their “silky soft” polyester, and it’s true: this was the most comfortable bag I slept in while testing. While many folks think a synthetic sleeping bag is best for camping, the Kelty Cosmic was so comfortable and affordable, we think it's worth re-considering that old camping myth, especially if you camp in drier climates.
Kelty has a knack for reinventing classic designs with modern technology. The Kelty Cosmic is rated at an accurate comfort 30℉ and features a spacious rectangular design. The women's version weighs a little extra (it includes extra insulation) but is actually rated accurately for warmth and is the same price as the men's. That's another thing we like about this bag.
Best yet, it’s 2 lb, 10 oz (for men's), making it one of the lightest camping sleeping bags we considered. While it isn’t as light as a backpacking sleeping bag, it can certainly be a decent option to bring on the occasional backpacking trip.

Unlike most camping sleeping bags, which use a synthetic insulation, the Kelty Cosmic bag is made of down. This gives it a softer "floatier" feel than other bags. It also means that it will stay warm year-after-year, unlike synthetic insulation which compress and become less warm over time.
This is why down bags will last longer than most synthetic bags–in some cases, lasting decades. While many down bags are more expensive than synthetic bags, the Kelty Cosmic is competitively priced against similar synthetic sleeping bags, including our best synthetic winner, the REI Co-op Siesta Hooded.
The shape is semi-rectangular, which allows you to have a hood while also allowing for some additional comfort over a traditional mummy bag. For example, the footbox is wider than you’d find in most mummy bags so you can wiggle your toes.
-
If you’re not used to sleeping bags, consider bed sheets — a higher thread count feels softer on the skin than a cheaper, low thread sheet. This bag mimics the feel of sheets. Instead of feeling like you are sleeping on plastic like some camp bags, the Kelty Cosmic feels like sleeping on a sheet at home.
Rated for 30F, the Kelty Cosmic has standard features — extra “baffles” (wads of extra insulation) covering the zipper to keep warmth in. That feature, called a draft tube, is usually found in more expensive sleeping bags, like the ones in our Best Backpacking sleeping bags guide. It also has a dual non-stick zipper so you can add extra ventilation on warmer nights. We also appreciated the stash pocket to keep lip balm, a headlamp, or your phone.
-
While down isn’t for every camper, we think if you are open to it, you’d be hard-pressed to find a better option for the price than the Kelty Cosmic 20. The most significant advantage of down is its ability to better insulate at a lighter weight than synthetic. That’s one reason nearly every sleeping bag in our Best Backpacking Sleeping bags guide is made of down.
The Cosmic uses 550 fill down. This means that an ounce of down could fill 550 cubic inches. More expensive backpacking sleeping bags use higher fill down. For camping, you generally don’t need to be as concerned about the weight and compactness as you do for backpacking and that is how the Cosmic is so affordable. You can read more about what down fill weight means here.
The Cosmic Down 20 has a 30℉ comfort rating (the “20” in the name references the extreme rating)., We think 30℉ is respectable for most summer camping purposes. The lack of a hood and baffles around the shoulders means this bag shouldn’t be used in extreme conditions — buy a specialized down backpacking bag for those uses.
The Kelty Cosmic Down 20 reminds us of our former best overall, the Kelty Tuck, which was the synthetic version of this bag. The Cosmic has almost all the features we liked in the Tuck in a bag that is lightweight and more comfortable made of down that will last years longer, making it our new overall winner.
Best Budget Camping Sleeping Bag: REI Trailmade 25
Temperature rating: 20°F (Lower Limit), 31°F (Comfort Limit)
Weight: 2 lbs. 15.14 oz. (medium)
What we liked: value for the price, lots of size and width options, relatively lightweight, left and right zip options, eco-friendly materials, can double as backpacking sleeping bag
What we didn't like: bulky and heavier than other mummy bags (but pretty standard for camping sleeping bags)
The REI Trailmade is one of REI's most affordable camping sleeping bags and packs a lot of quality in its sub-$130 price. Unlike a lot of budget bags, it has an accurate third-party tested temperature rating of 21F. We also like that it is available in a lot of sizes from short to long and includes wide sizing, too. It also has left and right zip versions, which means it is easier for folks who are left-handed to get out.
The hood fits a camping pillow and it has snag-resistant zippers as well as an external stash pocket. As with many REI items, it contains bluesign certified materials and is made of 98% recycled polyester.
While it's a little bulky and heavy, we don't think that matters as much for a camping sleeping bag, especially for the great value you get on this bag.

Many other review sites recommend the Coleman Dunnock (rated 20℉) as a budget bag. I want to acknowledge it because it can work if you need a cheap bag for sleepovers or the backyard. But the Coleman Dunnock loses versatility quickly.
For $90, it’ll get the job done if you need something for using in cabins and yurts or keeping dog hair from your car. That may be true — but why not just buy a blanket? Same service, a fraction of the price. We have an entire guide to Best Outdoor and Camping Blankets that are specifically designed for things like being abrasion-resistant to dog feet.
Instead, we prefer spending $20 more for the REI Trailmade sleeping bag as the best budget bag. It’s affordable, made of quality materials (even recycled and bluesign materials!), has longevity, and can work camping, in backyards, or even backpacking in a pinch. Moreover, as mentioned above, it’s wildly comfortable. The design allows it to operate effectively in a range of conditions, and it is rated down to 20℉. Not bad for under $130!
Temperature rating: 15°F (30F also available)
Insulation: 650FP RDS Down
Packed size: 8.5 x 11.5 (men's), 8.5 x 12 (women's)
Weight: 2 lbs 11 oz (men's), 3 lbs 5 oz (women's)
Style: Mummy
What we liked: generous and roomy, great for side sleepers, made of recycled material, can be recycled at end of life, lightweight enough for backpacking, best sustainability
What we didn't like: more expensive than most camping bags (but reasonably priced for a backpacking sleeping bag)
If you are looking for a bag that can flex into cold weather camping trips while keeping the perks of a casual bag (more comfortable and cozy), we think the best option is the Nemo Disco Endless Promise. Due to its generous and roomy Spoon shape. Our tester wrote, "I think the design and shape make the Disco Endless Promise my favorite piece of gear next to my Big Agnes tent."
Rated to 15F, it is one of the few camping bags we tested that is roomy and warm. Plus, it is one of the most sustainable bags you can get. Usually, campers have to choose between these features. Not the case with the NEMO Disco.
The NEMO Disco is also the winner of Best Plus Size Backpacking Sleeping Bag and offers great value for a down camping sleeping bag for campers and backpackers of all sizes.
You can read more about why we love this sleeping bag in our in-depth review of the NEMO Disco Endless Promise sleeping bag.
Nemo Disco Endless Promise
Men's
Women's
The Nemo Disco Endless Promise has an innovative Spoon Shape that works for some wider bodies.
-
Treeline Review writer Gabi Reyes-Acosta tested the Disco 15 Endless Promise on everything from warm summer nights to the cold shoulder season in Southern Idaho and the Tetons in Wyoming. It not only kept them warm, but it was deemed the roomiest sleeping bag with a spoon shape (hourglass) made for side sleepers and some plus size folks.
-
Treeline testers of all sizes found the NEMO Disco Endless Promise to be incredibly warm. We found the temperature ratings to be true, something that isn't always the case with camping sleeping bags.
The NEMO Disco 15 Endless Promise features a draft collar and draft tubes along the zipper to prevent cold air from seeping in. This helps to create a cozy and insulated sleep environment, even in chilly weather conditions.
Gabi writes, "As someone who has struggled to find backpacking sleeping bags to fit my size 20/22 body, I found that I could sleep in the Disco Endless Promise without compromising warmth–a problem I have encountered in the past with most mummy bags I have used."
-
The bag also comes with a built-in pillow pocket, where you can insert extra clothing or a camping pillow for added comfort.
-
The NEMO Disco Endless Promise is made of 100% recycled polyester ripstop that is re-engineered to be fully recyclable at the end of its life. The end goal is to keep gear out of landfills by designing for circularity, an idea that captures repairable, resellable, and recyclable. It's also made with a PFAS-free CO Durable Water Repellent.
As part of the Endless Promise, the down can be recycled and reused as part of NEMO's takeback program.
-
At 2 lbs. 14 oz. you could find lighter bags for backpacking. However, remember that weight and insulating ability are correlated — at 15F, the Nemo Disco can handle most temperatures you should consider going out in as a beginner. It’s one of the most popular sleeping bags at REI and is made of 650FP RDS down fill with a unique shape that is roomy and comfortable for side-sleeping.
Best 3-in-1 Camping Sleeping Bag: The North Face One
Temperature rating: 5°, 20°, 40°F
Insulation: Synthetic/ 800-fill down
Packed size: 8 x 15 (for all layers)
Weight: 3.8
Style: Mummy
What we liked: innovative design icludes three sleeping bags in one, can tailor to your temperature needs
What we didn’t like: zippers can lead to user error, weight
If you are only going to buy one bag and are willing to spend, it’s hard to argue with the The North Face One Bag. Although it’s more expensive than the other bags, it’s also three sleeping bags in one.
The core is a 40F synthetic bag, which can unzip entirely from the bottom and act as a blanket. If that’s not warm enough, you can replace the top with a down bag that is rated to 20F. And to wrap it up, you can combine all three — synthetic exterior, down interior, and base — for a 5F bag. So for the price of one camping sleeping bag, you get essentially five combinations of sleeping bags and blankets.
The North Face One
-
Another thing we like about this sleeping bag is that it uses high-end insulation in every component. The down blanket uses 700 fill power recycled down for a good warmth to weight ratio similar to what you’d find in a Backpacking Sleeping bag.
The top layer is made of a synthetic insulation that is warm when wet and can also protect the down insulation and other layers from moisture. This is a similar system found in many cold weather sleeping systems. You can read more about Down vs Synthetic insulation here.
-
Another clever design feature is an anti-compression layer on the bottom that is made of synthetic insulation. Because it stays warm when wet, if your tent leaks or you accidentally set up in a puddle, you’ll still be insulated underneath.
Another nice touch is that the compression sack is made of fleece, so it can double as your camping pillow.
-
The North Face One’s temperature rating is standardized by independent testing by the International Organization for Standardization (ISO) 23537 protocol, which improves on the older European Norm (EN) 13537 standard you may see listed on some bags. It assumes that you’ll be sleeping on a camping mattress or sleeping pad with a minimum R-value of 5.38 (you can learn more about what R-value means here).
The North Face One Bag has some sustainability features we like, such as recycled down insulation, recycled nylon taffeta shell, and non-PFC durable water repellent (DWR) finish.
More zippers do mean more weight. At 3 lbs. 12 oz. all together, it is a heavier bag (though not unreasonable for 5℉). Some reviewers also flagged that multiple zippers led to more user error, though they are helpfully color-coded. Those might be tradeoffs for a performance backpacking bag, but this is an excellent option for a multi-use camping bag.

Best Synthetic Sleeping Bag: REI Siesta Hooded 20
Temperature rating: 25°F
Insulation: Synthetic
Packed size: 11 x 17
Weight: 4.4
Style: Rectangular
What we liked: roomy rectangular shape, has a hood (rare in rectangular bags), quality and value for the price, available as double bag
What we didn't like: not as comfortable as other bags we tested
It can be surprisingly difficult to keep a sleeping bag dry (especially in wet climates), so it’s often best to start with a synthetic bag that can handle some moisture.
Of the numerous synthetic bags out there, we like that the REI Co-op Siesta Hooded for its large size and comfortable rectangular shape. Best yet, rare among sleeping bags, this sleeping bag is rectangular and hooded. It's also among the most affordable sleeping bags we considered.
REI Siesta Hooded 20
In testing, we liked that it is full of clever features that make it easier to regulate temperature on a camping trip. For example, the Siesta Hooded also has a 2-way main zipper that allows the bag to be used fully open as a quilt. We also liked that it can also unzip just the foot box for extra ventilation.
If a hood is a deal-breaker for you, the Siesta Hooded is a good choice that allows you to have a rectangular bag. It’s also available as a double bag, where both campers can still keep their own hood to keep the head warm.
Best car camping sleeping bag: Big Agnes Echo Park
Temperature rating: 20°F
Insulation: Synthetic
Weight: 5.0
Style: Rectangular
What we liked: warmth, value for price, versatility, roomy size, great for big and tall campers, plush, comfort
What we didn't like: bulky and heavy (which is why it is best for car camping)
The Big Agnes Echo Park feels like bringing a bed to the woods. It’s plush and roomy, making for a comfortable sleeping experience. It's warm with features like a comforter in your bed. The Echo Park is our tester's favorite car camping bag they have ever used, and is sized well enough to fit adventurers of many sizes.
While the Big Agnes Echo Park costs a little more than the REI Siesta sleeping bag (review above), the Echo Park is much warmer and has better ventilation for hot nights. That makes it more versatile.
We also found the Echo Park's rectangular sizing to be roomier, which is why it won best car camping sleeping bag in our Best Plus Size Sleeping Bag guide. It's got the best sizing for big and tall campers, but we also think it's the best option for anyone who wants a sleeping bag as comfortable as their bed.
Big Agnes Echo Park

The Echo Park makes a great basecamp bed. We tested in the Tetons, which are high altitude and cold.
The bag is big, weighing 4 lbs 12 oz, and FireLine synthetic insulation (made from 50% post-consumer recycled content) keeps you warm well into 20 degree nights. Since it is made of synthetic insulation, it stays warm when wet, another benefit to car campers.
-
After long days, we loved climbing into the Echo Park sleeping bag. As a sometimes hot sleeper, I found the double zipper entry to be helpful as it allows for extra ventilation and it provided extra room when I slept on my side.
While roomy, it doesn’t bunch when turning over frequently, and the hand pockets in the top corner of the bag allow for it to be pulled over the shoulders like a comforter in a bed.
-
The Echo Park is part of a Big Agnes sleep system, so the bottom of the bag has a sleeve that is made to join the pad underneath, preventing sliding off of the pad in the middle of the night.
Best Sleeping Bag for Side Sleepers: Nemo Forte Endless Promise
Temperature rating: 20°F (35F also available)
Insulation: Synthetic
Packed size: 9 x 11.5
Weight: 3 lbs 7 oz (men's), 3 lbs 10 oz (women's)
Style: Mummy
What we liked: great value for what you get, made of synthetic insulation, good price for a backpacking sleeping bag, lightweight enough to take backpacking
What we didn’t like: expensive for a camping sleeping bag (but a good deal for a backpacking sleeping bag)
The Nemo Forte Endless Promise is our winner for the warmest and most comfortable sleeping bag for side sleepers. While many side sleepers struggle to stay warm in mummy or rectangular camping sleeping bags, the Forte's SpoonShape doesn't feel restrictive and kept us toasty. The unique shape adds extra room at the elbows and knees to allow for more comfortable side sleeping without the drafts side sleepers experience with more traditionally-shaped bags.
We also like that the Nemo Forte Endless Promise is made of recycled materials and at the end of its life, it can be fully recycled. The goal is to keep gear out of landfills and that's something we can get behind.
Read our full review of Nemo Forte Endless Promise for more details.

The Nemo Forte Endless Promise has a Spoon Shape design on a mummy bag. We found this design to make all the difference. We liked the similar Nemo Jazz 30 (which has a rectangular shape with a mummy hood) but nothing could keep in the warmth like the Forte. Especially for tossers and turners, the Forte kept us feeling cradled without letting drafty spots get cold.
-
The Forte Endless Promise is not only a great camping bag, but a great backpacking sleeping bag.
At 3 lbs 10 oz, you could find lighter bags for backpacking. However, remember that weight and insulating ability are correlated — at 20F, the Nemo Forte can handle most temperatures you should consider going out in as a beginner. It’s the winner of Best Synthetic Sleeping Bag in our Best Backpacking Sleeping Bags and it offers great value for a backpacking sleeping bag.
-
In a world where we've seen sleeping bag prices balloon due to tariffs and increased fuel costs, the NEMO Forte Endless Promise is one sleeping bag where the price has stayed consistent in the past year. We applaud NEMO for keeping this high quality bag affordable.
Best Kids' Camping Sleeping Bag: Kelty Space Cadet
Temperature rating: 30°F (40F also available)
Insulation: Synthetic
Packed size: 10 x 7 x 7
Weight: 1 lb 3 oz.
Style: Mummy
What we liked: warm, reasonably priced, wide age range from 8-20 months and 2-4 T, easy to slip on and off for diaper changes
What we didn't like: some kids may find tight around neck and arms
The Kelty Space Cadet 30 Sleeping Bag, an innovative suit that’s part sleep sack, part sleeping bag, and built specifically designed for kids. It is our favorite kids' sleeping bag in our Camping with Kids Gear List. It is designed to promote safe sleep practices so you can get out camping at an early age with your kids.
The Kelty Space Cadet fits snug around your kids feet and covers them all the way to the tip of their fingers thanks to flap over hand muffs. It features an ultrasoft fleece lining around the neck and promises a comfort rating down to 30 degrees.
Camping with little ones adds a whole new layer of complexity to the sleep system question. Our Camping with Kids Checklist covers kid-specific sleep options like the Kelty Space Cadet sleep suit — plus all the other gear that makes overnight trips with babies and toddlers actually work.
Kelty Space Cadet
Best Mummy Camping Sleeping Bag: EXPED Deep Sleep
Temperature rating: 20°F
Insulation: Synthetic
Packed size: 9.8 x 11
Weight: 3 lbs 1.5 oz.
Style: Mummy
What we liked: value for price, compression sack included, eco-friendly materials, lots of width and length options, lots of temperature options
What we didn't like: mummy can feel constricting compared to other camping bags
The Exped Deep Sleep is a premium-feeling mummy sleeping bag at a budget price. With the Exped DeepSleep, you get all the features you'd expect in a higher-end camping sleeping bag at a price that seems so affordable, you wonder if someone messed up when listing the price. It comes with a compression sack—which usually costs $40 extra—and is compact enough for backpacking and camping. Based on our review of the Exped DeepSleep, we think you'd be hard-pressed to find a sleeping bag that offers a better value.
The mummy shape isn't for every camper and many people prefer this style for backpacking. The shape isn't for everyone, especially folks with bigger bodies. But if you want a mummy bag, you'd be hard-pressed to find a better option than this.
You can read more in our in-depth review of the Exped Deep Sleep sleeping bag.
EXPED Deep Sleep
-
We have been testing the Exped DeepSleep sleeping bag for the past nine months in everything from sub-freezing temperatures in snow storms to balmy summer days. In all, we've spent about 40 nights camping in this bag for this review.
-
We found the sleeping bag temperature rating to be pretty accurate. We had four testers with different body shapes, metabolism rates, and sleeping styles (back vs. side) camp and backpack with the Exped DeepSleep bag. We tested in snow storms in Sequoia National Park and on sub-freezing nights near Yosemite National Park.
-
The Exped DeepSleep sleeping bag has among the most cutting edge sustainability features we've seen in a bag by any outdoor brand. Its entire life cycle takes into account sustainability, from the materials it is made of to the ease of washing to the end of its life. This full-cycle sustainability is really the future of sustainable gear.
The DeepSleep is made entirely from 100% recycled polyester for complete recyclability at end of life. Because it uses a single material construction, it eliminates the mixed-material challenges that most sleeping bags face.
You can read more about this in our Innovations we saw at Outdoor Market Alliance news article.
Other camping sleeping bags we tested
The world of sleeping bags is a big one! Some were pricier and more technical than needed for an introductory 3-season bag, and others may have been missing key advantages of the bags we chose but are still worth considering. Some of these bags follow.
REI Hunkerdown
Temperature rating: 20°F
Insulation: 600-fill down
Packed size: 7.75 x 12.5
Weight: 3 lbs 6.3 oz.
Style: Rectangular
The REI Hunkerdown sleeping bag is a rectangular-shaped sleeping bag designed for comfort and maximum movement. It was a contender for best car camping sleeping bag. We liked that it has lots of size options including wide and long options. It's also made of 100% recycled polyester.
Ultimately, we didn't find this bag as soft and comfortable as other car camping sleeping bags we tested. It also didn't feel as warm as the 20F rating. This is a good option if you are camping in the summer and especially if you can find it on sale during one of REI's big brand sales.
REI Hunkerdown
Temperature rating: -25°F
Insulation: Flannel/ Canvas
Packed size:80 x 36
Weight: 11.7
Style: Rectangular
The Alps Outdoorz Redwood was an award-winning bag on many gear review sites. Rated to -25F, it seems tempting to get this bag if you are a cold sleeper.
However, we find that bags rated to this temperature are overkill for summer. In fact, they can make you sweat and actually feel less comfortable in most conditions than a bag rated to 30F.
As is expected for a bag rated to -25F, it also is not very compact, so storing it for the 3 seasons when you don’t need a -25F degree bag can be cumbersome, especially if you live in a smaller space.
ALPS OutdoorZ Redwood
Temperature rating: 30°F
Insulation: 550-fill down
Packed size: 7.5 x 15
Weight: 2.6
Style: Rectangular
The Kelty Galactic Down is very similar to our overall winner, the Kelty Cosmic (see review above), except with a rectangular shape instead of a mummy shape. But ultimately, when choosing between the two bags, we found the Cosmic to feel warmer. While the Galactic Down is lightweight and compact, customer reviews agree calling the Galactic Down temperature ratings are best suited for summer. The material is soft and it's a comfortable bag, just not as warm as the Cosmic.
Kelty Galactic
Temperature rating: 20°F
Insulation: Synthetic
Packed size: 13 x 29 in.
Weight: 5 lbs. 3 oz
Style: Rectangle (semi-tapered)
The Nemo Jazz is one of the most interesting camping sleeping bags we’ve seen. It was out of stock for several seasons, but was the overall winner of Evo’s Best Sleeping Bags for Camping. It’s designed to brign the comfort of your bed to a camping trip and includes a bedsheet, draft collar, and extra insulation. It also had an integrated pad sleeve so there’s no slipping and sliding around on your camping mattress (you can even roll them up together when you put iut away). Lastly, it has a pillow pocket so your pillow always stays in place.
It has other unique features, including zippers on both sides, a removable interior sheet, a built-in pillow, and a sleeping pad sleeve. With that said, most of those features are easily solved by more custom affordable options (like an independent sleeping bag liner), and at $300, the price was high.
Nemo Jazz
Temperature rating: 30°F
Insulation: Synthetic
Weight: 2 lbs 14 oz (regular)
Style: Rectangle
The Teton Sports Polara 3-in-1 is an alternative to the North Face "One Bag," as is the Coleman All-Weather Multi-Layer. All three of these bags offer a 3-in-1 design for added versatility as the seasons change and you find yourself camping in colder or warmer temperatures.
Unfortunately, both simply lack the quality of The North Face equivalent, weighing more for less insulating power. The Teton Sports Polara is more affordable, but we think it’s worth spending more for the comfort and ease of use of the The North Face One.
Teton Sports Polara 3-in-1
Temperature rating: 20F
Insulation: Synthetic
Weight: 2.7
Style: Mummy
The newly updated Marmot Trestles Eco Elite is a twist on the classic sleeping bag that we've tested and liked for the last few years. The Eco Elite is made of 100% recycled fiber insulation and shell. That means the bag is fully recyclable at the end of its life, similar to the Nemo Endless Promise line but at a fraction of the cost. You can read more about this in our Innovations we saw at Outdoor Market Alliance news article.
Aside from materials, the Trestles features Marmot' wave-construction to improve loft, a stash pocket, anti-snag zipper, and an accurately rated temperature rating of 24 F degrees comfort. We also appreciate how it is available in an X-wide option.
While we liked this bag, we ultimately found similar features in the EXPED Deep Sleep for a more affordable price. Still, we think this is a good camping sleeping bag, especially if you can find it on sale.

What to look for in a sleeping bag for camping
If you decide to look into other bags than the ones we recommend, it may be helpful to keep these tips in mind when researching:
Materials
Insulating ability
Sleeping bags exist primarily to insulate you and keep in the warmth, so you want to know if it will work. Most bags have a “comfort rating” (how cold it can get outside while you still stay warm) and a “survival rating” (how cold it can get outside before you are in danger). This is the single most important thing to know about your bag!
Synthetic insulation? down insulation? flannel or cotton insulation
While the amount of insulation influences how much it can keep you warm, the type of insulation influences how a bag keeps you warm. Flannel is warm but heavy, hard to pack, and holds water like a sponge. Synthetic and down are light enough for backpacking but vary in their ability to insulate. While down tends to be better, it’s useless once a “strand” of down gets wet.
Even a damp down bag is noticeably less warm — a drenched one is ineffective. New technologies, like “dridown,” coat the strands of down in a waterproof chemical — those have more resistance, though they should still stay dry. When I say “strands,” imagine a thin feather (down is technically a unique type of feather closer to the bird's skin, under the layer of features you typically see).
Right for the job?
There are very few “bad” materials, but sometimes materials are not the best for the job at hand — we’ll explain what each bag is (and isn’t) good at.
Is it sustainable?
Good materials should be durable enough to last and, ideally, to be recycled or responsibly disposed of.
Comfort & effectiveness
Shape
Rectangular, semi-rectangular, or the “mummy” bag shapes vary, but the biggest differences are how tight the bag is around the feet and head. This impacts comfort by reducing dead air space — such as in a mummy bag that runs closer to the body. It can also shape the insulating effectiveness. Mummy bags tend to be better at insulating because they generally have fewer draft spots. Many people find that a rectangular sleeping bag shape mimics the comfort of blankets on a bed at home.
Zipper adjustability
To assess adjustability, we asked questions like: can it zip from both sides, letting you cool your feet during the night? Can you tighten the hood around your face to lose less heat? Can you add or take away layers or zip it to another bag to create a double bag?
Design
We asked questions like: does it have a “baffle” — a pocket of extra insulation designed to lay over zippers, shoulders, or other places where heat tends to leak? Are the seams sewn with insulation in them to stop heat from escaping? Design features like this make a big difference in warmth on cold nights.
Getting in and out
Trust us — there is nothing worse than being groggy and realizing you can’t find the zipper and get out of your bag. Whether you need to pee or just want to see the stars, the ability to get in and out makes a big difference in how enjoyable your bag is.
Size and Weight
Size
Size is important both for comfort and effectiveness. A bag that is too big won’t “heat up” as your body releases heat, and therefore can’t keep you as warm. Too small, and you compress the insulated air that keeps you warm- and you’ll cool down. Plus, you want room to maneuver (especially if, like me, you roll in your sleep).
You also always want to store your bag “fully lofted” (i.e., not stuffed in its stuff sack), so size matters when you think about where you’ll keep it when you aren’t camping.
Packed size
Packed size matters when you either have a lot of camping gear competing (like on a family car trip) or limited space (backpacking). In some cases, packed size is a deal breaker, though for others it may not matter as much.
Weight
Weight only matters if you plan to carry your bag a lot — but if you want to get into backpacking, a light bag makes a world of difference.
Other features
While not universally important, you may want to consider whether a bag has pockets, how noisy it is when you move, or other unique features about each bag.
Price
You can find bags across many price points — from $40 to $50 (or even lower) for a bag that is basically a blanket with a zipper to $2,000 for what is a cold-weather shelter. We tried to find you the best bang for your buck (while steering away from the most expensive performance bags). As a result, most of the bags we looked are under $300.
How to Choose a Sleeping Bag for Camping
Even on dry sunny days it is best to keep sleeping bags on a pad and off the ground.
Sleeping bags are arguably the most critical part of your “shelter kit” while camping. They make the difference between a good night’s sleep and a bad one. While you can camp without a tent, you almost always need a sleeping bag to get through the night.
The concept is pretty simple: once you’re inside the bag, the air held still by insulation catches and retains body heat to keep you warm.
A huge range of bag shapes, fabrics, insulation materials, and sizes are used to achieve this simple feat, which is where picking the right bag for you can get tricky. We’re here to make that choice easy for you. The first step to choosing your ideal bag is figuring out just how you need to use it.
What kind of sleeping bag do I need for camping?
Outdoor equipment is technology; like any other technology, it is designed to meet different needs. In this article, we will focus on casual outdoor camping sleeping bags. These are great for car camping (or with rafts and boats) when weight and size are less important than warmth and comfort.
However, the bags we include still cover many different uses. For example, there are 3-season bags you might use for “casual” camping — for warm summer nights, inside a rustic heated cabin, on a kids sleepover, or for a guest staying over.
What type of sleeping bag do I need for winter camping?
Although this guide primarily focuses on 3-season sleeping bags for summer camping, it's worth noting if you're winter camping, you'll want a dedicated winter sleeping bag. These are designed for extreme cold, but you won't need that much additional warmth on a warm night. The sleeping bag insulation that is crucial when temperatures dip below freezing can be uncomfortable during summer camping. The sleeping bag temperature rating is the best indicator of whether your sleeping bag is 3-season or a cold-weather sleeping bag.
How do I choose a sleeping bag based on the climate where I'm camp?
If you primarily camp in dry climates, go with down. If you usually camp in wet climates or are a beginner, go with synthetic insulation. This is because down, once wet, isn’t usable (see our “materials” section above for more on that). If you primarily camp inside (in cabins, sleepovers, etc.) then consider flannel or cotton bags.
What camping sleeping bag do I need for the temperature where I am camping?
Most bags share their survival rating, which is how low the temperature can go while keeping you safe. That’s very different from a comfort rating, which is how low the temperature can go while keeping you (you guessed it) comfortable. I’d aim for a bag rated 10 degrees warmer than the average temperature where you camp.
How should a camping sleeping bag fit?
Get a size that leaves you some room to wiggle but is still close to your body. The more empty space in your bag, the longer it takes for your body to heat the air and trap warmth inside. Bigger bags can actually make you colder because of this quirk of insulation. Beyond that, it’s ultimately a matter of comfort.
What shape of camping sleeping bag should I choose?
Mummy bags tend to be lighter for the same amount of material, making them a better option for backpacking. In addition, because they run closer to the body, they do a better job of trapping warmth. A mummy sleeping bag is a good choice for cold sleepers, particularly with cold feet. A rectangular sleeping bag will allow for more room to maneuver, and some find them more comfortable or easier to move around in. While some couples opt for a double sleeping bag, in our experience, it is easy for drafts to form. As a result, a double sleeping bag doesn't often keep both campers warm, so we didn't include one in this guide.
Camping sleeping bags vs. backpacking sleeping bags
The short version: camping bags prioritize comfort, backpacking bags prioritize weight. Both keep you warm, but the tradeoffs between them are real and worth understanding before you buy.
A camping sleeping bag is built for car camping, where you're not carrying it more than a few steps from your trunk. That means manufacturers can use bulkier synthetic insulation, softer interior fabrics, and roomier shapes without worrying about how it compresses or how much it weighs. The result is something that feels more like your bed at home, which is exactly what most car campers want.
A backpacking sleeping bag has to earn its place in your pack. That means down insulation or high-end synthetics that pack small and weigh little, a tighter mummy shape that reduces dead air space, and none of the comfort extras. Some people find the fit restrictive. Others don't mind once they realize how much warmer a close-fitting bag keeps them.
The practical difference is significant. I've tested bags on both ends of the spectrum, from plush rectangular camping bags that wouldn't fit in a standard backpack to ultralight mummy bags that compress to the size of a Nalgene. Neither is better in all situations, they're just built for different ones.
If you primarily camp from a car but want something that can occasionally pull double duty on an overnight hike, a crossover bag is worth considering. The Nemo Disco Endless Promise reviewed above is a good example: it has the roomy SpoonShape that side sleepers love but packs light enough for a short backpacking trip. Similarly, the ExPed DeepSleep is a synthetic bag light enough to work in either context. For bags dedicated to backpacking, see our Best Backpacking Sleeping Bags guide.

How to Care for a Camping Sleeping Bag
Sleeping bags are easier to take care of than most people think, but a few habits make a real difference in how long they last.
Store it uncompressed. The single most important thing you can do for your sleeping bag is keep it out of its stuff sack between trips. Compressed insulation, whether down or synthetic, loses loft over time. A bag stored loose on a shelf or in a large breathable storage sack will loft up faster and keep you warmer for years longer than one that lives stuffed in a corner.
Wash it as little as possible. Every wash puts stress on the insulation and the shell fabric. The best way to reduce how often you need to wash your bag is to keep it clean in the first place. Sleep in a base layer to keep body oil and sweat off the interior. A sleeping bag liner goes a long way here too. You wash the liner regularly and the bag almost never. Air the bag out unzipped after every trip before putting it away.
When you do wash it, do it right. Down and synthetic bags need different products and different treatment, so check the manufacturer's instructions first. One thing I've learned from washing a lot of bags: use an industrial machine at a laundromat rather than a home washer. The agitator column in most home machines is hard on sleeping bags and can damage the baffles. Always use a cleaner designed for technical outdoor gear, sold as either Down Wash or Synthetic Tech Wash. Our How to Wash a Down Sleeping Bag guide covers the full process step by step.
Keep it off the ground. Most exterior damage comes from direct contact with dirt, rocks, and sharp debris. Keep the bag on a pad or in a tent rather than directly on the ground, and be careful around campfire sparks, which can burn small holes in the shell fabric faster than you'd expect.
Handle the zipper carefully. The zipper is the part most likely to fail and the hardest to fix. Use two hands when zipping and unzipping, especially in cold weather when the teeth are stiff. If the zipper sticks, don't force it. See our How to Repair a Zipper on Outdoor Gear guide for fixes. Higher-end bags from brands like Nemo use anti-snag zippers that handle this better than most.
Repair small damage early. Rips and tears in the shell are usually easy to fix if you catch them before they spread. I recommend Annie Getchell's Essential Outdoor Gear Manual for anyone who wants to learn how to repair their own gear properly.
How to Sleep Outside Comfortably
The author using sleeping bags in a quinzhee, a type of snow shelter, to get through -50 degree nights
One thing I wish I’d learned sooner is that sleeping is a skill. Because we all do it so often, it can be easy to think of it as something that just happens. But when I started camping and guiding professionally, I quickly learned that you can get better at it over time. Practice helps, as does experimentation.
It helps to start slow. Especially when you are a first-time camper, a sleeping bag can feel tight and restrictive relative to blankets. Consider using it first on your mattress at home, so your body gets used to it.

how to stay warm while camping
The biggest thing to remember is that sleeping bags don’t create their own heat — it all has to come from you. If you go into a bag already cold, you can expect to stay cold all night. If you go in already warm, on the other hand, you are more likely to stay warm. A few laps around the tent (or other exercise) can help heat your body, and therefore, the bag, before bed.
Fully lofted bags keep you considerably warmer, but it takes time to get there — make sure you unpack your bag a few hours before use if you can!
There are literally hundreds of tips for staying warm in a bag, but here are those I’ve found I’ve relied on most when helping my students:
Eat food! Your body needs to metabolize to keep kicking off heat. Fat is best for long cold nights. Keep snacks in your bag (unless you are in bear country) to “refuel” during the night.
Fill dead space! Your body heats air to stay warm, but air only stays warm if it is still. Insulation traps air to keep it from moving. So any big open spaces around your body allow for airflow. Put some clothes there to trap more warm air (but not too tight — compressed insulation doesn’t help!).
Get cold during the night? Do sit-ups in your bag. Or try to swap your socks from one foot to the other — the movement required almost always heats you up. Just try to avoid rolling over and compressing the insulation flat — you’ll lose all the heat you already stored. Once your bag is puffy, keep it that way all night!
Still cold? A hot water bottle between your legs will heat your blood, and your blood flow heats your body. If it’s too hot to touch, put your sock around it so you can (only use Nalgenes or metal that won’t bend from the heat).
How to not overheat while camping
Bags are designed to trap warmth — so the best way to stay cool is just to use less of your sleeping bag.
Sorta warm? Unzip the bag around your feet to get more airflow.
Pretty warm? Unzip the bag, and use it as a blanket above you, not below you
Totally warm? Unzip the bag, and leave it open to your side — this lets a lot of air out
Figure out what zipper length works for you, especially once you add a sleeping pad into the mix — and remember that it will also change based on conditions. I use an unzipped zero-degree bag well into early summer. All winter I zip it up, and on the warmest days of summer, I just change to a lighter bag.
FAQ
-
The temperature rating for your sleeping bag should be based on the conditions you usually camp in, since bags come in a wide variety of temperature ratings from sub-freezing to 40 degrees or more. A good range for most car camping is somewhere between 20 and 40 degrees. If you are winter camping or in cold temperatures often, look for a bag with a lower temperature rating, and if you’re usually camping in hot climates opt for something closer to 40 degrees or so.
-
Down insulated sleeping bags are made with duck or goose down feathers while synthetic bags are filled with polyester and other synthetic materials for insulation. The advantages to down are that it’s lighter, loftier, and more packable than synthetic options, but unless it’s treated with a hydrophobic coating, down does not perform as well in wet climates.
Down is also almost always more expensive than synthetic insulation. Synthetic insulation is easier to care for, less expensive, and often performs better in wet conditions than down, though it’s heavier and tends not to pack quite as small. Synthetic bags are often a good choice for car camping because weight and packability aren’t as much of a priority as they are with backpacking, and because synthetic bags are more affordable and easier to care for.
Fill power is a standard metric for down. It measures “fluffiness,” or how much volume a specific weight of down fills (typically cubic inches per ounce). So 550 fill, as found in the Kelty Cosmic Down, means that an ounce of down could fill 550 cubic inches. More space means more air trapped, which means more insulating power. Higher fill (800 is typical high-end down) is warmer per ounce, but a lot of 550 fill is warmer than only some 800 fill.
-
You’ll want to consider both length and width when choosing a sleeping bag. Compare the measurements of the bag to your body. You want to fit into the bag comfortably with it covering up to your shoulders and the hood (if there is one) reaching the top of your head without being too snug. A little extra space can make the bag more comfortable, but a bag that is way too large often won’t do as good of a job insulating you as one that’s sized properly.
-
Mummy shaped sleeping bags are a common choice for campers and backpackers because of their warmth and their packable nature. They are a better choice when space and weight is a concern, but for car camping they’re not always necessary. If you enjoy feeling swaddled in your bag, a mummy bag may be the most comfortable. But if you prefer to stretch out, a different style of bag may be better for you.
-
Children can slip into an adult sleeping bag, but it’s not ideal and not likely to keep them very warm. If you want your kid to have a good time camping and get good sleep in the tent, you’ll be better off with a bag that fits them properly and keeps them toasty.
-
Sleeping bag liners are not necessary, but they can help you have a more comfortable night of sleep. Some advantages to sleeping bag liners is that they add warmth, so if you sleep cold it might be a good option. They’re also typically easier to clean than the sleeping bag itself, so you can treat it almost like a sheet and wash it after your trip if that’s something that is important to you.
-
Some sleeping bags can be zipped together, but this is not the case for all bags. It’s best to check the details and instructions before doing this to avoid any unfortunate zipper issues.
-
Most summer camping sleeping bags fall somewhere in the range of 20 to 40 degrees fahrenheit. Think about the nighttime lows where you camp most often and base your decision on that. It’s best to err on the side of a warmer bag (unless you’re a particularly hot sleeper) because it’s easier to vent your bag than it is to get extra warmth when it gets chilly.
-
Winter camping sleeping bags should have a temperature rating well below freezing, and a 20 degree bag is often the upper limit of what is possibly warm enough. For most winter camping, opt for a bag with a rating around 0 or 10 degrees, but if you are sleeping in extreme winter environments, a warmer bag that has a temperature rating below 0 may be necessary.
-
If you camp primarily in the summer, then a 3-season bag is probably sufficient. But if you like to sleep outside no matter the time of year, you may want to consider a 4-season bag. However, bags that work well in summer are often not warm enough for winter conditions, and winter bags often turn into saunas in the summertime. If you camp in all four seasons often, having separate bags for cold weather and warm weather might be the best option.
-
When we teach people to camp at BOAT, we talk about how you go out with needs (like sleeping, or staying out of the elements) and systems to meet those needs.
Sleeping bags are part of your “sleep system” (which gets you through the night) as well as your “shelter system” (which keeps you warm and dry). Your sleeping bag is rarely complete without a camping mattress or a camping tent.
Pay extra attention to your sleeping pad. Whenever you sleep on a sleeping bag, you compress the insulation. Compressed insulation cannot hold heat and won’t keep you warm — so a pad underneath you is a critical part of most sleep systems. See our Best Camping Mattresses guide for our recommendations or if you want something lightweight, check out our Best Backpacking Sleeping Pads guide.
For those seeking maximum comfort and elevation off the ground, camping cots offer an excellent alternative to sleeping pads. See our Best Camping Cots guide for top recommendations.

Some people like other accessories to complete their sleep and shelter systems — inflatable pillows, solar lanterns for the tent, or (my favorite) — a pair of “sleep socks.” These are warm, comfortable, cozy socks that never leave my sleeping bag, guaranteeing I always have a dry pair overnight. Then, of course, I change out of my “sleep socks” into “hiking” socks in the morning.
We get into more details on what you need to go camping in our camping gear checklist. As far as camp kitchen goes, we have a separate article with a Camp Kitchen Essentials Checklist.
If you happen to be going camping in winter, we recommend going camping in milder weather first to get a hang of it. See our Winter Camping Gear Checklist for what gear you can pick up to extend your summer camping gear into cooler weather.
How we Researched & Tested
Testing camping sleeping bags side-by-side for this guide.
Sleeping bags can lose their ability to insulate over time. In addition, both design and materials also evolve as technology improves. Because of that, we focused on newer models. At the same time, you can only get so creative with sleeping bag design. You will see most of our contenders came from trusted companies that have made good bags for years. Our recommendations come from our own experience with the brands and online reviews, including those from REI.
We also did our own testing — both in damp, spring Wisconsin weather and (when we needed to get below ~50 degrees) inside a large freezer to test sub-32 degree weather. We focused on 3-season bags, waiting for the winter to test models that can get you through a winter night.
We tested with a few different people, including both self-identified “warm sleepers” and “cold sleepers.”
Our key criteria were (1) materials and (2) comfort, as well as (3) insulating ability. If a bag can’t keep you warm and comfortable all night long, it’s simply not doing the job.
Our secondary criteria focused on ease-of-use. We looked at things like (4) ease of entry and exit, (5) shape, (6) adjustability, and (7) price. The best bag is one you feel good in not just when you are awake but also when you’re sleeping — even if you roll, move, or have to get out to use the bathroom. Finally, we considered (8) packed size and weight. While you may not be carrying it for miles, you want to be able to get it wherever you are going!
