Your number one defense against the elements, your companion on every camping trip: your sleeping bag. You can’t really go camping without some quality sleeping bags, which is why we’ve pulled out the thirteen best sleeping bags on the market, and talk about what makes them tick. We’re looking at lightweight, compact solutions that keep your total carry weight low, and have you feeling immense peace of mind when it comes to temperature control, protection, and comfort. We won’t keep you any longer: let’s get to the good stuff.
The Best Sleeping Bag
Coleman is one of the names we’ve come to trust and admire for outdoor gear, and they didn’t drop the ball on this sleeping bag. You get a 40-60 F temperature rating, partially thanks to the comfortable brushed interior. If you have dry skin, it might snag along it but is otherwise soft and comfortable to help you sleep through the night. We’re also big fans of the fact that it compresses and rolls up like a dream, so packing up the morning after isn’t even a concern.
When it comes to the rain, this is going to soak right through. There’s no water resistance on the exterior, which also comes with an additional issue. You’d think that it might make it easier to clean, but that’s not the case. The brushed interior holds onto dirt and dust, which is why we recommend following the sleeping bag care guide below. Apart from that, Coleman’s Sunridge sleeping bag is fantastically comfortable, lightweight, and might be the most inexpensive quality sleeping bag you’ll ever own. Make sure you also check our guide to the best large camping tents for more great camping products.

Includes Coleman’s ZipPlow, which prevents your materials from getting snagged
Viable for 40-60 F camping conditions
Brushed interior is insanely warm
Simple no-roll method for quick packing
Relatively zero water resistance
Difficult to clean properly
Coleman’s solution for zero degrees camping is absolutely fantastic and helps to open up your camping schedule well into the winter. The main draw to this sleeping bag is the insane temperature rating, but unlike most bags in this range, it’s not going to cost you an arm and a leg to acquire. Coleman’s zero degrees mummy bag is also designed for up to six-foot-two occupants, though thanks to the insulated foot box on the bottom, you could stretch an extra inch or two if you really needed.
They’re good, but not almighty: compressing this bag is going to be a nightmare, which is why many users agree that it’s best for car camping or cabin camping. You can absolutely roll this up underneath your external frame backpack if you wish, but it’s going to be tricky. As a result of the plush fabric, cleaning is going to be a chore as well. If you’re using the HE wash-and-dry method, you’ll have to toss it in the dryer no less than two times (though we had to run it for three). Quality build with amazing insulation, but at a cost.

Teton is a major name, and we tend to give larger brands a more detailed look just to ensure that they really are living up to par. Teton blew us away, and by going with them, you get locked into their limited lifetime warranty guarantee and get access to their killer customer support. But about the sleeping bag itself: you get a comfortable poly flannel liner that’s comfortable to a fault. It’s easy to get tangled up in it but also cradles you to help you sleep like a baby.
Teton Sports Celsius Sleeping Bag is also rated to handle temperatures as low as 20 F, giving you a longer camping season than that old bag you’ve been using. We’re not crazy about the weight when this is rolled up, resting at about seven pounds, but it still beats many heavier options out there. A few points we’d like to touch on include the half-circle hood that acts as a pillow between you, and whatever ground you’ve decided to camp on for the night. You can also choose to have the zipper on a side that’s more accessible to you, regardless of your dominant hand orientation.
Available in alternate zipper sides
Average temperature range of 20-30 F

- Weight7.05 pounds
Includes draft tubes to keep cold air out

Coleman tries to keep things as inexpensive as possible, which was their goal when designing the Biscayne sleeping bag. So the price is great, and most of the features hold up well, but we have to talk about their love of poly interiors. Poly isn’t bad, but the quality of this specific sleeping bag’s interior gets caught on your skin fairly easily. If you sleep with socks and a long shirt, it’ll be great. You get Coleman’s standard temperature rating, letting you camp out in 40 F weather with no problem.
Perhaps our favorite feature is the roll control and quick cord aspect, which not only makes this super easy to pack up but unrolling it is like a dream come true. Fast deployment, lightweight build, but definitely a lot thinner than we would have liked. If you’re bringing a separate liner or you’re unaffected by a bit of rugged mother nature beneath your back, you’ll be good to go. This sleeping bag is built with the big and tall in mind: plenty of width for comfort, and a total of six-foot-four on the length.

ZipPlow technology ensures fabrics don’t get jammed in the zipper

Teton’s a good brand, always trying to do right by their customers, which is why they include their limited lifetime warranty on every sleeping bag (at least the ones we’ve seen and used). They put that same idea into the design, ensuring that you’ll never have to call upon that warranty. Part of this bag’s durability comes down to the abrasion-resistant taffeta shell, which also provides a bit of water repelling attribute as well.
Comfortable liner, roomy, and over seven feet tall. Fahrenheit Mammoth is great but fell flat when it comes to the value. Make no mistake, this bag will last you for ages, but at a higher upfront cost than the other bags, we’ve reviewed so far. Apart from that, even though we expect double sleeping bags to be heavy, this one’s definitely going to weigh down your pack by a great deal. The good news is that it won’t take up much storage space because Teton includes a compression pouch that works wonders.

Kelty adds some more diversity to this list with their Cosmic bag. We’re big fans of how unbelievably lightweight these bags are, even if you opt for the longer versions. Minimalist campers will be in bliss, especially when you consider just how durable the exterior is. Crafted out of water repellent, durable 50D ripstop polyester, nothing’s going to get through this bag. We were a bit miffed about the sorely lacking quality of the zippers though, which really didn’t live up to the Kelty name.
The only other major gripe is that the interior will catch on just about any area of your feet, so sleep with socks on. That interior does boast their DriDown insulation, which is designed to wick away sweat and keep you cooler throughout your camping trip. Compression and storage is a cakewalk, and rolling this out isn’t going to take you more than ten seconds. The big up is protection and portability, built to a standard that other brands just haven’t been able to match.

Don’t lie, you want to jump into this sleeping bag rights now. Gideon creates Extreme Waterproof Double Sleeping Bag with a durable 210T polyester exterior, which not only keeps it durable but also extremely comfortable. You’ll notice the unique platform stitching pattern on the top, which helps to hug your body while two of you are stuffed into this sleeping bag. Comfort is on point, but the interior lining has a habit of causing a lot of uncomfortable static electricity. You’ll get two pop-up pillows included with this sleeping bag, adding to neck support at night.
While they’re not full replacements for camping pillows, every little bit helps. Gideon does an excellent job of keeping things excellently waterproof, but you won’t be bringing this along on any winter camping trips. The 3D synthetic interior insulation is good, but it’s not going to protect you against harsh, cold winds. Part of that is related to the price: it’s wildly affordable and comfortable as can be, so long as you use it during the right season. Last but not least, despite the filling being synthetic, this compresses down extremely well.

Marmot made a weirdly awesome mummy-style sleeping bag here. First and foremost, it’s lightweight and optimal for minimalist campers looking for a better, low temperature solution. It’s just over four pounds in total and can hold off the cold as low as 15 F for you four-season campers out there. The major issue we found is that the zipper not only has a short length but is fairly weak and often gets stuck. The zipper track is plastic instead of metal, and we all know how easy those are to damage.
Apart from that, the only other issue is with the mouth flap. Sleeping for six to eight hours builds up a lot of moisture on them from breathing, which is a bit of a disappointment since the rest of the interior is fairly moisture resistant. You’ll still be protected from the 100% polyester construction, and we have to give credit to their unique footbox design. Marmot Trestles 15 Mummy Sleeping Bag is crafted with an anatomically correct shape in mind, so you’ll prevent heat loss through the bottom of your sleeping bag.

Does it look like an actual envelope? Kind of. AmazonBasics is known to make inexpensive versions of higher grade products (sometimes at a loss to them, but you and I benefit from it), and their envelope sleeping bag is no exception. This simple single sleeping bag comes with a fully washable interior and exterior, making it super simple to throw in the wash and forget about it. That’s because the filling is synthetic, which attributes to its lightweight build and compressibility. The problems come in where you don’t expect.
For one, AmazonBasics Envelope Sleeping Bag is inexpensive (not a bad thing), but they had to cut corners on the size. It can fit up to 5’11” gents, but beyond that, you’d be scrunching up your knees. Considering that over 120 million men are six feet tall or more, this sleeping bag only works if you fit the height requirement. On top of that, they give a range of 20-40 F for heat retention, which is unusual. That’s because they rely on you to clothe yourself appropriately to get the full 20 F benefits. While it has its flaws, it’s one of the most inexpensive sleeping bags you’ll ever own, and included a one-year limited warranty on just about everything.

If you’re sick and tired of your sleeping bag not supplying you with enough heat, Snugpak is about to change that. The number one reason why minimalist campers are flipping out over Softie Elite sleeping bag is that you can sit in temperatures as low as -4 F. That’s thanks to a mixture of the interior heat plate that reflects your own body heat back towards you while resisting external cold, and the extremely snug design. The only problem is that if you’re minorly claustrophobic, this bag won’t be a good fit for you, because we mean it’s snug.
Our only other gripe is the zipper quality, which seems to be a trend with sleeping bags as of late. We wished there were most brands using YKK zippers, but instead, these are fairly standard quality and easy to damage if you move too quickly. It snags fairly easy, but oddly enough the zipper on your chest pocket doesn’t. That extra storage is great for EDC items or a tactical flashlight and compresses along with the rest of this ultralight sleeping bag. Just over five pounds for this level of coverage? It’s unheard of, and yet here it is in front of you.

We keep dropping lower into the sub-zero range. Browning Camping Kenai Mummy Sleeping Bag can take you as low as -20 F, and keep you warm thanks to a few additional features. Beyond the two-ply internal filling, there’s also (finally) a durable zipper on a low-temp sleeping bag, one that opens up completely and helps to retain your body temperature. That’s built into the 210T nylon exterior, making this extremely durable in all situations, but not exactly the easiest to clean.
The size and weight of this are the two main issues. It’s just under nine pounds, and while you can understand why it weighs that much, it’s a less viable option for solo camping. Apart from that, compression is a chore, so you’ll have less room in your pack for other items. What you will get is the added support of the ergonomic footbox design, contouring to your anatomy better than square-bottomed sleeping bags. While that makes it a little snug, you’ll also get a double-ply chest cushion area to keep your core temperature in check at all times. Excellent for four-season campers, not the best for minimalists.

Going ultralight this winter trip? It’s not an easy task, but Slumberjack makes it a little bit easier. At just a touch bit over six pounds, this ultralight sleeping bag keeps you safe against -20 F conditions. One of the biggest complaints that we often have with mummy style sleeping bags are the zippers, but this two-sided zipper travels all the way down to the footbox. Now with that insulation, you will run into one problem. Since this is made with synthetic material, twisting and turning in different angles can allow cold spots to occur.
Big and tall gentlemen will also run into an issue because Slumberjack designed Boundary Sleeping Bag for a more slender frame. The height is on-point, and while a sleeping bag of this caliber is usually snug, theirs is a bit too tight if you don’t fit into an ideal weight bracket. It’s lightweight and warm, but it’s also super simple to clean. Thanks to the all polyester exterior construction and the dual zippers, it’s easy to open this up and manually clean it out, effectively preparing it for your next trip.

Last but not least, there’s an old Colorado company that’s devising Big Agnes Spike Lake, a superior sleeping bags. Built with DownTek treated down filling, this sleeping bag is insanely lightweight at just under three pounds, as well as comfortable as can be. Down filling provides superior relaxation when you slip into your bag, but while we’re on that subject the footbox is fairly snug for your feet and toes. This sleeping bag is designed to contour to, and hug your body to keep your temperature exactly where it needs to be.
The temperature rating lets you sleep in conditions as low as 25 F, but for the price of this sleeping bag, we were expecting more. They make up for it and justify the price tag with the ultra compressible design that takes up an extremely small space in your backpack. If you’re an ultralight or minimalist camper, this will keep you in three-season warmth, while being very easy to keep clean thanks to the long zippers.

Sleeping Bag Buying Guide and FAQ
We wanted to find the best sleeping bags, and that’s just what we did. Whether you’re a minimalist who needs a lightweight sleeping bag, or a comfort king that’s all about max relaxation in the outdoors, there’s something here for you. We’re about to break down every component that makes up a good sleeping bag, show you how we devised this list, and discuss your burning questions centered around sleeping bags.
How We Chose Our Selection Of Sleeping Bags
Brand - There are a lot of excellent camping and hiking companies out there that operate on the promise of low costs, and you can absolutely find some great sleeping bags for cheap. When you get into big brands, that’s when you can encounter inflated prices. When you go with a big name brand, it’s because they have a track record for providing consistent support and comfort, and there’s nothing wrong with that.
Reviews - User reviews help us to break down our list before testing these products for ourselves. You can usually find a lot of helpful information on three and four-star reviews that provide proper insight without appearing biased. Steer clear of reviews from first-time campers, as they tend to run into issues that have clear solutions that don’t usually pertain to the sleeping bag or camping product in question.
Price - Price will always be a dominant decision-maker during any purchase. Your sleeping bag is one of your most essential pieces of gear in the outdoors, so you don’t want to skimp on it. We factored pricing into this list, giving you a mix of inexpensive and premium selections, each with their added benefits. You can get effective sleeping bags for a low price, but if you want that to be accompanied with the first-class comfort, that’s when you notice price hikes.
Consider These Points With Sleeping Bags
Temperature Rating - Temperature ratings are why you choose a sleeping bag over a blanket and a night under the stars. If you’re a three-season camper like most of us are, then you know how difficult it can be to stay warm in frigid conditions. Your temperature rating should sustain a minimum of 40 F for summer camping and those unexpected cold nights, and down to 20 F for three-season camping.
Length - Sleeping bags are not a one-size-fits-all solution. You’ll need one that’s within 1-2” longer than your overall height (to account for shell measurements). You want a sleeping bag that’s snug, but not constricting. If you’re 6’2”, get a sleeping bag that’s up to 6’4:”, and so on.
Width - Length and width don’t always correlate. You can find plenty of sleeping bags that are long, but feel tight on the sides. Getting a bag that matches your body type is imperative to ensuring the temperature rating sustains your body heat. If there’s too much space, you won’t be able to warm up all of the filling material.
Cleaning - The better your temperature rating, the most comfortable you’re going to be. But the better that rating, the more likely you are to sweat in your sleeping bag, and it can get funky. Look for bags that are easy to clean, based on accessibility (zipper lengths, which we’ll talk about in a minute), the shell and liner material, and if they’re reversible or not. Either way you’ll have to clean any sleeping bag you get, so don’t make it a lengthy chore.
Warmth - There are actual warmth ratings on most sleeping bags. It gets complex, but what you8 basically want to look for is a sleeping bag with gap coverage, tight hoods and insulated zippers. If your sleeping bag filling can keep you warm in 20 F weather, that’s great, but just make sure the metal zipper isn’t going to conduct the cold and let in a draft. For this, we often turn to user reviews to determine what the best option is.
Down vs. Synthetic - This can come down to preference, but generally speaking, down is more comfortable and lightweight for three-season camping. When you get into puffy sleeping bags, synthetic can go into extremely low temperatures (we’re talking single digits and subzero temps), but at a very high cost.; It comes down to what you need it for, but if you’re someone who can’t stand stuffy, bulky sleeping bags, we’re going to recommend going with down filling.
Zipper Lengths - While this seems like an arbitrary feature, nobody wants to find out that their sleeping bag only opens up slightly, and doesn’t allow full access. Cheaply-made sleeping bags are notorious of adding a short zipper, so you end up wedging your legs in before trying to wriggle down, and somehow find comfort. It never works; you need a long zipper to allow better access.
Water Repellent Rating - It gets tricky when you want a sleeping bag that has it all. Since you’ll usually be in a tent, many manufacturers don’t put a high water resistance rating on their sleeping bags. At best, you’ll find median-priced models with a low IP/IPX rating that help rain bead up and roll off, but won’t do you any favors if you wake up in a puddle or submerge your sleeping bag completely.
Storage - How much space is it going to take up in or on your backpack? You want to keep as much storage space open as possible for things like your EDC kit, survival tools, and camping food. If you’re placing your sleeping bag into its sleeve (most usually come with a nylon carrying case), know that they compress your sleeping bag fairly well to optimize your carry weight and storage space.
Types Of Sleeping Bags
Single - You’ll see single sleeping bags more often than you’ll see any other type. Designed for one-person use, these are traditionally lightweight and easy to store. You’ll find a lot of down sleeping bags with excellent compressibility, allowing you to stash it in your backpack without taking up a ton of space. Single sleeping bags are best for ultralight travel and minimalist campers.
Double - Bringing the wife along? Double sleeping bags generally offer more insulation support and have a comfortable pillow head area to remain comfortable. The only major flaw with double sleeping bags is that you have two people shifting and turning, so hoods become less effective. Some double sleeping bags can break off into two separate sleeping bags, which can help[ save on backpack storage.
Mummy - Just like actual mummies, you’re cocooned in your sleeping bag. These have hoods that cover most of your face, giving you maximum insulation benefits. Mummy sleeping bags usually have much higher temperature ratings and use down filling in their hoods to create a more comfortable experience. If you aren’t bringing a camping pillow along, you’ll still have plenty of comforts.
Wearable - Ever lounge around in a pair of sweatpants all day? That’s what it feels like wearing one of these sleeping bags. They usually have cutoffs at the ankles and hands and may include hoods. These tend to be a little less comfortable, but if you’re someone who hates feeling constricted in a sleeping bag, this could be an excellent option for you. Keep in mind, you'll mostly see these for two-season use, though some brands are viable for winter use as well.
Sleeping Bag FAQ
Q: Are Down Sleeping Bags Better Than Synthetic?
A: There are pros and cons to each, but generally down sleeping bags are superior to the synthetic filling. The first problem with synthetic filling is that it doesn’t compress the same way that down filling does, making it harder to effectively store in your backpack. Even if you’re hooking it underneath your external frame backpack, you still want a compact sleeping bag so it isn’t poking out on either side.
Synthetic does tend to last longer, but often doesn’t offer the same heat retention capabilities, unless you get into four-season sleeping bags. Down feels a lot more natural (you know, because it is) when you’re actually nestled in your sleeping bag. That makes it far more comfortable and easy to fall asleep in. It ultimately comes down to choice, but if you find it hard to sleep at night or you prefer softer bedding (while still being sturdy on the hard ground), then down filling is best.
Q: How do I Choose a Sleeping Bags for Backpacking?
A: We’ve laid out what you should be looking for in a sleeping bag, but that advice can appear arbitrary if you’re going into a specific wilderness setting. While we can’t know every which way a sleeping bag is going to be used, there are a few rules you should follow for backpacking.
First and foremost, you never know what mother nature is going to have in store. Get a waterproof sleeping bag (and sleep in an appropriate area) to keep the rain and rising water at bay. For backpacking, you should also stick to, at the very least, 3 season sleeping bag models. Temperatures can drop unexpectedly, and especially with the current weather trends of the last decade, forecasts can be off. 3 season bags are designed for heat retention even in adverse situations, so if you find yourself in a less-than-ideal predicament, at least you won’t have to worry about keeping warm.
No two backpacking sleeping bag brands build theirs the same way, and one of the most important aspects of picking the right bag for backpacking is closely monitoring the weight. You’ve got enough essentials to bring along that are going to weigh your backpack down, so sticking with a lightweight backpack will reduce fatigue, and also help maximize storage space.
Q: Do Sleeping Bags Lose Their Warmth Over Time?
A: It all depends on the filling material. It doesn’t matter if it’s a double sleeping bag or a single, down filling can lose its loft as time marches on. You should be caring for your hiking sleeping bag properly, such as practicing proper cleaning habits that we’ll discuss in the next question.
Synthetic filling is much more resistant to the test of time and harsher cleaning practices. Because it’s much harder to separate after it’s been molded into the shell, manual fluffing isn’t required, and therefore you don’t alter the shape of the filling. You can still lose worth in your synthetic bag if you aren’t careful, but it’s less prone to heat loss as a general rule.
Q: Can I Wash Sleeping Bags?
A: You can, but you have to do it very carefully. There are different ways to wash an ultralight bag versus a mummy sleeping bag, and so on. The best way to ensure you have a cleaning method for just about every type is to invest in a washer without the central spire. Some sleeping bags, (such as ones with real down, which are the warmest sleeping bags you’ll ever rest in), can get ruined from that spire. Even fluffing it after the fact won’t do much good, so follow this simple method to keep your sleeping bags clean.
- Use paper towels or a slightly damp cotton face cloth to clean exterior areas. Turn the sleeping bag inside out to clean other spots where you may have sweated. If you still feel that there’s a funky smell or it just didn’t come to clean the way you wanted it to, move onto the next step.
- While it’s inside out, use the cold or delicate setting on your HE washer, and put it in for a short cycle. The goal here is to clean the liner and shell, not to completely soak the insulating material if you can avoid it.
- Take a tennis ball (we’re not crazy) and throw it in your dryer. The only other thing that should go in there is your sleeping bag. The tennis ball knocks around repeatedly and fluffs your sleeping bag while it’s drying, effectively keeping it fluffy and preventing the insulation from separating.
Q: What is a Good Weight for Backpacking Sleeping Bag?
A: You generally want to carry under ten pounds, though that isn’t always an option. Depending on where you’re headed, your travel sleeping bag may bulkier and designed for lower temperatures. When you’re dealing with extreme temperature ratings, getting an ultralight sleeping bag becomes more difficult, particularly if you’re in the market for a two-person sleeping bag.
As a rule of thumb, you should know what your backpack can hold, what you can reasonably carry, and how much of that total carry weight is going to be dedicated to your sleeping bag. For single-season campers, you can absolutely find inexpensive, two to five-pound sleeping bags that do the trick just fine, even against mild cold snaps. If you’re a three or four-season camper, you’re stuck with better-insulated options, but at a higher carry weight.
