You’ve got your summit day kit dialed in, your favorite pair of hiking shoes picked out, and you’re just about packed for the ultimate outdoor summer adventure. So when you get to your campsite after a long road trip of grueling hike into the wilderness, don’t get caught unrolling the same musty sleeping bag you used to surf couches back in your college days. These 10 sleeping bags bring the comfort of home to the dirt floors of the high country, and everywhere else, for that matter.


Marmot Always Summer

Best Summer Weight Sleeping Bag: Marmot’s sleeping bag line wins awards with every update, so it’s no surprise that the Always Summer, a 40-degree down bag, once again garnered a lot of praise from testers. Water repellent down, stretch baffles, and insulated zipper guards and draft collar make this the perfect bag for warm summer camping.

Eddie Bauer Airbender +20

Best New Technology: The guides and design team behind Eddie Bauer’s First Ascent line have redefined lightweight with their new Airbender bag. At just over three pounds — including a built-in inflatable air pad — the combination Climashield and DownTek insulated, waterproof bag is the perfect lightweight expedition sleeping solution. It’s also the most expensive on our list, a fine example of getting what you pay for.

Nemo Tango Duo Slim 30

Best Bag For Couple’s Camping: We’ve all tried to zip a pair of conventional mummy bags together for some more “intimate” camping. The result? Uncomfortable sleeping and flaring tempers all night. The Tango Duo sleeping bag from Nemo is the camping equivalent of a full-sized bed. It comes complete with a slip cover to attach any two 20-inch-wide sleeping pads, which fit inside the bag; because it has a backless design, it packs down to the same size and weight of a traditional bag. It’s an ideal solution for those who want to stay active off the trail, too.

Western Mountaineering TerraLite

Best Made-in-America Sleeping Bag: When you start talking to the ultralight climbing and thru hiking crowd about their sleeping arrangements, a handful of brands make the cut. Western Mountaineering’s ExtremeLite series of sleeping bags are without a doubt part of that elite set. Featuring 850+ fill power down, microlight 12- and 15-denier nylon shell fabric and a dual zipper (plus foot box zipper), the TerraLite is a perfect bag for campers who want a superb bag weighing less than two pounds. Did we mention all their bags are handmade in the USA?

Kifaru Slick Bag

Best Sleeping Bag For Hunters: Colorado-based Kifaru got their start in 1978, and the Slick Bag harnesses their decades of hunting and tactical innovation. Featuring RhinoSkin shell and lining that the company says will stand up to boots-in-bag use, continuous Climashield insulation along the whole body, expanded shoulder space and extra-wide foot boxes, the Slick Bag is an excellent extreme conditions bag.

3 Sleeping Bag Factors to Look For


You’ll find all kinds of features and specifications in the search for your next bag, but the following three variables are what matter. Keep an eye out for them.

Temperature Rating: This one’s obvious. Choose your bag based on the coldest temperature you plan to be confronted with. The ratings are standardized based on the “EN Standard”.
Insulation Type: Down, synthetic, and now DriDown. Down is lightweight, breathable and compresses well — but pricey; synthetic is better for cold or wet conditions — and typically cheaper; DriDown is new and offers the best of both.
Weight vs Space: Choose based on what matters more to you or the conditions you plan to backpack in. You don’t want to carry a heavy load, but last we checked, a good night’s rest is critical on the trail.

Big Agnes Zirkel SL 20

Best Sleep System: We spotted the DownTek-treated Zirkel SL at Outdoor Retailer this winter and we’ve been excited about it ever since. Featuring an integrated sleeping pad sleeve along the bottom, the bag ensures you’ll never wake up alongside your padding rather than atop it. Pertex fabric, Insotect Flow Construction (for uniform heat distribution) and water-repellent down round the Zirkel out as a perfect bag for wet environments.

REI Expedition

Best Sleeping Bag For Extreme Weather: REI’s -20 degree Expedition bag is a true four-season bed. A double zipper system allows you stay comfortable in any temperature; unzip the inner zipper to reveal a little extra space and dump heat, or keep both zippers closed when you’re high above the treeline. Water-repellent down and face fabric, as well as an independent hood and collar closure, firmly plant the Expedition as a powerhouse for heat retention. It might be overkill this summer, but if you’re heading anywhere high altitude, you’ll thank us while your partners shiver all night.

Ticla Rambler 15/25

Best Sleeping Bag for Car Camping: Loading up the car with all your best gadgets and extras for a night near your favorite lake or the festival grounds? Throw in the Rambler. It’s reversible, with different temperature ratings for each side, so you’ll be prepared for any weather through summer and fall. It’s also designed to be stuffed in Ticla’s G.O.O.D. system, which means you pack the bag, pad and miscellaneous gear into one camp-ready kit.

The North Face Mercurial 1S

Best Fast and Light Sleeping Bag: Weighing in under two pounds, the Mercurial 1S is perfect for ultralight fastpackers and hammock campers. The semi-rectangular cut has extra room to fit a liner bag ($109+) for extra warmth (it’s rated at 45 degrees alone, so you’ll probably need the liner most of the year). The Primaloft Sport insulation is wicking, so even humid nights or desert camping will be comfortable year-round. As a bonus, both the Mercurial and its liner unzip to lay flat for blanket or comforter use around camp.

Sierra Designs Backcountry Bed 800

Editor’s Pick: A zipperless sleeping bag? It may seem a little strange at first, but the Sierra Designs Backcountry Bed’s unique comforter top is the most versatile and comfortable sleeping bag we’ve used in years. The inner comforter can be tucked in or folded out for different temperatures, and the foot vent, hand pockets, and sleeping pad sleeve make it an effortless favorite. Sierra Design’s 800 fill DriDown is the finishing touch for a three-season bag weighing in at only two and half pounds.

Nothing ruins a backpacking trip like a terrible night’s sleep (or a lack of clean underwear, but if you can’t figure that one out you’re beyond our help). A good sleeping bag is the key to staying warm and dry when you’re crashing under the stars — so you’re at your best crossing that next 8,000 foot mountain pass. Sleeping bag tech has made its way into the space age in the last few years: your 20-year-old bag from summer camp or the Boy Scouts is no longer up to snuff. What separates the new from the old?

New water-resistant breathable materials used in outer shells and linings designed to keep you dry are the norm. Synthetic insulation like PrimaLoft and Quallofil are emerging as competitors for goose down, which is still the standard in warmth-to-weight ratio. There is even a definitive standard for temperature ratings so there’s no more guesswork about whether you’ll be shivering all night. The most important details, though, are a little more personal: fit, weight and price. We’ve put together a list of the best 20°F (or below) bags for three-season camping. We’ll let you be the judge of what works best for you. Keep in mind that the best research you can do is head to your local outdoor store and get in a few bags to figure out your preferences. Hit the snack section first and make a night of it.

REI Igneo

Best All-Around Sleeping Bag: Thanks to its 800-fill down and superlight shell, the Igneo is one of the lighter bags on our list. Sporting a new waterproofing coat developed by Toyota and a performance cut, it does away with some of the frills but none of the comfort. If further warmth is a must, the Magma bag adds additional down to push the comfort rating to 7°F. REI sleeping bags are competitive in terms and price and warmth-to-weight — easily the best all-around for any adventure you can throw at it.

Marmot Cloudbreak

Best New Tech Sleeping Bag: Marmot’s body-mapping technology puts their Thermal R Micro insulation in all the right places to keep you warm without overheating. Their dual-hood closure is also a novel feature: different shaped shock cords around the head and neck keep you comfortable rather than tightening the hood like a noose. Finally, the full-length baffle keeps heat sealed in even when you need to unzip yourself for a little venting.

Sierra Designs Pyro Maniac 15/30

Most Versatile Sleeping Bag: The Pyro Maniac splits the difference between ultra warm and light weight. It’s got an optional down comforter that buttons into the main bag for added warmth down to 15° during spring and fall camping. Without it, the Pyro Maniac is most at home as a summer bag for lightweight camping and trekking. It’s also got the added comfort features of a pillow sleeve in the hood and an ergonomic foot box for extra space.

Kelty Cosmic 20 Degree Down

Best Budget Sleeping Bag: For a more budget-friendly option, Kelty’s Cosmic down bags fit the bill. While they’re plenty warm, the 550 down isn’t as compressible or warm as some of Kelty’s competitors, so they use more of it — not ideal if space and weight are your priorities. However, the roomy fit, ground-level seams and integrated sleeping pad loops ensure a comfortable night. Bottom line: If you’re an ultralight hiker planning a week-long trek, this probably isn’t your bag. If you’re looking for a car camping bag, you’re good to go.

Eddie Bauer First Ascent Karakoram +20°

Most Comfortable Sleeping Bag: Eddie Bauer has a storied history with down. They outfitted the first American ascent of Everest in 1963, and mountaineers and ski guides have had a love affair with EB gear ever since. The Karakoram line of sleeping bags continues this lofty tradition. Using 850-fill down and Pertex shell material, it’s one of the more feature-rich bags on the list. A roomy foot box, interior pocket for essential gear, and full-length draft collar and baffles round out a nearly perfect bag. The only down side? Pertex isn’t incredibly breathable, so it may take a little extra time to loft up after being unpacked, and if moisture penetrates the shell it can severely hamper the performance.

Sierra Designs DriDown Zissou 15 Degree

Editor’s Pick Sleeping Bag: Sierra Designs is the only company to be featured twice on our round-up, and the reason can be summed up in one word: DriDown. Wet and warmth normally don’t go together with down, but a proprietary chemical treatment on Sierra Designs’ 700-fill down allows it to keep its loft even after absorbing 20-30% of its weight in water. It’s not the most roomy and a little heavy because of the 700 fill, but if you’re worried about getting wet and willing to pay a little premium, the Zissou is your best bet to stay warm and happy.

Feathered Friends Hummingbird Nano 20

Best Ultralight Sleeping Bag: It may be the most expensive bag on the list, but ounce for ounce, the Hummingbird is one of the warmest around. At 1 lb 10 oz, this bag can be compressed down to the size of a Nalgene bottle. The trade off? At times it feels like it might compress sleepers. If you’ve got wide shoulders or hips, you might get a little claustrophobic. It’s not the most waterprrof, or the roomiest, but this ultralight bag is just begging to be taken on a long trek down the Pacific Crest or Continental Divide Trail.

Sea To Summit TkII

Best Recreational Travel Sleeping Bag: Sea to Summit was founded in in the 1990s by an enterprising group of Australian climbers who trekked from the beaches of the Bay of Bengal to the peak of Everest. On foot. Without supplemental oxygen. Today their sleeping bags incorporate all the lessons learned from more than two decades of climbing in the world’s harshest climates. The TkII is no slouch when it comes to repelling water, but what really sets it apart is the attention paid to the fill pattern: none of the 650-fill down is wasted in unnecessary baffles or quilting. It’s no show stopper, but with Sea to Summit’s solid track record, you could do worse.

L.L. Bean Katahdin 20

Best Updated Sleeping Bag: L.L. Bean recently updated the insulation in the Katahdin to PrimaLoft Synergy, which is the only insulation on the market that is inherently water repellent. A Durable Water Repellent (DWR) treatment is woven into the insulation and lining to ensure that you stay dry no matter the conditions. The cut was also updated to include a little more room at the shoulders and hips so you don’t feel constricted. Heavy duty rip-stop shell material resists abrasion while maintaining a degree of stretchiness. At just over 3 pounds it’s not the lightest or most compressible bag, but it is one of the most comfortable.
