Sleeping Bags
Archive
In the past month, I’ve camped at the Wildflower Triathlons, and at the Deuces Wild Triathlon festival. Both times it felt like my sleeping bag wasn’t as warm as it used to be. Do sleeping bags expire?

I'm looking for a sleeping bag for extreme cold temperatures. I'm talking Arctic. What's my best option?
First things first: your pack will be heavier. You’ll be packing more food, fuel, and layers. As for shelter, if you’re not expecting high winds or heavy snowfall, you probably don’t need to upgrade to a four-season tent; a sturdy (read: not ultralight or mostly mesh) three-season model should see you through.

What's the best lightweight gear for a weekend backpacking trip?
I need to update my gear closet for a weekend backpacking trip in Arizona. I can't afford to spend much, but my husband and I are aiming to hike upward of 15 miles each day and I don't want to be weighed down. Any suggestions?
My wife and I recently went car camping. It was her first trip. She enjoyed it a lot, but the mummy-style sleeping bag I borrowed for her wasn’t comfortable. Too restrictive. What do you suggest we try?
I'm going hiking in Bolivia, and I'm thinking about using an emergency blanket instead of a sleeping bag. Thoughts? Any recommendations on a liner or material?

I will be thru-hiking the John Muir Trail this summer and would like your opinion on sleeping bag. I currently own a synthetic, zero-degree bag that is an unappreciated 4 plus pounds. I know this is too heavy (as I thru-hiked the Colorado Trail with it). My real question: can I get away with a 30-degree down bag, or should I look more at a 15- to 20-degree bag? I tend to be a somewhat cold sleeper. I am 6'2", 190 pounds. I know the temperature ratings are guestimates at best, but your input would help. DaveDolores, CO
Why It RulesAs a custom shop, Feathered Friends tailors each of its bags exactly to your specifications, meaning you get your choice of fabrics, color, and even zipper location. I picked the Pertex Quantum interior for breathability and the Epic exterior for water resistance—the combo tipped the scales at just…
Conjuring a packable, synthetic cold-weather bag is a tough trick, but EMS pulls it off by stuffing the Velocity 5 with highly compressible PrimaLoft Sport insulation, wrapping it in a superlight Pertex Quantum shell, and pairing it with a compression stuffsack. The bag is a smart, affordable choice for…
BARGAIN SYNTHETIC Confession: I was nervous diving into the 20-degree Klickitat when the forecast called for below-freezing temps. Its uninspiring loft just doesn’t say “sweet dreams.” But I stayed plenty warm, making this inexpensive sack one of the year’s best deals. The trick? A new synthetic insulation, called Climashield XP,…
It’s slightly dubious that a bag that packs down to the size of a tennis shoe can keep you warm, but even on a 38-degree night, you’ll be snug. Credit the 650-fill down insulation and an additional interior foot pouch that can be pulled over your toes. 40°F, 1.6…
Why It’s CoolThe gaudy gray-and-orange patterns of the bag’s nylon shell start to look pretty attractive when you remind yourself how little you forked over here—this is the biggest bang for the buck on the market. Fashioned with a taffeta lining and stuffed with DuPont Thermalite insulation, the 30-degree Super…
Tent walls condensing like a steam room? Roll over and go back to sleep in the Sierra Designs Trade Wind. The down bag’s waterproof shell is impervious to weather that will wilt the feathers of lesser bags like, well, a cold shower. But that’s not all. Premium down fill,…
BETTER THAN YOUR BED Letting your car do the carrying for you? Sleep like royalty in the Luxor. It has 650-fill down on top and synthetic material underneath, where feathers get squashed. Fittingly, it has a laundry list of creature comforts, such as a flannel-like liner, handy pillow sleeve, and…
Synthetic bags tend to have worse weight-to-warmth ratios than down. But the 25-degree Kira comes much closer than most, thanks in large part to the bag’s unusual internal-collar design, which snaps around the neck but still leaves plenty of space for claustrophobes. 25°F, 4.1 lbs; mammutusa.com…
Why It’s CoolAgnes replaces the hood with a rectangular pocket that you stuff with your clothes (tip: stick to the clean stuff) to make a pillow. Given that you won’t be braving arctic nights in this summer-weight bag, a hood is less critical—and the pillow feature is pretty plush. »…
The Light Year looks like many other 650-fill down bags. It packs small and is plenty lofty. Unlike others, it zips open at the feet, letting you micromanage temperature. And on cold mornings, the foot opening lets you walk around without getting out of the bag. Even “I never…
ULTRALIGHT SUMMER BAG You tend to pay more to carry less in the rarefied class of one-pound, down summer sacks. That’s why the barely-over-a-pound Flash is such a surprise: For packability, weight, and warmth it rivals bags that cost much more. And there’s nothing cheap about its silky shell and…
With few bells and whistles, this lightweight bag, made with PrimaLoft MXL insulation, compresses to the size of a 12-pack—making it ideal for the fast-moving backpacker. Just don’t push it: There’s no collar, and a few testers got chilly on nights colder than 35 degrees. 25°, 3.3 lbs;…
Why It’s CoolCuddling up to the two-pound-two-ounce Sub Kilo definitely took the edge off a few damp, chilly nights in the Green Mountains of Vermont. Two curvy lines stitched down the length of the bag to prevent the 700-fill goose down from clumping worked as billed: No cold spots arose…
You: A girl who’s not afraid to admit you’d like camping better if it came with satin sheets. Your bag: The Sub Kilo +15, with its buttery polyester lining. Stuffed with 750-fill down—with extra insulation in the footbox and hood—this is the warmest bag tested, but still a cinch…
ALL BUSINESS Sporting a mini (12-inch) zipper and an aggressively athletic fit (looks like it’s designed to fit a lollipop), the Epic is the leanest, meanest bag here. You can even use it sans tent: Its waterproof, taped shell was unfazed by damp nights. The catch? It’s probably too constrictive…
It’s what’s on the inside that matters most, and because the Boreal 20 is stuffed with some of the loftiest, most compressible synthetic insulation around, it’s remarkably warm and cushy for its weight. Bonus: The ergonomically tailored foot area and hood are designed specifically for women’s bodies. 20°, 2.7…
Why It’s CoolHere’s a sound argument for topping off your gear closet with an affordable, ultralight bag for warm-weather overnights. The Phantom takes up less room in a backpack than some fleece jackets and weighs less than a bag of gorp. » The zip is three-quarter-length (to trim weight) and…
It’s like a closeout deal without the closeout. This Thermolite Micro–filled sack has cozy touches not typically found on a summer bag, like extra chest insulation, a fleece liner at the feet, and a draft tube and full hood. And it still packs so small we stuffed it in…
LUXURIOUS LIGHTWEIGHT This 2007 Gear of the Year summer bag is super-soft and impressively warm for the low weight. Plus it lets you chill without being chilly: It unzips to the hips on both sides, freeing your arms for reading or cooking while keeping the rest of you snug.
For such a light and warm bag, the 800-fill Peggy is packed with such thoughtful features as a built-in pillowcase. Like all of Big Agnes’s bags, there’s no insulation on the underside, but it’s compatible with any 20-inch-wide sleeping pad. 15°, 2.5 lbs; bigagnes.com…
Why It’s CoolI know campers who bed down with a Nalgene full of hot water for extra warmth; my wife prefers our 20-pound pug. Seeing the two of them in the Van Winkle—with its stretchy bands on the baffles for an extra-snug fit—reminded me of a snake that had swallowed…
For the no-frills gal who thumbs her nose at floral details and feminine colors, Marmot’s ultralight synthetic bag delivers women’s features in gender-neutral style. Primaloft Sport insulation crushes almost as well as down, and there’s extra fill at the feet, hip, and shoulder. 25ºF, 1.9 lbs; www.marmot.com Bonus:…
SUMMER SLEEPER With a hood and pillow pocket, an external earplug pocket, full zip, and straps for holding your mattress in place, the Kaya is full-featured for such a compact bag. Filled with Polarguard Delta insulation, it sports a trimmer fit than the other bags we tested, which makes it…
If we had a Most Comfy award, this recycled-synthetic Climashield bag would win. Credit the recycled Cocona liner—which wicks moisture and feels more like sheets than slick nylon—and the cozily lined foot area. The trade-offs: It’s not as compressible as other synthetics, and it’s a tad heavy. 5°, 3.4…
Why It’s CoolWhen considering an envelope rated to 40 degrees or higher, make sure it’s light. The Butterfly weighs in at a pound and change. It shaves ounces by using a quarter-length zip, 700-fill down, and moisture-repelling Pertex Quantum fabric for the shell and liner. » An interior storage pocket…
LOVABLE ODDBALLWith a slide-in pad replacing ground-side stuffing, the Crystal is one strange bird. But it’s also hosted some of the deepest slumbers of my life. Coziness arrives courtesy of an insulation-layering scheme called Dualmax, which intersperses slabs of Primaloft with batts of 650-fill down. As I flipped in sleep…
BEST FOR COLD SLEEPERS If your camping plans involve high altitude or shoulder seasons, the toasty full-zip Down Lady should be the first thing you pack. Its 650-fill down is wrapped in a water-repellent ripstop nylon shell. Other features include a fat collar and draft tube, and a hood…
1. Thanks to its top-of-the-line 800-fill down, light fabrics, half-length zipper, and trim cut, the Adrenaline 20 packs down to the size of a loaf of bread. Even more impressive, at less than two pounds, the Adrenaline is about a half-pound lighter than the average 20-degree down bag. Add…
Why It’s CoolThis one-pound-three-ounce bag has no hardware—no zip, no Velcro—just a single cinch clasp on the hood’s drawcord. » The Beeline is rated to 30 degrees, thanks in large part to the 900-fill goose down’s impressive loft. » Shaving additional grams is the Pertex Quantum fabric used in the…
SLEEK SLEEPERMountain Hardwear welded bag-length sheets of its new Thermic CF insulation inside a nylon sandwich to make a uniformly warm 15-degree sack that’s compressible and affordable. On a late-season attempt on the North Cascades’ Liberty Bell Mountain, I clunked into camp with frozen toes, easily shoved my size-12 feet…
BEST ULTRALIGHT The Kilo’s polyester taffeta lining is decadently soft, and because it has extra amounts of lofty 750-fill down in the feet and shoulders, it delivers on its temp rating. It’s so small and light one tester stashed it in her purse. 35°F, 1.3 lbs; rei.com Bonus:…
Nothing is worse than being rudely awakened by rain when sleeping out sans tent, which is why testers had high praise for the 15-degree Shield. For starters, the 800-fill down is wrapped in a proprietary waterproof-breathable fabric that’s nearly as tough as Mammut’s burliest shells. And if it starts…
Why It’s CoolThe loft of the 900-fill down in the Helium EQ is simply amazing. This is one plush, comfortable bag—all the way down to the mid-teens. » It tips the scales at two pounds three ounces, largely because of a Pertex Quantum nylon shell that is waterproof, windproof, and…
SOLID PERFORMERThis one doesn’t exactly scream “sexy beast,” but SD has always prioritized the basics—manifest here in details such as anti-snag seams. The best thing about the three-pound-four-ounce Arrow Rock is that “toasty” (it’s rated to 15 degrees) isn’t spinspeak for “cramped.” On a nippy late-summer outing in North Cascades…
1. It’s partly recycled, yes. But the Verde won this year’s award because of how it performed in the field. It’s all about the fill: The Verde’s insulation (Climashield Green) is “continuous filament,” meaning it won’t clump or shift—and create cold spots—as old-school synthetics do. 2. The insulation…
Campers who feel claustrophobic in tight mummy bags will love the Cochise’s stretchy construction. The baffles of this 15-degree, synthetic-fill bag are sewn with elastic fabric, so you can squirm around without resistance—and even sit cross-legged to cook or read. The other upside to this elasticity: When you stop…
Why It’s CoolThis is the first year that Valandré bags have been distributed in the United States, but it won’t be the last, despite the shocking price tag. Why? Old World craftsmanship. Each bag is hand-sewn in the Pyrenees from 48 panels of fabric. The slim chambers are amply filled…
1. Last year, Mountain Hardwear wowed the sleeping-bag world (OK, us gearheads) with its welded-insulation Lamina series. Even non-sleeping-bag geeks will appreciate this upgrade: The UltraLamina 32 is lighter (2.1 pounds) and compresses down to almost two-thirds the size of its predecessor. 2. Hardwear chopped up its synthetic…
PLENTY OF ELBOW ROOM With elastic in each baffle, this bag expands as you toss, turn, and even sit up cross-legged to cook or play cards. When you finally stop thrashing, the bag’s elastic keeps the thick sheets of MontBell’s house-brand synthetic insulation close to your body, so you won’t…
Need a three-season and a summer-weight bag but can’t afford both? Sidestep the decision with the Chasseral. If conditions are too warm, simply zip off the topsheet, which folds into its own stash pocket, creating a ready-made camping-size pillow. And although the Chasseral is the roomiest bag here, it…
REI changed everything but the name on this sack: Designers kicked up the goose down to 750-fill, changed the shell, and added a lighter, softer liner. The updates shave seven ounces off last year’s version. It kept us warm on late-fall nights in the Grand Canyon, but the tradeoff…
THREE-SEASON ULTRALIGHT Go hard all day and sleep like the dead all night? We liked this bag for both pursuits. It’s light and compressible, thanks to a three-quarter-length zipper, a tapered design, and lofty 750-fill down. The narrow, efficient cut makes it one of the warmest two-pound bags we’ve seen,…
ULTRALIGHT AND COMPRESSIBLE Testers liked Big Agnes’s almost entirely recycled synthetic sack (the Skinny Fish; $180) just fine but were blown away by the down-filled Zirkel’s warmth-to-packability ratio. Like all the company’s bags, the Zirkel integrates the pad right into the bag via a sleeve on the underside, which, in…
EMS’s 20-degree Boreal is the first sack to use a new synthetic insulation from PrimaLoft called Infinity, which EMS claims is “18 percent warmer and 25 percent more compressible” than comparable fill. Although it was impossible to test that boast, the Boreal squashes down to the size of a…
The Summerlite vanishes into a stuffsack too puny to accommodate a few hoagies I’ve eaten. Yet it’s not claustrophobic like some ultralights. Designers achieved the feat by stuffing a gossamer 20-denier nylon shell with 850-fill down and paring back everything else—except warmth. It proved itself a choice summer-plus bag…
DATE NIGHT, UPGRADED The problem: You and your significant other share a love for camping, but your zipped-together sleeping bags and mismatched pad combo are causing a divide. The solution: The King Solomon. When its internal pad sleeves are stuffed with two 20-inch-wide mats, the King’s system works beautifully—there’s no…
A TINY SUMMERWEIGHT BAG The North Face claims that its revamped line of Flight Series bags are the first synthetic sacks to rival equivalently rated down bags in weight and compressibility. We were skeptical, but this 40-degree comes pretty darn close. The secret? It’s stuffed with Climashield’s newest stuff,…
As with previous Kazoos, this 15-degree bag is still stuffed primarily with 600-fill down and bedecked with smart features—glow-in-the-dark zipper pulls, easy-to-adjust hood, etc. Even more impressive, this Kazoo’s shell and insulation are made with 100 percent recycled materials. Plus, it’s a hybrid. There are compression-resistant, synthetic insulation pads…
This fabric accordion expands at the knees, which gave me—a sleeper with restless-legs syndrome—a welcome night of unrestricted tossing and turning. The elastic keeps the Exceloft synthetic insulation close to the body for efficient warmth, though some cold sleepers found the rating a tad optimistic. 32°F, 2.7 lbs; www.montbell.com…
WARM IN ANY WEATHER OK, sometimes sleeping outside just plain sucks—like when it’s cold and wet and you’re without a tent. Fortunately, the Cirque is made for just such nights. On a soggy ski-touring trip in Mount Baker–Snoqualmie National Forest, testers spent two nights en plein air in the 800-fill-down…
BUILT TO LAST The Woodpecker, from Swiss company Exped, is meticulously crafted—just what you’d expect from a nation of legendary watchmakers. (Of course, its heavy-duty zipper is the only moving part.) A well-placed, down-filled chin guard keeps your face from brushing against frosty zippers. Glow-in-the-dark zipper pulls prevent late-night fumbling.
This is the only synthetic-insulated bag we’ve found that matches the loft, weight, and compressibility of a comparably rated down sack. The key is Mountain Hardwear’s proprietary Thermic Micro insulation, which testers found both more compressible and loftier than other synthetics. Plus, the baffles are welded rather than sewn,…
Ounce-counter special: The retooled Hightail has trapezoidal baffles to bolster insulation, a tough new shell, and a cut that’s less stingy at the shoulders than other featherweights. The 900-fill down compresses so well that even the bag’s modest stuffsack is too roomy. Only our coldest sleeper felt slightly chilled…
THRASHERS WELCOME If traditional mummy bags make you feel straitjacketed, you’ll get relief with this stretchy bag. MontBell sews this sack with elasticized thread and extra shell material, so you can bend your knees, sit comfortably with your legs crossed, and generally toss and turn uninhibitedly all night long. And…
VERSATILE THREE-SEASON SACK The EcoPro costs a bit more than Marmot’s other synthetic 15-degree-rated models (like the Trestles 15, $90). But this bag has good karma. Its insulation and shell are spun almost entirely out of recycled plastic bottles. In fact, the only unrecycled things on this roomy bag are…
Not that you’d need it, with SIERRA DESIGNS’ BTU -5 SLEEPING BAG—an 800-fill down heat factory with one of the best heat-sealing hoods we’ve ever tested and a waterproof-breathable fabric.
Behold the Gear of the Year: A 16-ounce, 900-fill-down wonder that’s destined to be the new sleep standard for fastpackers and anyone else who appreciates gossamer weight in a three-season bag. Marmot’s ultrastuffable Atom practically vanishes into your pack. 1. How feathery is the Atom, with its über-premium down and…
Thanks to welded seams and a protected zipper that can withstand a downpour, the Spirit SL is a standout in the growing category of waterproof-breathable down bags. The 800-fill down squashes small in the pack, and the cut is pleasantly roomy, especially in the footbox, which lets the dogs…
VERSATILE THREE-SEASON SACK Now in its umpteenth iteration, the 2007 Cat’s Meow is like its predecessors in one respect only: It’s still one of the most versatile, durable three-season synthetic bags available. The roomy sack is stuffed with lofty, long-lasting Polarguard Delta and wrapped with a tough skin of water-resistant…
EXPEDITION-READY Kelty developed the new Foraker line in conjunction with Alaska Mountain Guides, an adventure outfitter whose guides spend hundreds of days in the field. You can tell: This 750-fill sack is the toughest, most packable sleeping bag Kelty has ever made. It’s cut from three different fabrics. A water-resistant,…
Aigle Shems – Midweight Jackets: Reviews With a soft fleece interior and warm, durable merino wool/nylon exterior, this jacket combines our favorite fabrics in one versatile top. 1.9 lbs; aigleusa.com Patagonia Pau – Footwear: Reviews (Terry Heffernan) The coolest mocs we’ve ever laid eyes…
If you’ve lusted after a high-end, ultralight three-season sack but balked at the price, stop hemming and hawing and buy the Arroyo. It weighs just a zipper fob over a pound and a half, thanks to 800-fill down, and delivers conservative warmth with a comfortable, full-zip design. A nautilus-type…
A LUXE BAG FOR BIG DUDES Norway-based Ajungilak (now owned by Mammut) started making sleeping bags nearly 120 years ago, and the accumulated experience shows in this deluxe, full-featured sack. For starters, the Altitude is made with top-shelf materials, like 780-fill down and a burly, highly water-resistant nylon shell. Plus…
The 15-degree EcoPro is made with a new 80 percent recycled synthetic insulation and 100 percent recycled polyester shell fabric. But it compresses and insulates as well as comparable synthetics and comes with a microfleece-lined collar and a stash pocket. 15°F, 3 lbs; marmot.com…
I am planning to climb Kilimanjaro in December this year. What will be the best sleeping bag and boots tor this trip? –Florin Guelph, Ontario
My son is a Boy Scout and had a very nice and somewhat expensive cold-weather sleeping bag from The North Face. He recently discovered a small tear in the nylon fabric. I am looking for advice about how to patch it. Can you give some advice to a Loyal Scout Mom?
I already own the Mountain Hardware Woman's Sub Zero SL Hooded Jacket and understand that this is not warm enough for Denali. Can I pair this with a lighter 800 fill down sweater to get the warmth that I need? Or must I buy another pricey parka? And on the boot front, my feet get cold. I would like a boot that will get me up Denali, toes intact, but that I can also wear on other climbs in the Lower 48 (and maybe someday in the Himalaya). Is this asking too much? I had a pair of Spantiks but their size made me feel clumsy...—AbiSan Francisco, CA
Are there any good sleeping bags for two people that can be brought on backpacking trips?—Jen MooreOrangevale, California
