The mostly rectangular shape of the Big Agnes Lulu Women's 15-Degree Synthetic Sleeping Bag gives you room to sleep in more positi...ons than just on your back mummy-style. The Lulu's not a superlight expedition bag, but it does pack a punch with synthetic Integrity insulation that's warm to 15 degrees, as well as an Insotect Tubic vertical baffle construction that provides more loft, trapping more air and therefore supplying more warmth. It also stays warm when it gets soggy, something down insulation doesn't do. Since it's not made for super-long trips, the Lulu sacrificed a little bit of weight to provide more room, with a rectangular shape and extra space in the hip and feet areas, which provides better warmth as well as a more comfortable fit. It saves even more poundage by eliminating traditional ground insulation, instead keeping you warm by requiring a sleeping pad that slides into the integrated pad pocket, insulating you from the ground more effectively than traditional constructions. It keeps cold air at bay with a no-draft collar, zipper, and wedge to keep your mom, your sister, or your friend warm and on the pad all night long. Given its pillow pocket and soft nylon taffeta lining, they might just end up staying in it all day, too. Read More

As far as sleeping bags go, 3. 25 pounds is really light. When you're talking about a bag that will keep you warm in the dead of w...inter, however, 3. 25 pounds is ridiculous. On top of the warmth, the Storm King 0-degree Sleeping Bag has a roomy rectangular design and can even be zipped together with another rectangular bag. The main reason for this ultra-light weight is the fact that Big Agnes eliminated the unnecessary insulation from the bottom of the bag. When you're sleeping on top of insulation, it doesn't keep you warm because it has no loft and therefore no air istrapped inside to keep you warm. Instead, Big Agnes put a Sleeping Pad Pocket in its place, so you have the trapped air in the sleeping pad keeping you warm and at the same time you can't roll off the sleeping pad. Read More

Twelve years ago Big Agnes dove headfirst into the fray of designing gear for the outdoor world. It introduced the unique Big Agne...s System (sleeping bags with a pad sleeve on the bottom instead of insulation) and defined a new level of comfort for hitting the sack at night. Now, for the first time since the brand was born, Big Agnes has revived the traditional mummy bag design and redesigned its insulation and technology from top to bottom. The result is Bellyache Mountain SL17-Degree Sleeping Bag, a technical, three-season sleeping bag that conquers wet nights in the spring and cold mornings in the fall. Perhaps the most notable feature of the Bellyache is the Downtek Insulation. This water-repellent down retains loft, breathability, and insulation value even if the down itself gets wet from rain or moisture. This gives you a serious advantage over traditional down insulation that clumps and lies flat at the first sign of moisture. Even with high-end insulation, a sleeping bag is only as good as the baffles that hold its insulation and the Bellyache uses Flow Construction, one of the most innovative baffle constructions in the industry. Insotect Flow uses a series of vertical baffles with internal gates that eliminate vertical and lateral clumping by constantly evening the distribution of insulation from head-to-toe, thus eliminating cold spots. Along with draft-stopping features like a seal around the neck opening, a wedge between the sleeping bag and sleeping pad connection, and a no-draft tube along the zipper, this sleeping bag offers reliable, regular warmth throughout the night. Amazingly, for all its cold-and-wet-weather advantages, this sleeping bag maintains a weight well under three pounds. Along with your insulating layer and a wool hat, this versatile 17-degree bag should be an essential part of your kit whether you're pitching a tarp in the Pacific Northwest or pitching a single-wall in the Carolinas.

Moving fast and light in the backcountry doesn't mean you can ignore the weather. Despite its unbelievably low weight, the Mountai...n Hardwear Mtn Speed Down Sleeping Bag is rated at a versatile 32 degrees, which is plenty warm for spring, summer, and fall camping in most areas of the US. The reason for the low temperature rating and low weight is super-high-quality 850 fill-power goose down, which is treated with Mountain Hardwear's innovative Q. Shield water-repellant. Q. Shield is used on the down fibers to maintain the down's insulating properties if the down gets wet, so the days of using synthetic bags in wet areas are over. Read More

In the past, drafty cabins and frosty tents may have kept you from a good winter night's sleep, but now that you have the Big Agne...s Farwell 0-Degree Synthetic Sleeping Bag to burrow inside, you snore the nights away (your travel partners would prefer that you shivered). Stuffed full of Integrity synthetic insulation like a turkey's stuffed full of, well, stuffing, the Farwell will keep you warm all the way down to zero degrees, making it a top option for icy winter hut trips and camping expeditions where going superlight isn't necessary. Synthetic doesn't pack quite as well as down, but it compensates by retaining its warmth even if it gets wet and staying well-lofted, so you don't have to worry about condensation turning your bag into a popsicle. To reduce weight as much as possible, the Farwell forgoes insulation on the bottom of the bag, opting instead for an integrated sleeve that uses a sleeping pad as insulation, letting the bag pack down smaller than it otherwise would while the pad keeps you warmer than traditional insulation, which would only compress under your weight. The Farwell also has winter-defeating features like a no-draft collar, zipper, and wedge, a pillow pocket, and comfortable nylon taffeta lining that will keep you deeply asleep, even if your tentmates start bashing you with shoes and headlamps to stop the racket.

Despite warmer weather during the day, mountains and deserts will cool off at night, leaving you shivering if you're not prepared.... The Big Agnes Gunn Creek 30 Degree Synthetic Sleeping Bag surrounds you with heat-trapping Integrity synthetic insulation (kept in place by the vertical baffles) so you can snooze comfortably through the night, and has a roomy rectangular shape that lets you move around a little bit, too. The innovative Big Agnes Insoctect Tubic system optimizes the efficiency of the eco-friendly Integrity insulation by structuring it to create vertical thermal channels running the length of the bag that trap air to add comfort and warmth. To reduce weight as much as possible, the Gunn Creek forgoes insulation on the bottom of the bag, opting instead for an integrated sleeve that uses a sleeping pad as insulation, letting the bag pack down smaller than it otherwise would while the pad keeps you warmer than traditional insulation, which would only compress under your weight. A pillow pocket is also included so you don't wake up with your head mashed into the cold, hard ground. The no-draft collar, wedge, and zipper keep cold air out and insulate you against the ground, and you can even mate left- and right-zip bags together, because, after all, the best way to stay warm is to sleep with a partner.

Marmot celebrates its heritage and its 40th anniversary with the Meteor Penguin Sleeping Bag. So maybe Marmot got a little sentime...ntal in creating this 700-fill goose-down bag, but with it's history of rugged and lightweight gear built to perform in a wide variety of conditions, a little nostalgia works in your favor. Ideal for hiking the high passes of the Sierra Nevadas or scrambling in the Alps, the Meteor Penguin features lightweight but tough 30-denier ripstop nylon shell fabric and Down Defender for added protection in wet conditions. Rated to 15 degrees Fahrenheit, this bag will keep you cozy on the coolest of spring and fall nights, and expertly designed features like a down-filled oversized draft tube, ground-level zipper, hood muff, and Nautilus 3D baffle hood further prevent heat-loss and draft. Designed, filled, and finished in Rohnert Park, California, the Meteor Penguin offers features of convenience and comfort, like a trapezoidal footbox that is wider in the toe area, just like your foot. A drawcord locker keeps the cords from dangling in your face while you try to drift off to dreamland, and hang loops allow for easy airing out after things get damp. Locking zippers with two-way zipper slides add to the convenience of use. You can't beat the Meteor Penguin's looks, either, as cobalt blue and sunset orange contrast each other in throw-back homage to Marmot's humble beginnings. Read More

Lighting up the spring, fall, and mild winter skies, it's the Marmot Meteor 15-Degree Down Sleeping Bag. This lightweight nylon ri...pstop bag is loaded up with 700-fill goose down to keep you warm on chilly October nights, brisk April mornings, and steamy January hut trips.

With a snug Nautilus six-baffle hood, insulated draft tube, and snug collar, you'll be able to seal yourself up tight against the cold, no matter the season.

Spring, fall, and mild winter camping can reward you with colorful vistas that you didn't know existed, but without the Big Agnes ...Encampment 15-Degree Synthetic Sleeping Bag to keep you warm at night, you might be too busy shivering and cursing the cold to pay them any attention. Luckily, the Encampment is packed full of 97% recycled Integrity synthetic insulation to keep you warm, and has an integrated pad sleeve and insulating wedge so the cold from the ground doesn't seep into your bag and turn you into a snoozy popsicle. To reduce the size and weight of the bag, Big Agnes eliminated insulation on the bottom (it only packs down under your weight anyway), instead requiring a compatible sleeping pad to insulate you from the ground. Bonus: you won't roll off onto the ground anymore. The Encampment is designed with Insotect Tubic baffle construction, which is a tongue-tying way of saying that the high-loft baffles run vertically, conforming to your body for maximum heat retention and comfort, while keeping the insulation where it belongs. You don't have to worry about your pillow running away at night, as Big Agnes gave this bag a built-in pillow pocket, nor do you have to stress drafts, since there is a no-draft collar and zipper to keep sneaky cold air where it belongs. If you have two left-zip and right-zip Encampments, you can even mate them together to create a double-wide bag, so you don't have to be sad about sleeping alone. Read More

Its comfort mummy cut provides a slightly larger shape than standard mummy bags for extra relaxation without adding weight. Mountain Hardwear made the Ratio's shell out of dobby for durability, and the taffeta lining is smooth to the touch for extra comfort. The down-filled face gasket at the hood and the insulated draft tube across the zipper keep chilly drafts out of the bag throughout the night. The hood features single-handed drawcords that cinch snugly with a simple pull. Read More

There's no need to pack an expedition-style sleeping back for a quick summer overnight or backyard camping trip, so save weight an...d space by grabbing the Big Agnes Cross Mountain 45-Degree Synthetic Sleeping Bag instead. At under two pounds it won't slow you down or fill up your pack, and it'll be comfortable on mild summer nights, unlike a heavy-duty winter bag that'll just make you sweat. To reduce weight as much as possible, the Cross Mountain forgoes insulation on the bottom of the bag, opting instead for an integrated sleeve that uses a sleeping pad as insulation, letting the bag pack down smaller than it otherwise would while the pad keeps you warmer than traditional insulation, which would only compress under your weight. The mostly-recycled Integrity synthetic insulation stays warm even if it gets damp, and if you've got two Cross Mountain bags with left and right zippers, you can even mate them together to make a double bag and cuddle up with a lucky someone.

Brainiac scientists tell us that the sun's made primarily of plasma, so it stands to reason that Marmot would make the Plasma 15 D...own Sleeping Bag out of the same hot-hot-HOT material; unfortunately, Marmot's bag designers couldn't quite figure out how to sew plasma and magnetic fields into a functional sleeping bag, so they opted for 875-fill goose down wrapped in bulletproof Pertex Quantum fabric for the ultimate combination of warmth and lightness. The Plasma's designed to be comfortable in chilly temperatures: as low as 15 degrees, with a comfort rating of 29 degrees. It weighs less than a galaxy's worth of anti-matter--just under two pounds--and packs down smaller than the beginning of the Big Bang, so you won't notice it in your pack any more than you'd notice a few extra protons. This combination of weight and warmth is made possible by the Insotect Flow vertical baffles, which direct heat downwards to the wrap-around footbox, minimizing the amount of down required to keep you toasty. Down also loses most of its insulating value when it gets wet, so Marmot designed the Plasma an inner and outer DWR coating, and treated the insulation with Down Defender, which helps it maintain loft it things do get a little soggy. There are also small touches that make a big difference, like a cold-air defeating insulated draft tube, insulated collar, and face muff to seal your bag up tight against the chill; if you get cold, it's probably because you've taken the Plasma somewhere it doesn't quite belong, like the moon.

Slavonia might seem like a strange name for a sleeping bag (historical regions of eastern Croatia for $500, anyone?) but hey, anci...ent Slavs and Ottomans probably slept outside a lot, and odds are good they didn't have anything as warm and comfortable as the Big Agnes Slavonia Women's 30-Degree Synthetic Sleeping Bag. Packed with synthetic Integrity insulation, the Slavonia's a perfect choice for summer camping and backpacking trips where you need moderate insulation without having to worry about going superlight. It does trim weight, however, by eliminating traditional ground insulation, instead using an integrated sleeve to hold a required sleeping pad that better insulates you from the ground and lets the Slavonia pack down small. Designed with a rectangular shape to give you more room to spread out, the Slavonia uses Insotect Tubic baffle construction, which ensures the fill retains its high loft and conforms to your body for superior comfort and warmth. It also features a pillow pocket so you don't wake up lying on the hard, cold ground with your face smashed into a rock, and has a zippered stash pocket at the shoulder so you can keep whatever you need handy all night long. A no-draft collar and no-draft zipper keep--wait for it--drafts at bay, and compatible left and right zippers can be mated together to form a double-wide sleeping bag so you and your favorite camping companion can cuddle up for warmth.
