It’s rated for 20-degrees Fahrenheit, so it’s still warm without being bulky or too heavy to carry.

We live in Alaska and are able to use them for Spring, summer and fall camping. We love the hood feature and are warm from our head to our toes.” Pros Super lightweight and packable 850+ fill goose down Abrasion-resistant Temperature rating of 20°F Cons Expensive Shop Now Kelty, Cosmic Ultra 800 DriDown Sleeping Bag: 20°F — $200.00 Similarly, this Kelty version offers a premium quality at more than half the price of the Marmot model. This sleeping bag is filled with 800-fill duck down that’s also hydrophobic and fast-drying. It’s shaped similarly, complete with trapezoidal baffles (the horizontal stripes that keep the down in place) to retain body heat. Just note, the regular size is fitted for people 5’8″ or below, so if you’re taller, size up.

I would definitely purchase this again.” Pros 800 fill Temperature rating of 20°F Two locking zippers, including one at the bottom of the sleeping bag Zippered internal stash pocket Cons Regular size only fits people 5’8″ and under Shop Now Sea To Summit, Ascent Down Mummy Sleeping Bag 25°F — $349.00 Sea To Summit knows there’s a lot more that goes into a good sleeping bag than just fill power. The brand’s design team takes everything into consideration, from roominess and shape to the difference in men’s and women’s sleeping styles. The Ascent is light and compact, making it easy to pack on and off the trail. Between the hood, oversized draft collar and zipped draft tube, it’s guaranteed to keep body heat where it should be. Paired with the brand’s matching sleep pads, and you’ve got yourself a sleep system you’ll never want to leave. What customers say: “This is a very comfortable and lightweight backpacking bag. The multiple zippers prevent mummy-bag-claustrophobia, and they provide enough ventilation to make this suitable for all four seasons. I especially appreciate the foot zip so I can keep my feet flexed when sleeping.” Pros More room between hips and knees compared to a mummy sleeping bag Internal pocket Temperature rating of 0-25°F depending on model 750+ Fill, down certified Responsible Down Standard (RDS) Cons Some reviewers claim zipper pulls are small Shop Now The North Face, Eco Trail Down 20 — $189.00 This budget-friendlier down sleeping bag is another great option for fall and early winter camping trips. It features the brand’s recycled 600-fill down that stays warm while leaving behind a limited carbon footprint. As for the features, there’s a cinch-able hood, a vaulted footbox, and extended space at the knees for more room. It’s available in short, regular, tall and extra tall sizes, too. What customers say: “Nice construction and it fluffed up immediately. I’m 5′ 11” inches and the regular fit me perfectly. Any taller and I would get the larger one. I will likely order another one soon.” Pros 75 percent recycled materials Temperature rating of 20°F Extended width at knees Affordable Cons Only one zipper, and it doesn’t extend all the way to the feet Shop Now Feathered Friends, Egret YF 20/30 Women's Sleeping Bag — $429.00 Feathered Friends is a trusted brand in the outdoors industry for its high-quality and long-lasting line of down products. The Egret is no different—it’s filled with 900+ premium goose down (that’s ethically sourced and traceable) that’ll keep you warm and cozy on even the coldest nights. Like the others, it’s featherlight and packable while never compromising warmth. What customers say: “Even in the coldest temperatures, this bag works well just thrown over me as a blanket (and I like to sleep warm). It breaths well and doesn’t weigh me down. I’m 5’1’’ and fit well into a small. I love not having to carry the extra length. I wouldn’t sleep with anything else.” Pros Temperature rating of 20°F 900+ fill power goose down, extra down in the footbox and around the chest Extra room around elbows and knees Cons Shallow hood No draft collar Larger size only accommodates people up to 5’9″ Shop Now Nemo Equipment, Disco Women's Down Sleeping Bag 30°F — $280.00 The trouble with mummy sleeping bags is they’re not designed to accommodate side sleepers. Enter: the Disco by Nemo Equipment, which harnesses a curvy spoon-shape to let side-sleepers snooze comfortably. As for warmth, the 600-fill ethically sourced down is rated for 30-degrees Fahrenheit, so it’s ideal for warmer temperatures. It’s also feature-friendly, crafted with details that make a difference, like its Thermo Gills, which maximize airflow without letting drafts in, or its built-in Fillo, which can be stuffed with clothes and other soft valuables and used as a pillow. What customers say: “Just spent 2 nights in it this weekend and it’s the best sleep I’ve got in a sleeping bag. Very warm, extremely comfortable with the hood and built in pillow holder. It also packs down very small and it responsibly light weight! 10/10 would buy again.” Pros Spoon shape is ideal for side sleepers Waterproof and breathable footbox Integrated pillow pocket Cons Doesn’t have as low of a temperature rating as some of the others Shop Now Big Agnes, Camp Robber Bedroll — $200.00 Double-down on snuggliness with this double sleeping bag by Big Agnes. It’s designed to fit over your matching sleeping pad for warmth, complete with a stretchy sleeve that keeps your pad in place while maximizing thermal regulation. As for the bag itself, the temperature rating starts at 40 degrees (but the extra body heat from your partner will likely add warmth.) Or, if you’re alone, it’s large enough to wrap around yourself for twice the comfort. What customers say: “We only wish we had bought this sooner! It fits perfectly around our two big agnes sleeping mats and holds them together so tightly that there is no gap in between. Super warm at night and if it gets too warm, it easily zips on each side to hang a leg out,” Moosejaw customer Pros Feels more like a bed than a traditional sleeping bag Can be used as a sleeping bag or unzipped as a quilt Comes in single or double sizes Cons Bigger and less fitted around the body No hood and wide neck area Only for slightly warmer temps Shop Now REI Co-Op, Magma 15°F Sleeping Bag — $389.00 The Magma 15 from REI is a favorite amongst campers and backpackers, thanks to its ability to pack light without compromising comfort at night. The 850-fill is stabilized by the baffling which keeps it in place to maintain comfort all night long. It’s also loaded with features that aid in sleep quality and convenience, like the internal stuff stack for storing personals and anti-snag zipper for better zipping. What customers say: “This sleeping bag is awesome! It packs small and keeps me toasty. Went backpacking in damp ~30F weather and it kept me warm. I especially like the little scarf near the neck to keep cold air out.” Pros 850-fill goose down Temperature rating of 17°F Two hood drawcords Easy zipper access along shoulders and torso Cons Narrow around shoulders and hips Shop Now Therm-A-Rest, Vesper Quilt: 32°F — $330.00 Technically, the Vesper isn’t a sleeping bag—it’s a quilt that snaps around your body while the built-in foot box keeps you snug. The 900-fill is hydrophobic and quick-drying, while the internal lining reflects body heat, preventing heat from escaping. Best part is, it rolls down to the size of a water bottle, making it ridiculously easy to pack out on hikes where space (and weight) is limited. What customers say: “Best nights of sleep I’ve ever had in the Sierras. Spent four nights in the Kings Canyon area in late June. We had relatively warm nights, except for the night we spent at about 10,500′. Even that night I just layered clothing and slept like a baby.” Pros 900-fill down Super lightweight (under one pound) and compact ThermaCapture lining reflects body heat Water-resistant shell keeps it lofty even in wet weather Cons Only for use in warmer temps (temperature rating of 41°F) No hood or draft collar Shop Now
