10 Reviews: Best Lightweight Down Sleeping Bags (Jun 2023)

Ever imagined being able to get an ultralight down sleeping bag on a low-budget? Kelty Cosmic makes it possible! With a price tag of less than $ 200 and a temperature rating of 20 degrees, this mummy-shaped bag is capable of three-season backpacking. This sleeping bag is a stuffed with 600-fill Drawdown that keeps you warm as if you were in your own room. Not to mention the pocket to keep your essentials handy.

I took this out on an early fall trip to the southern part of the Adirondacks, and it was great. A bit warm on nights that were above 60, but that's expected with a bag rated for 20F. The stash pocket and lining are my favorite parts.

Featuring a generous size, the perk of having a Spoon™ shaped bag is the availability of a wider space than the mummy shape. It means that you can sleep in whatever style you want. This spacious value is certainly a gift for side sleepers who often have trouble in tight bags. When the temperature drops, Nemo Disco hugs you like a cocoon, but you can also unzip the ThermoGills to let out warm air.

Great bag, I have the large size, very comfortable with lots of room to toss and turn. I’m 6’ 3” 245 pounds and this is the only bag I have owned that doesn’t make me feel claustrophobic! Great weight and size for serious back packing.

Marmot has long been providing quality outdoor equipment. Marmot Phase is one of them. It’s filled with 850 fill power down which of course packs up small, making it an ideal outdoor companion. It will not make you feel a bit wet thanks to the moisture-resistant Down Defender. Get a toasty night’s rest no matter what the weather throws!

We bought this sleeping bag and the women’s Phase 20° sleeping bag and are SO happy with them. 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. We would definitely recommend this sleeping bag!

This mummy bag should be your consideration if you’re looking for lightweight sleeping gear. It is built with a top-notch quality that resists wear and tear. With comfort in mind, REI Magma provides a bit of extra space for the knees and feet which is perfect for resting your feet after a long journey. Rated at 15 degrees, this cocoon will keep you snug as a bug in a rug.

Went hiking at Mount Mitchell on the Black Mountain Crest Trail with temps below freezing and the windchill making it feel like single digits. This bag did really well keeping me warm and comfortable sleeping under a tarp. Its lightweight, warm, packs down well, and is great quality in my opinion. Looking forward to getting out with it through the fall and into winter.

This award-winning sleeping bag features a zipperless design for more comfort for users who often complain about stuck zippers. Weighing only 2 lb 8 oz, you can feel the warmth of home, supported by insulated hand and arm pockets. Plus, your feet finally get the perks they deserve: self-sealing foot vents for easy ventilation.

This is the best sleeping solution you can get. The sock for the pad, the vent for feet, and zipperless quilt make for best sleep you can get in the Backcountry. Love, love, love my Backcountry bed.

Next, we have the Flicker UL Quilt Sleeping Bag by Feathered Friends that gives everything you wish: maximum comfort, snug footbox, full center-zip, and 950+ goose down fill. Everything is designed without sacrificing weight, which is less than a pound and packs down to 8 liters. Still not enough? Small webbing loops are provided for use as a hammock under quilt.

The quality is amazing, I like the special touches like the snaps to create a draft collar, and the ones at the feet. Plus the put a snap at the top of the zipper to allow you to open the bag up to vent without losing the seal. Plus the loft on the bag is incredible. The handcrafted bag is top notch. Thank you again for building the perfect quilt/bag to keep me warm while hiking the PCT in March.

Weighing a mere 1 lb. 4 oz, this down feather packs down as small as 6 x 8 inches. Yep, it is remarkably light that you might doubt it will keep you warm, but it does. It is stuffed with 900+ Goose Down which makes it as comfy as a freshly made bed. It also comes with a storage sack complete with straps for easy carry.

This bag is the perfect addition to any gear arsenal and has transformed my pack weight. It’s extremely lightweight and packs down to nearly the size of my Jetboil, allowing for ample room in the bottom compartment of my pack. One of my favorite features is the straps at the bottom of the bag to secure it to your sleeping pad. 10/10 would recommend!

The Spark Ultralight Sleeping Bag offers a superior warmth-to-weight ratio with the help of its premium materials. Enjoy the sensation of living in a cocoon wrapped in a 10D UL nylon shell and soft liner that makes you refuse to wake up. The most jaw-dropping feature is the incredibly small packed size.

Super light, very warm Super light, very warm and fits in a small stuff sack. What more do you want? Took the Spark Ultralight Sleeping Bag on a 9-day bike tour and it worked perfectly. One night it got down to 35°. With my puffy jacket and SmartWool hat, I was toasty warm.

This down sleeping bag is designed for climbers, skiers, and backpackers with a temperature rating of 15 degrees Fahrenheit. What’s cool about this bag that is rarely found in other products is its glow-in-the-dark zipper pull that helps you get out of the nest when you wake up at night and want to do your duty. To ensure that your bag remains dry, Mountain Hardwear has coated the Phantom with a durable water repellent (DWR) finish.

... This thing is light, packs down small, and is super warm. I've been taking it backpacking here in CO this spring in weather between 25 degrees and 40 degrees. I think I have 7 nights in it so far. With a liner I think I could easily take it down to 0. It is also super comfortable and the fabric feels like silk. Foot box is huge and my feet are always toasty. The DWR is a nice touch. ...

Last in order but not of importance, Montbell’s Down Hugger will do it for you ecstatically. This down feather is designed with comfort in mind, ensuring there is no water or moisture sipping in your cozy cradle. Rather than giving you a wrap-around footbox, this hugger offers an adaptive stretch so there’s always room no matter how much you spread out at night.
