Cosmic 20 Sleeping Bag: 20 Degree Down

True to its name, the Kelty Cosmic 20 Sleeping Bag loves being out under the stars. From campgrounds by the lake to weekend backpacking treks in the mountains, you've got three-season performance to keep you warm on chilly nights wherever you rest your head. It's filled with lightweight and packable 600-fill down that not only insulates well, but resists moisture to keep you warmer when things get a bit damp. Whether you're trekking through drizzly weather or surviving the damp cold, your down will stay dry for longer and keep its loft better when wet. Its thermal-comfort hood wraps your head in snug warmth on cool nights, a natural fit footbox ensures that your feet don't feel trapped or uncomfortable while you sleep, and a draft tube along the zipper ensures that the cold stays out.

  • Versatile bag to keep you warm wherever chilly nights find you
  • Hydrophobic down lofts well even in damp conditions
  • Mummy design with hood wraps you in full-bodied warmth
  • Draft tube along the zipper keeps the cold from getting in
  • Included stuff sack lets you stuff it down small in your pack
  • Electronics pocket keeps phones and headlamps close by as you sleep

Not very warm

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: small

Bought this bag for a Moab trip, when I got it, it felt thin, but decided to take it anyway, night temps in Moab were in the low 40s, first night I was cold, I had to get up and put thermals on to sleep. This bag is not very good nor is it very well constructed, zippers are not easy and would snag while inside and trying to zip the bag closed. After two cold nights, I returned it as soon as I got home.

Wrong size

  • Size Bought: Am/Reg

Heads up.
Backcountry’s website says this short/ Reg bag fits a 6 footer. Not the case. The product itself says it fits uptown 5 foo 6 inches. But it looks like a 5’8” guy can fit in. Not me.

Super warm and lightweight

  • Familiarity: I've used it several times

Have used this now on various camping trips and it's super warm despite being so lightweight. It's definitely a winner in my books. The only issue is that the stuff sack provided does not compress the sleeping bag as small as it could be, not even close. So I bought a separate small stuff sack to make it more compact when camping and hiking.

Stef, I'm looking at getting this bag for backpacking. What size stuff sack did you get the back into? I like to carry a 50L pack and am hoping this bag will be small enough. Thanks!

Great for Utah camping.

    This bag is perfect for Utah summer nights in the mountains. It’s warm, comfortable, and lightweight.

    Roomy and sooo soft.

    • Familiarity: I've used it once or twice and have initial impressions

    Very comfortable, warm and roomy bag. I recently bought the Marmont 30 deg bag and felt confined / uncomfortable in it. The taper of the Cosmic bag is less agressive alowing more freedom of movement.

    Kelty Cosmic Down Series review

      An amazing update to this Best-Selling bag. It's lighter, softer, and more compressible than ever. All for a full down bag that is STILL well under $200.

      It would be much more helpful if the Shoulder and Hip girth measurements were included in the Tech Specs. There really isn't a way to compare this bag to others without having to go offsite to research and then have to come back.
