Cosmic Down 20 Review

The sleeping bag is comfortable, packs well, and does the job. It was a great buy and am considering picking up a smaller version for my kids.

Not built for a Man.

Great bag... just not sized for an adult male. My 15yo daughter fits perfect. if you wear an XL shirt, look for another bag. I bought for motorcycle camping for myself due to the compactness and cold rating. Luckily, my daughter rides adv motorcycles too. She LOVES this bag! And I WILL be buying a Kelty Bag that I can fit in.

Geometry-Infused Warmth
Geometry isn't just for textbooks. The Kelty Cosmic 20 Degree Sleeping Bag uses trapezoidal baffle construction to ingeniously trap heat, making it a standout for your three-season adventures. Designed for the long sleeper, this bag extends the coziness from head to toe.

Sustainable Comfort All Night Long
Settle into the 550 Fill Down comfort of the Cosmic. It's more than just warm; it's responsibly warm with fully-recycled shell and liner fabrics and a PFAS-free DWR treatment for those dewy mornings. The long size ensures even the tallest campers can stretch out under the stars.

Smart Features for Outdoor Living
From the expanded footbox for your tired feet to a zippered internal stash pocket for your essentials, every detail is dialed in. Plus, the full draft tube and collar work to keep the chill out, and the quad-stitch anti-snag zipper means no fumbling when you're ready to tuck in.
