Cosmic 0 Sleeping Bag

Out-of-this-world-comfort while camping doesn't have to cost you an arm and a leg. Queue up the Kelty Cosmic 0 Sleeping Bag: an affordable and versatile sleeping bag that performs just as well during the colder months as it does in the high country come middle of the summer. Not only is the Cosmic relatively lightweight and highly compressible, but it also features Hydrophobic DriDown insulation, which is designed to retain insulating properties—even if the bag happens to get wet. Ultimately, this technology offers added defense against the build-up of moisture within your tent and makes the Cosmic ideal for inclement, unpredictable conditions. A standard mummy bag shape maximizes the thermal efficiency—meaning the bag is equal parts breathable and warm—while a draft tube prevents warm air from escaping out of the dual-sliding, locking zipper. The thermal comfort hood keeps your melon cozy, and the the natural fit footbox lets your feet enjoy an un-cramped night's sleep.

Good quality bag but mis-rated

I've used it once or twice and have initial impressions
True to size

The bag is very well made and great quality. However, it should definitely not be rated as a zero degree bag. I used this on a 30 degree night and was freezing all night even though I was wearing awool base layer, micro grid hoodie, and down puffy.

>Rating: 4

This is a men’s sleeping bag

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

This is a men’s sleeping bag and should be labeled as one. Currently the bag falls under the “unisex” category, but even the regular is too long for me.


Kelty Cosmic Down Series Overview

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.
