Product Highlights

The Kelty Cosmic 0 Degree sleeping bag is designed for winter or cold-weather backpacking and camping. Compressible synthetic fill and a tapered mummy cut make the Cosmic 0 Degree a thermally efficient option for 4-season use.

The Cosmic 0 Degree sleeping bag is insulated with Kelty CloudLoft Pro insulation, a lightweight, compressible synthetic fill that maintains its high loft, softness and insulating properties over time. Unlike down fill, Kelty CloudLoft Pro retains most of its insulating capabilities even when wet, making the Cosmic 0 Degree bag a good choice for wet climates.

Two-layer offset quilt construction eliminates cold spots, keeping outside air from reaching the interior of the Cosmic 0 Degree bag. This type of quilt construction is durable and maintains its shape and structure even after many uses. A draft tube behind the 3/4-length, two-way locking zipper, an insulated top baffle collar and a contoured hood with an insulated hood baffle further enhance the thermal efficiency of the Cosmic 0 Degree bag. The hood utilizes Kelty's patented FatMan and Ribbon drawcords, allowing you to adjust the top or lower sections of the hood by feel even when it's dark outside. The shell of the sleeping bag is made of ripstop nylon and a polyester taffeta liner provides internal comfort.

Other features found on the Cosmic 0 Degree include sleeping pad security loops, internal liner loops and hanging loops.

The Kelty Cosmic 0 Degree sleeping bag is available in Reg (fits up to 6'0") and Long (up to 6'6") lengths. Each Cosmic 0 Degree bag includes a stuff sack.

Sizes available: Long Right Zipper, Regular Right Zipper

Kelty part numbers: 35413911LR, 35413911RR

  • Noall F. murray UT

    Likes: This bag really does keep you warm in the coldest temps. I have used this bag a number of times, lowest temps in the single digits, and have woken up the next day still nice and toasty.

    Dislikes: It is huge and difficult to compress.

  • Ed K. Myersville MD

    Likes: This sleeping bag seems very warm. A couple nights on the AT in a hammock, with temps down to the mid-30's and I was still too warm. Great bag for car camping.

    Dislikes: This thing is huge. Even in a compression sack it takes over half of my 70L pack. I knew it would be on the large size but dang!

  • Michael J. Lake Isabella CA

    Likes: extremely warm and well built.

    Dislikes: stuff sack is too big. when you roll up the bag it expand into the stuff sack. taking up too much room. but when used with an external frame backpack does not matter.
