550 Fill Power Down Mummy Sleeping Bag for Backpacking

The Kelty Cosmic 20 Sleeping Bag extends your camping season from spring through fall with reliable warmth and smart design. Rated to 20°F with a 32°F ISO comfort rating, this three-season bag keeps you comfortable when temperatures drop. The 550-fill duck down insulation compresses easily into the included stuff sack and stays light in your pack. Trapezoidal baffle construction prevents down from shifting so it keeps working where you need it most. A draft tube seals the half-length zipper against cold air, while the natural-fit footbox gives your feet room to relax. Dual sliding zippers let you vent heat when temperatures swing without fully unzipping. An internal stash pocket keeps your phone or headlamp warm and ready through the night. Built with 20D nylon shell and 50D polyester lining, this mummy-shaped bag handles the demands of extended camping without adding bulk to your kit.
