About this product

The Kelty Cosmic 20 Sleeping Bag is a three-season sleeping bag designed for outdoor use, rated to withstand temperatures as low as 20°F with an ISO comfort rating of 32°F. It features 550-fill duck down that provides excellent insulation while remaining lightweight and compressible. The trapezoidal baffle construction prevents down from shifting, ensuring consistent warmth throughout the night. A half-length zipper with a draft tube minimizes cold air infiltration, and the natural-fit footbox offers room for comfortable foot positioning. An internal stash pocket keeps essentials like a phone or headlamp accessible and warm. The outer shell is made of 20D nylon with PFC-free DWR treatment, and the lining is 50D polyester. Machine washable and imported.
