The Kelty Cosmic 40°F Sleeping Bag is our ticket to restful nights under the stars. Engineered for three-season comfort, this mummy-style bag is crafted with CirroLoft insulation, delivering lightweight, compressible warmth that doesn't weigh us down. Its buttery-soft nylon shell is treated for -friendly water resistance, and the silky taffeta liner adds a touch of luxury to every night in the backcountry. The bag features an offset quilt construction to eliminate cold spots, a contoured hood for a snug fit, and an expanded foot box for extra room to stretch and wiggle our toes. Thoughtful details like a zippered internal stash pocket and anti-snag sliders ensure convenience on the trail.
