The Kelty Cosmic 40 Sleeping Bag provides lightweight warmth and maximum comfort from spring through fall. The bag is cut with generous room around and shoulders and feet, with an expanded natural-fit footbox that allows our toes to wiggle while we sleep. The 550-fill down is light and lofty, trapping warmth to keep us sleeping soundly on cooler nights, and the two-way zippers allow us to keep hot air moving through the warmer months. The bag has an internal stash pocket that allows us to keep track of our phone, watch, or headlamp while we sleep, and packs down small in the included stuff sack for quick overnight adventures.
