Cosmic Synthetic 40°F Sleeping Bag

Mummy-style sleeping bag that finds the perfect balance between weight and warmth

Balancing weight and warmth, this mummy-style sleeping bag is both light on weight and easy on your wallet. Synthetic insulation provides lightweight, compressible warmth and nylon taffeta fabric feels as soft as silk. It’s a great option all summer long and warm enough for camping in late spring or early autumn too. The roomy footbox gives you more room to wriggle your toes and there’s a handy stash pocket for your phone too, to help keep it warm and prolong battery life.
