The Kelty Cosmic Ultra 20° sleeping bag is our classic best-seller, striking the perfect balance of lightweight warmth. A trapezoidal baffle construction is one of the reasons the Cosmic line remains a favorite three-season superstar, with 800-fill DriDown providing lofty, packable warmth even if it gets damp.
A full draft tube with dual locking sliders and anti-snag treatment gives venting versatility, while a 0° full draft collar and 20° upper draft collar work together to retain heat. A zippered internal stash pocket keeps devices close at hand, and an expanded, natural-fit footbox gives more room to wiggle your toes.
Fully recycled shell and liner fabrics feature a PFAS-free DWR finish, and a stuff sack is included for quick, easy departures.
