Kelty Cosmic Down 0 Sleeping Bag - Regular

The Cosmic Down 0 is the coldest-rated model in Kelty's long-running Cosmic Down range, taking the same award-winning trapezoidal-baffle design down to -18C for winter and shoulder-season use. This Regular version fits sleepers up to 183cm. The trapezoidal baffles hold the 550-fill DriDown more efficiently than standard baffles for extra warmth, while the water-resistant DriDown treatment keeps the down lofting in damp conditions - all in fully recycled fabrics with a PFAS-free DWR.
