Kelty Cosmic Down 20 Degree 550 Fill Down Sleeping Bag
The Kelty Cosmic Down 20 is the sleeping bag that has introduced a generation of campers to down insulation without the down price tag. Rated to 20°F with an ISO comfort rating of 32°F, this is a true three-season bag that handles cold spring mornings and late-fall nights. The 550-fill DriDown stays warm even when damp, and the trapezoidal baffle construction prevents cold spots by keeping the down evenly distributed. A roomy footbox gives your toes wiggle room, recycled fabrics keep the environmental footprint low, and the included compression stuff sack packs it down to the size of a football. It is the bag you grab for car camping, cabin trips, sleepovers, and entry-level backpacking — versatile enough to be your only sleeping bag.
