Light on the hike, reliable in rain.

Warmer nights and summers in the alpine call for the Kelty Cosmic 41 Sleeping Bag. Treated with DriDown, the Cosmic's light down insulation retains its lofty warmth when clouds creep overhead and rain starts dropping down your tent. A quilt-through construction and soft taffeta help you sleep soundly, like you were at home in bed. The thermal-comfort hood makes sure your ears aren't numb in the morning, and the footbox ensures a natural fit. Kelty added a draft tube down the full-length zipper to prevent brisk breezes from creeping in. FatMan and Ribbon drawcords give the hood, neck, and shoulders a snug fit.
