True to its name, the Kelty Cosmic 20 Sleeping Bag loves being out under the stars. From campgrounds by the lake to weekend backpacking treks in the mountains, you've got three-season performance to keep you warm on chilly nights wherever you rest your head. It's filled with lightweight and packable 600-fill down that not only insulates well, but resists moisture to keep you warmer when things get a bit damp. Whether you're trekking through drizzly weather or surviving the damp cold, your down will stay dry for longer and keep its loft better when wet. Its thermal-comfort hood wraps your head in snug warmth on cool nights, a natural fit footbox ensures that your feet don't feel trapped or uncomfortable while you sleep, and a draft tube along the zipper ensures that the cold stays out.
