Kelty Supernova 40 Sleeping Bag: 40F Down

The Kelty Supernova 40 Sleeping Bag keeps us cozy as we camp in the mountains during the warm summer months, and its lightweight, packable construction allows it to moonlight on overnight backpacking trips. Packed with warm 550-fill down and cut with a roomy, semi-rectangular shape, this bag is made to comfortably accommodate a wide variety of sleeping positions while sheltering us from cool mountain nights.
