Sine 20 Sleeping Bag

Kelty's got your back during your next chilly night in the backcountry. With the Sine 20degF DriDownTM Sleeping Bag, you get the best of both worlds of comfort and light on weight. The Arc Zipper System is there to provide a natural arm motion when opening the bag and for dual venting. The water resistant 800 fill DriDownTM stays drier, lofts better, and dries faster. On warmer nights, leave unzipped and use like a blanket.
