Kelty Sine 20° Sleeping Bag, Long

Kelty’s got your back during your next chilly night in the backcountry. With the Sine 20° DriDown 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 DriDown stays drier, lofts better, and dries faster. On warmer nights, leave unzipped and use like a blanket.
