The Big Agnes Bolten SL 20 Degree Sleeping Bag is a superlight sleeping bag for backpacking adventures. Technical prowess comes in the form of a mummy shaped bag, filled with PrimaLoft® Silver and Gold Insulation Active. The combination nylon rip-stop and Polyester Spandex stretch fabric shell not only keeps the insulation in check, but allows you to move in your sleep. Talk about a shining star for all the side sleepers out there.
