Typically, the first few seconds spent inside a sleeping bag indicate the overall quality of the night about to come. Backside bags – warm, roomy, responsive to your every movement – adapt to the bedtime needs of the moment. Built for recreational activity, ambient temperature, your body size and your preference in added features, Blackside washable bags fit you. They fit the way you live your life outdoors. Like, as the Eskimos say, a particularly good glove.
