Built for big mountain expeditions and frigid conditions, the Ptarmigan is one of the lightest and warmest bags around. We combined the finest materials, including the cutting-edge Pertex® Shield Air fabric, and our time tested design to bring you a bag that can handle the rigors of mountaineering use and provide a warm respite at the end of a long day.
We send more Ptarmigan sleeping bags to Denali than any other bag we make.
