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.

Fantastic sleeping bag! Ultra warm bag for any winter or extreme cold. Also a perfect bag for anyone who is concerned about staying warm in cold weather. Its durable and intelligent construction with the highest quality materials is really something to experience when you have the benefit of 50+ years of using sleeping bags.
