Perfect for tent camping and winter mountaineering. With a large 75L capacity, it can hold a tent, pot, Primus stove, sleeping set, down jacket and pants, food, water, and more. I've been carefully storing it since using it for a 3-night trip on Mount Miyanoura. I'm selling it to someone who can use it for mountain climbing. The inside has become sticky with age, but I've been using it with a large, city-approved flammable bag as a liner to protect the contents.
