Bison Gore Infinium Western Mountaineering

Bison Gore Infinium Western Mountaineering is for Denali, Aconcagua, Himalaya… mountaineering in its extreme sense.

These are places where mistakes cannot be made and so the Bison is most often chosen to serve.

Gore-Tex Infinium fabric makes this bag impervious to the elements while remaining lightweight and very compressible.

Crammed with 42 ounces of 850+ fill power down this bag has 10 abundant inches of heat trapping loft.

Huge V-Block Side Baffles and horizontal baffles across your chest keep the down fill in place.

Double Interlocking Draft Tubes and a down filled Gore-Tex Infinium collar seal in heat and security while howling winds surround your tent.

The massive hood is not only well filled but is completely made with Gore-Tex Infinium fabric and has a large integral hood ruff to seal your face from the elements.

The Bison is the crowning glory of Western Mountaineering and demonstrates their commitment to innovation and quality.
