DESCRIPTION

Forty below zero is a magical place where Fahrenheit and Celsius intersect, as well as an incomprehensible icy hell that can suck the life force right out of you. Come prepared to do battle with the epic cold thanks to the Western Mountaineering Bison Gore WS Sleeping Bag. An extremely weather-resistant Gore WindStopper shell and a whopping forty two ounces of premium 850-fill goose down let you hunker down when the temperature plummets to ungodly lows, and you can trust in the V-Block side baffles, double interlocking draft tubes, and insulated hood and collar to seal out the chill in the big mountains. When the difference between life and death comes down to your sleeping bag, the Bison doesn't compromise.
