Cypress GWS

$1,225.00 - $1,265.00


Wide-cut, windproof and highly water-resistant -30° F bag

Until the Western Mountaineering Cypress GWS came along, most sleeping bags designed for extreme cold had been narrow mummy bags. The -30° F sleeping bag is incredibly wide, with more insulation and girth than any other bag in its warmth range. Even though this is not a mummy bag, it is absolutely capable of keeping you warm in severe cold. With an average loft of 11" and packed with a whopping 50 ounces of down, this bag will completely envelop your body with a thick barrier of the best thermal protection available, Western's 850+ fill premium goose down. Features include a stout insulated draft tube inside the zipper combined with a second storm flap covering the outside of the zipper, a full Gore Windstopper™ water-resistant/breathable shell, a three-dimensional insulated draft collar, and a second zipper allowing the bag to open up completely around the foot.

Like all Western Mountaineering sleeping bags, this -30° F sleeping bag is made by hand in San Jose, California. Their down is sourced from free-range mother geese who are never live-plucked or force-fed.
