Puma GWS

$1,025.00 - $1,080.00


Extreme warmth with a GORE® shell; -25° F

The uber-cozy Western Mountaineering Puma GWS sleeping bag is stuffed with premium down, highly water-resistant, and roomy to boot! 37 ounces of 850+ fill power down lofts this bag to a full 9" for a rating of 25 below zero. A shoulder girth of 64 inches provides enough room to layer, store clothing or to fit larger folks. The inside footbox is sewn with durable 2.4 oz. fabric to protect the bag while stowing gear like boots and water bottles. The Puma's Reverse Differential Hood is roomy, down-filled and warm, and completely made with Gore Windstopper™. The full down-filled collar and both Interlocking Draft Tubes are also completely made with GWS fabric. Few continents require anything warmer than the Puma!

Like all of Western Mountaineering's down sleeping bags, the Puma GWS 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.
