Western Mountaineering - Puma GWS

The sizable Western Mountaineering Puma GWS 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 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.

Product Reviews

If you're not willing to compromise, this is your bag
There are a few good bags out there that will cost less than this bag, but if you're after the best you can get and don't want to sacrifice any performance, you will be very happy with this bag. Construction is solid and it packs down well (stuffing it inside out will help). In terms of warmth it performs better than any other similarly rated bag I've tried (although I am not able to compare it to Feathered Friends as I've not owned one of their bags). I was going to go with the MF shell at first, but once of compared the feel of the two I just wasn't comfortable with the ruggedness of the MF shell. So I went with the GoreWindStopper shell, and I have to say I'm glad I did. There are times when it gets pretty moist in the tent on winter trips, and I've never had any issues with the down getting wet in this bag, and I'll even sleep with damp clothes inside the bag in order to dry them out at night, and it has worked very well thus far without any loss of loft. I do make sure to wash the bag at least once a year with a very thorough rinse, and I think that makes a big difference in the long run.

I'm 5'11" and I went with the 6' bag after trying them both out. I still have room for my boot liners and some clothing if I need it, but I also sleep on my back without much tossing around. I wouldn't want the extra space at the foot for my purposes, but some may, and I don't think it would detract from the warmth of the bag at all, but I'm not certain how that works. Review by Tomahawk
very very warm true to rateing -25
I have one of these with the {OVERFILL OPTION } must order
