Simply the best

Western Mountaineering makes sleeping bags, and not much else. THIS is what they do – they make the world's best sleeping bags.

If you want the absolute warmest bag on the planet, THIS is the bag to buy. Other manufacturers make "-40" bags, but no one packs as much down into their bags as Western Mountaineering. They cost a bit more, but you're paying for more down. More down = warmer bag.

more down, for more down :P

A great bag to be sure, but not quite up to Feathered Friends Snowy Owl

TOTALLY AGREE with oldguy68, you are absolutely CORRECT!!! ...Feathered Friends Snowy Owl is much better, in both packability and performance. The Bison is definitely NOT packable due to the Gortex material used on its system. I am also loving VALANDRE Thor, by the way. I am wondering if there is a Skandinavian bag out there that would out perform the Snowy Owl, the Swedish manufacturer has been known to have a very smart design and quality.
