Western Mountaineering Puma Super MF Sleeping Bag: -25F Down Royal Blue, 6ft in/Right Zip

The Western Mountaineering Puma Super MF Sleeping Bag is a solid choice for mountaineers bold enough to take on Old Man Winter at his strongest. Interlocking draft tubes deflect creeping cold and work in conjunction with the nine-inch loft and 36 ounces of 850+ down fill to give the Puma Super MF a monstrously warm -25 degree rating.
