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.
Highly breathable, water-resistant shell protects the down insulation from frost, condensation, and spindrift
Ultra-premium 850-fill down insulation retains your body’s warmth and provides a higher warmth-to-weight ratio than any synthetic-fill insulation
Interlocking draft tubes and a down-filled collar prevent energy-sucking drafts from zapping your slumber
Wider shoulder girth allows for extra layering in brutally cold environments
Western Mountaineering bags are made in the USA
