Ponderosa MF

$720.00 - $765.00


A big warm semi-rectangular bag with 7" of loft; 15° F

If you're on the larger side, or you just don't like being stuffed into a narrow mummy bag, the Western Mountaineering Ponderosa MF is the way to go. Sporting 67 inches of girth at the shoulder and 48 inches at the foot, the Ponderosa offers acres of comfort for a full three seasons; depending on your size, you can enjoy this sleeping bag down to 15º F (the bigger you are, the warmer it will feel). The Ponderosa MF zips to any Western Mountaineering mummy bag, and if the nights are really mild, unzip the bag around the foot and mate it with their Summer Coupler. The Ponderosa is also available in a 7' length.

Like all of Western Mountaineering's bags, the Ponderosa MF 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.
