15 degrees of shoulder-season boundary-pushing; narrow cut

The Western Mountaineering Apache MF is built with attitude! This water-resistant, lightweight, and breathable 15° F bag won't take no for an answer as it pushes the bounds of what a late-summer/early-fall bag can do. A full 3-dimensionally sewn down-filled collar seals in heat when the weather takes a turn for the worse. The slim, heat-efficient cut lets you warm up the bag quickly and makes for a light, compressible package. 19 oz. of high lofting down pumps up a durable 6" of loft. At a total weight of around 2 lbs, you'll be amazed just how much cold these bags will tame.

Like all of Western Mountaineering's bags, the Apache 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.
