The Apache MF 15 Degree Sleeping Bag (6'0")  is built with attitude. The Apache won't take no for an answer as it willingly pushes the bounds of a 2-3 season bag. It has a full 3-Dimensionally sewn down filled collar to seal in heat when your trip turns a little bitter. The efficient cut lets you heat the bag quickly and gives you a lighter parcel to carry. 19 oz of high lofting down pumps up a durable 6" of loft. The MicroLite XP shell is very weather resistant while remaining extremely breathable. At a total weight of 2 lbs. you'll be amazed just how much cold these bags will tame.
