Product InformationThe Apache is built with attitude! It simply won?t take no for an answer as it willingly pushes the bounds of a 2-3 season bag. These bags have 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 about. 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. 1 oz. you?ll be amazed just how much cold these bags will tame.
