The Force Ten Endurance 1300 is a big down bag for very cold climates. A carefully designed combination of vertical, trapezoidal and chevron baffles keep the Endurance's 95/5 goose down insulation where it works best, rather than settling to the side of the body leaving cold areas. Additional layers of Insulite® Aero synthetic insulation at the head, chest and foot further enhance the heat retention of the bag, and will continue to do so even if the bag gets wet.
