The Pertex® Shield fabric membrane offers waterproof/breathable protection from Mother Nature’s mood swings, while lofty 800-fill-power-down insulation keeps you warm in plunging temps. When it’s time to call it a day, give your feet a break in the 11-baffle wrap-around footbox with reinforced lining for extra comfort. Its stretch tricot cross-baffle construction controls down shifting and eliminates cold spots. The down-filled draft tube and collar, nautilus 6-baffle hood, and zipper guards limit heat loss in the most extreme conditions, so you never have to turn back.
