No matter what kind of weather winter throws at you, this parka has you covered. Waterproof/breathable recycled nylon shell turns away rain, sleet, snow, or hail. The Premium Down insulation keeps you warm even when the mercury goes subzero. Inner, rib-knit storm cuffs further seal out the cold. NOTE: Temperature ratings are based on a controlled laboratory test by an independent university lab. Also consider: your sensitivity to cold and wind-chill; time of exposure; activity level; and use of layering.
