The superior comfort and sub-zero warmth of Premium Down is now even better. Bonded channels in this jacket eliminate sewn seams for maximum thermal efficiency, and the mechanical stretch of the polyester shell provides exceptional mobility. A durable, water-repellent finish causes moisture to bead and roll off rather than soak into the fabric. 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. Models shown are 5’9" to 5’11" tall, wearing size S/4, L/12, or XXL/18.
