Fully seam-sealed construction plus ultralight, ultrawarm Premium Down insulation ensure maximum comfort. The nylon or polyester shell has a super-durable, water-repellent finish that causes moisture to bead and roll off rather than soak into the fabric. Adjustable, insulated hood has a removable faux fur ruff. 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.
