This waterproof/breathable, cross-seasonal trench coat is fully seam-sealed for maximum weather protection. It's also windproof, and the lightweight ripstop polyester shell has a durable, water-repellent finish that causes moisture to bead and roll off rather than soak into the fabric. A button-in insulated liner provides essential warmth when the temperature drops.NOTE: Temperature ratings are based on a controlled laboratory test, using low and moderate activity levels. 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."
