Itâs 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. Models shown are 5â9â³ to 5â11â tall, wearing size S/4, L/12, or XXL/18.
