The Arc'teryx Men's Therme GORE-TEX® Parka is a truly waterproof and windproof GORE-TEX® cotton like face fabric creates a streamlined look that gives warmth and weather protection on the harshest days. Down Contour Construction™ allows the down to form to the body, delivering more efficient thermal performance. Down Composite Mapping™ effectively places down and synthetic insulation where they deliver the most benefit. Lofty, high performance 750 fill power European goose down lines the core and sleeves where warmth is most needed. Coreloft™ synthetic insulation is used at the cuffs, hood and under the arms, areas prone to contact with moisture. Internal cuff gaskets seal out drafts and enhance comfort. It also features updated style lines for a more relaxed fit, a two-way WaterTight™ Vislon zipper with a snap placket, and synthetically insulated hood and neck gasket for additional warmth.
