The Alpha Lightweight Parka from Arc'teryx is a premier belay and summit parka made with lightweight but highly durable 2-layer GORE-TEX INFINIUM™ with Hadron™ face fabric and is insulated with 850-fill power RDS-certified goose down that is combined with Coreloft™ Compact 40 polyester synthetic insulation in moisture prone areas. Windpoof, warm, and extremely water repellent while remaining highly breathable and extremely compressible and packable.  The perfect piece to stuff into the very top of your pack for immediate quick access at belays, on the summit, during rest periods, or while transitioning or descending in cold winter conditions.  Other features include an insulated helmet compatible StormHood™, two zippered hand pockets, two internal dump pockets, and a zippered chest pocket.
