This women's Alpha Parka from Arc'teryx is their warmest down belay parka and combines a hybrid insulation of mainly 850 fill goose down with synthetic Coreloft™ insulation in moisture-prone areas.  The fabric is seam-taped and combines two types of 2-Layer GORE-TEX® INFINIUM™ fabrics, including extremely lightweight and strong 2-layer GORE-TEX® INFINIUM™ Hadron™ proprietary outer face fabric in high wear areas that is engineered with a liquid crystal polymer ripstop that makes this fabric as abrasion resistant as many other fabrics twice the weight.  The GORE-TEX® INFINIUM™ fabrics also block the wind while trapping and holding in more warmth than standard fabrics.  Other features include a helmet compatible insulated and adjustable StormHood™, two hand pockets, two internal dump pockets, a zippered chest pocket, full length climbing harness compatible double slider front zipper, and an adjustable hem drawcord.  Designed for extremely cold bivouacs and alpine belays.  This is the warmest women's specific down parka available at our Seattle mountaineering store.
