This is the new down insulated version of one of the most popular, versatile, and all around waterproof/breathable GORE-TEX® shell jackets from Arc'teryx.  This is also partially a hybrid insulated parka that uses some Coreloft™ synthetic insulation in moisture prone areas.  Stay dry and stay warm.  Arc'teryx says that this is their most versatile down insulated GORE-TEX® mountain parka.  A great choice for most cold weather mountain adventures.  Use this for things like mountaineering, backcountry skiing and snowboarding, lift assisted ski days, as a climbing belay parka, a summit parka, for ski mountaineering, for overnight snow camping, or to throw on during breaks on winter hikes and snowshoe outings.  A perfect blend of warmth, waterproofness, durability, and comfort when encountering cold, snowy, windy, and extremely variable weather conditions.  It's sooooo nice to wear your lightweight breathable layers on the way up, and then have just one comfy layer that is both warm and waterproof waiting in the top of your pack to throw on whenever you stop.  Features includes 40D GORE-TEX® outer shell fabric, 850 fill goose down insulation, ventilating pit zippers, and a helmet compatible StormHood™.  This will probably also become your favorite go-to jacket for mid-winter cold days and nights around town.  Take good care of this coat, and it will take good care of you for a lifetime.
