This baby is Patagonia's warmest, completely weather-resistant insulated and hooded jacket. The durable 3.5-oz ripstop polyester shell fabric has a Deluge® DWR (durable water repellent) finish and houses 200-g Quallofil® insulation that’s favored for its lightweight compressibility and ability to maintain warmth even in wet conditions. Detailing further provides comfort and defies the elements: the diamond-quilted construction reduces bulk and maintains an even warmth; the polyester nylon lining glides smoothly over layers; the head-hugging elasticized hood is warm and super soft; elasticized cuffs secure the fit and seal out cold; the zipper has a full-length wind flap and a zipper garage to eliminate chin chafe; 2-layer elbow and pocket panels prevent wet-through and add abrasion-resistance. With cozy, patched handwarmer pockets and a hand-me-down ID label inside.
