Core coldness is a problem no more with the Patagonia Down Sweater Vest. This vest could practically float with its simplistic features and no frills attitude. The 800-fill-power down seals in warmth and is ethically sourced and traceable. Its compactness can be seen when it is easily stuffed into an internal pocket. The exterior features a tear-proof shell with a DWR (durable water repellent) finish with wind and water protection. The drawcord hem seals in heat and can be accessed through the zippered handwarmer pockets, along wiht elastic armholes.
