The bitter cold of winter is slowly creeping up, and no matter how many layers we pile on, the chill seems to cut right through. Made for surfers, Quiksilver's Cypher PS+ heat-vest system uses far-infrared fibers, which throw your body's heat right back at it, to keep your core warm. The flexible heating pads placed over your kidneys are helped by a rechargeable battery. So you don't paddle through the frigid waters off Patagonia? The Cypher PS+ is also perfect for early-morning jogs or games at Lambeau Field.
