Exclusively from Hammacher Schlemmer, this vest that has built-in heating elements in the pockets. It uses virtually undetectable heating elements woven from carbon fibers--located in the two front pockets as well as the upper back--that are five times thinner than human hair. You can control either the pockets and the 5" x 5" back panel separately and you can adjust the level of heat for each. The microfleece fabric is windproof and traps heat close to the body. Its unobtrusive rechargeable battery provides up to seven hours of continuous use after a three-hour charge, and three heat settings are easily manipulated by a controller that stores comfortably in an interior pocket. Includes AC adapter. Slim fit; unisex sizes M (38-40). (3 lbs.)
