The Heated Vest.

Using carbon fiber technology powered by compact and unobtrusive rechargeable batteries, this heated vest generates four consecutive hours of warmth and, if necessary, can easily fit underneath a coat, providing adjustable warmth for a variety of comfort levels. It uses safe, low-power infrared rays to transmit heat throughout the carbon fiber mesh sewn into the vest. Batteries recharge (charger included) in five hours and can be removed to machine wash the vest. Made of imported 100% polyester fleece. Black, reversible to Gray. Specify unisex sizes M (38-41), L (42-45), or XL (46-49). Imported. (3 1/4 lbs.)
