Vest uses battery power to keep warm

With snow all around and the mercury dropping like there's no tomorrow, it would be prudent to fork out a little bit of extra money for the Heated Vest to keep you warm and toasty all around without freezing to death whenever you go out. At $129.99 from Hammacher, the Heated Vest is made from polyester fleece and is reversible, essentially giving your two different styles within a single vest. It is thin enough to hug your body under a jacket, and uses an embedded carbon-fiber mesh and infrared heater to warm the fabric evenly, doing away with the need for messy wires or heating elements. The vest's rechargeable batteries offer up to 4 hours of continuous heating.
