This is the personal heating system that installs in any jacket or coat to enjoy extra warmth no matter what one is wearing. Easily switched between a ski jacket used on the slopes and a formal overcoat worn to a business meeting, this reusable system consists of two sets of installation pads and a three-panelled belt of heaters. Simply affix the pads to the linings of two different jackets. The slim belt of heaters attaches to these pads to warm the core in cold weather. Its three temperature settings are easily selected via the power button, emitting heat ranging from 90° F to 135° F, and a full charge of the rechargeable battery provides up to four hours of comfort. Unisex sizes S, M, or L. (13 oz.)
