Abstract: Disclosed is a heat activated thermal garment utilizing a back brace for housing of a main controller element and a lithium palmer battery. The controller is used for monitoring and supplying power for up to eight pieces of resistively heated clothing strips that can be incorporated into medical therapeutic products, athletic wears and clothing lines. The heating strips are strategically positioned within the garments. In a preferred embodiment a wristwatch type thermostat controller is employed that is wirelessly coupled to the back brace mounted controller. The wristwatch allows direct control of temperatures at select positions in a garment.
