This battery-powered heated wrist wrap alleviates compression on the median nerve (the cause of carpal tunnel syndrome) without being tethered to a wall outlet. Unlike typical heating pads, the wrap produces infrared heat that penetrates deep into tissue and increases subcutaneous temperature by up to 2º F to stimulate blood circulation, relieve swelling, and improve the mobility of tendons and ligaments in the wrist. Made from neoprene and nylon, the flexible pad wraps comfortably around the wrist and allows freedom of movement. With three heat settings between 113º F and 140º F and an automatic shut-off after 60 minutes. Fits up to 10 1/2"-diameter wrists. Requires four AA batteries. 11 1/2" L x 3 1/2" H. (11 1/4 oz.)
