(Thermotex Therapy Systems) The Thermotex Therapeutic Hood utilizes 2 infrared pads. One pad is positioned on top of the forehead, midway between the eyes. The other pad is positioned mid-center beneath the jaw. The cover portion of the hood is 100% nylon with a polyurethane coating, and is washable. The infrared pads themselves are not washable or flexible, therefore should never be washed or bent. Adjustable high/low power settings. Velcro fasteners to adjust fit.
