Digital Moist Heating Pads for Neck and Shoulder are the first medical grade electric moist heating pad available to the public. Digital moist heating pads as opposed to dry forms of heat draws moisture from the air and retains it in specially designed high-grade ceramic heating element cells and delivers that moist heat deep into your muscle tissue for maximum relief similar to a deep tissue or shiatsu massage. The pad is constructed from double stitched 100 premium grade durable corduroy with a soft plush flannel cover for ultimate durability and comfort.The Thermotech contains a light spray on carbon mineral that emits a natural infrared wave form and is thereby pushed into the tissue by the electric heat produced by the product.
