Bio-Magnetic therapy belts are some of the most innovative and advanced back supports on the market today. They are very versatile and specifically designed to provide excellent support, warmth and comfort to the lumbo-sacral area of the spine. Two inside pockets (one in the back and one in the front ) are designed to hold optional thermoplastic moldable inserts or hot/cold compresses. Two additional side pulls are designed to provide better fitting and tension adjustment. Breathable elastic helps minimize sweating and reduces allergic skin reactions. Highly recommended by doctors for rehabilitation and treatment after serious lower back injuries, surgeries and for reducing pain.
