The Back on Track® Wrist Brace is comprised of a Polyester/Welltex® infusion which provides mild compression and works with your body to stimulate circulation. Back On Track’s Welltex® technology is a therapeutic fabric, which can help increase the micro-circulation of the blood and oxygen delivery when worn against the skin. When a Welltex® product is used, the energy produced by the body is absorbed by the ceramic minerals in the fabric’s thread and translated back to the body as Far Infrared energy waves.
