By combining modern textile technology and traditional Chinese medicine which is supported by scientific studies, Back on Track creates products that help people, horses, and dogs achieve a more active and comfortable life. Back on Track's joint and muscle support products are all made of functional textiles with reflective properties, and the braces are FDA-approved. The textile is a synergy of ancient Chinese experience and modern scientific textile technology. During the manufacturing of polyester- or polyester fibers, our state-of-the art Welltex technology is infused into the fibers. When worn or used, these particles radiate an energy back towards the body. This reflection is long-wave radiation, which is also known as long wave infrared radiation.
