Introducing the new Ionic Therapy technology. The inner fabric of the rug is printed with the powdered form of a crystal called Tourmaline. Tourmaline releases Negative Ions, which cause a change in the water in the horses body, increasing blood flow to important areas such as muscles. This brings increased levels of oxygen to the muscles and helps to clear toxins from the body. Ideal for use before exercise to prepare muscles for work, and after, to help reduce any lactic acid build up caused by exercise.
