This ergonomically shaped Exercise Rug Supreme is made of high-quality fleece material, lined with the revolutionary Welltex™ ceramic infused fabric, which works by providing soothing FAR infrared therapy that helps support circulation, alleviating tension with a calming, stimulating effect. The rug is shaped to fit the contours of the horse's back and is cut away to allow the rider's legs to stay in contact with the horse's side. This fleece exercise rug is ideal for riding in cold weather and keeping muscles warm during exercise.
