This therapeutic blanket uses state-of-the-art fabric, which contains polyester thread embedded with a fine ceramic powder. Designed to reflect the horse's own body-warmth, it creates a soothing far infrared thermal heat, which can help alleviate pain associated with inflamed muscles and joints. Used for both injury prevention as well as injury recovery. This blanket is helpful for any horse, but especially those with muscle problems in the shoulder or back. Also horses that have cold backs will benefit greatly. For best results leave on overnight; but may also be used to help warm up muscles prior to exercise. In a short time you will see and feel the results in the way your horse moves and acts. The Rime Blanket is designed with crossing belly surcingles. Back on Track products are not to be compared with magnetic therapy. Our form of therapy works with your horses own body heat. Material: Exterior-polyester/Interior-polypropylene blend infused with Back on Track's revolutionary new ceramic infused fiber. Weight: 160 grams
