(Back on Track) This therapeutic horse leg wrap 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, ligaments, tendons and joints. Used for both injury prevention as well as injury recovery. No liniment is needed. You can also replace poultice with these leg wraps. The bandages take down swelling in the horse's legs in just a few days and also can get wind puffs to be softer or can reduce them completely. The pillow wrap bandage is designed to be used with standing bandages. Material is a cotton/polyester blend infused with Back on Track's revolutionary new ceramic infused fiber. Back on Track products are not to be compared with magnetic therapy. This therapy works with your horses own body heat. Sold as pair.
