The Therapeutic Equine Shoulder Guard from Back on Track is designed to optimize freedom of movement in the horses shoulders, as well as minimize the rubbing and chafing that can be caused by blankets. The Shoulder Guard is made with state-of-the-art Welltex Technology material, which reflects your horses own body energy, creating a soothing infrared thermal effect. This effect may increase blood circulation, helping your horses muscles recover, stay loose, and become less inflamed. Our horse shoulder guard has removable pads that fit across the chest and on both sides of the withers to ensure total protection and comfort. It slips overhead and has a hook and loop belly strap to help keep the guard snug to your horses body. When selecting your horses size for a shoulder guard, this should match the size of the Back on Track blanket you are using on your horse.
