Designed to tackle equine back problems particularly common in performance horses. Contoured design provides maximum coverage from the withers and shoulder blades, along the spine and over the Sacroiliac joint. Reusable FirstIce stays cold for over two hours allowing maximum penetration of cold therapy to deep muscle and connective tissue. May be used with all the packs or in isolated sections to target specific areas. They are made with Quadrispan anti migration fabric. The unique breathable fabric keeps the wraps in place on the horses leg and the ice compressed against the area being treated. Specially placed velcro closures allow for a secure tight fit every time. Removal is easy, no yanking or jerking on the tabs to undo.
