Fenwick Liquid Titanium Therapeutic Leg Wraps are made of lightweight, breathable, drug-free liquid titanium fabric. Because the horse’s body contains titanium, the horse’s circulatory system is naturally stimulated when it comes in contact with another source of titanium, such as this therapeutic leg wrap. This generates far infrared rays (FIR) which increase circulation and help the body’s cells expel toxins. Fenwick’s wraps can be worn under bandages or polo wraps with no adverse effects because the process will only work with the body when needed. Unlike many other therapeutic bandages, Fenwick's can be left on 24 hours per day, seven days per week. Pair.
