ICE and HOT WRAPS are fully adjustable to any part of the body. May be used for both ice and thermal therapy. Ice therapy reduces inflammation following injury or surgery. Thermal therapy helps promotes soothing relief from tired, aching, injured muscles. Re-usage Gel Pack is covered by our exclusive state-of-the-art, closed-cell neoprene, laminated with "outergrid" nylon to ensure long-wear durability. Hook and loop closure keeps wraps firmly in place yet allows complete rage of motion during treatment.
