A revolutionary gel sleeve surrounds the treatment area and delivers soothing comfort and compression, while helping to relieve pain and swelling. This product has multiple uses: freeze, refrigerate, hot water or microwave safe. A durable clinical grade polyurethane gel sleeve ensures the contents remain flexible and conform to body contours. The easy roll-on design allows for hands free application. Non-toxic, latex-free sleeve includes a cotton compression sleeve to prevent direct contact to skin.
