Onyx Cool Back/Hip+, Black 58°

The onyx cool 58 back/hip is made with a specially formulated plant-based cooling phase material (pcm) contained in a wearable therapeutic wrap. The anatomic design conforms naturally to the body to relieve pain and draw heat and inflammation away from injuries. This cool (not too cold) device is safe to wear directly on the skin without risk of ice burn, frost bite or vasoconstriction. Maintains constant 58 cooling for about an hour, depending on use. Re-cools in the refrigerator in 30 minutes. Straps adjust to fit most body types.
