Onyx Cool Knee, Black 58° (Discontinued)

The onyx cool 58 knee is made with a specially formulated plant-based phase material (pcm) contained in a wearable therapeutic wrap. The anatomic design conforms comfortably to your leg to relieve pain and draw heat and inflammation away from injuries. May also be worn for compression support. 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.
