Onyx Cool Shoulder

The Onyx Cool Shoulder features a plant-based phase change material that cools to a skin-safe and soothing 58 degrees.

Cooling PCM safely permeates tissues to relieve pain and draw heat and inflammation away. Maintains constant 58 degrees cooling for about an hour depending on use.
