The ThermiPaq hot and cold pain relief wrap uses a thermal ceramic compound made from all-natural, clay-based materials. The clay-based compound allows the pack to be easily molded and conforms to all parts of the body including the back, thighs and shoulders for effective pain relief. It absorbs hot and cold temperatures then slowly releases hot or cold therapy over an extended period of time allowing for deeper and more effective penetration. It includes a soft fleece sleeve with fastening tape straps for a secure fit.
