COMFORTEMP products contain millions of microspheres which are preset to a temperature appropriate for the product.

When the body temperature exceeds the preset temperature, the microspheres absorb the excess heat creating a cooling sensation.[ Fig.1 ]

When the body temperature drops below the preset temperature, the microspheres release stored heat to keep the body warm at cooler temperatures. (Fig.2)

Your body heat and the ambient temperature continually recharge and recycle the microspheres to help keep you balanced and comfortable.

"COMFORTEMP. Stay cooler when it's hot and warmer when it's cold."
