A special neck wrap made of polyester and cotton, filled with polycrystals. When placed in clean water for up to 30 minutes, the crystals expand and produce an evaporative cooling system for the user when worn around the neck.
The Body Cooler lowers the body temperature by cooling the carotid arteries in the neck. The continuous moisture from the expanded crystals surrounding the warmth of the neck allows evaporation to take place. It is comfortable and hand-made from the finest materials.
