A simple but highly effective body cooling product that works by evaporation. Immersion in clean water for approximately 15-25 mins allows poly-crystals to absorb and retain a large volume of water. When worn, the retained water evaporates and draws away body heat creating a cooling effect. Cooling effect increased by refrigeration. Great in hot conditions.
