How does evaporative cooling work?

These garments harness the COOLING ENERGY that is produced when water naturally changes from liquid to gas (evaporation). Our Polymer Embedded Fabric is sewn into each garment lining and functions as a powerful liquid management system. Our Evaporative Cooling Apparel is activated by simply submersing it in water for 1 to 3 minutes, or until it reaches the desired level of hydration. Gently wring out excess water and its ready to wear. Once activated, the garments will provide hours of cooling relief and are an effective way to combat Heat Stress.
