Our combination of specialized fabrics and fibers create an advanced water management system that we call HyperKewl. Our unique HyperKewl fabric absorbs, stores and releases water within the multi-layered structure. Water is “released” through evaporation, energy is consumed, and a chill effect is created. Our HyperKewl fabric actually cools the body exactly the same way the body cools itself through evaporation. We simply supercharge the natural cooling process.

How it Works
HyperKewl products utilize a unique polymer chemistry to achieve rapid absorption and stable water storage. Our chemical formulation also creates enhanced evaporation and longevity. Users can expect the HyperKewlTM evaporative cooling fabric to provide temperatures that are 15 - 20 degrees (F) cooler than the ambient temperature. The exact temperature difference will depend on humidity, exposure to airflow and other environmental conditions.

Please note: High humidity (90%+) will diminish the fabric’s ability to evaporate water and therefore will not provide cooling without significant airflow such as on a motorcycle.
Each garment comes with 2 hang tags and a care label that fully explains how best to use the product and care for the product.
