The unique HyperKewl Cooling fabric absorbs, stores and releases water within the multi-layered patented material. Water is released through evaporation, energy is consumed, and a chill effect is created. The HyperKewl Cooling fabric actually cools the body exactly the same way the body cools itself through evaporation of sweat.

When the vests are worn over a shirt or uniform – undergarments will remain dry due to the waterproof lining. The item will start cooling immediately and will stay cool for 5-10 hours depending on airflow and relative humidity.

The Technology:

HyperKewl™ (CE-certified) products utilize a unique chemistry to achieve rapid absorption and stable water storage. The chemical formulation also creates enhanced evaporation. Users can expect the evaporative cooling fabric to provide temperatures that are 10-15 degrees Fahrenheit cooler than the ambient temperature, depending on airflow. Please note that high humidity (90%) will diminish the fabric’s ability to evaporate water and therefore provide cooling.
