HyperKewl PLUS is a fabric that utilizes a rapid absorption, stable water storage, and enhanced evaporation to keep the wearer cool! This technology works best in an environment with high airflow, and low humidity.



HyperKewl PLUS fabric absorbs and then slowly releases water through evaporation. When the water evaporates, energy is consumed, and a cooling effect is created. We look at this as supercharging the body’s natural cooling process.



The more airflow, the more cooling power! Wind, fans, rapid movement (like on a horse, or a bike, or other open air vehicle), will maximize the cooling effect. HyperKewl PLUS can provide cooling of 10-15F/6-8C cooler than the ambient temperature, depending on the amount of air flow. The lower the humidity, the more easily the stored water will evaporate, and the more effective the HyperKewl PLUS fabric will cool.
