The HyperKewl™ evaporative cooling material is a unique fabric that absorbs and slowly releases water through evaporation. We look at this process as "super-charging" the bodies natural cooling process, thereby protecting the wearer against heat stress. While other technologies are effective for pre and post cooling while you compete, HyperKewl™ works to cool you during the competition or strenuous activity. Simply soak in water for 1-2 minutes, gently squeeze out excess water and enjoy the cooling effect for 5-10 hours. Simple, fast and easy to use!
