Keep cool in hot, humid conditions and preventheat stress, strokeor heat exhaustion with these patented科技niche HyperKewl™ Plusevaporative cooling skull caps. HyperKewl™ "super-charges" the body's natural cooling process as the unique evaporative cooling fabric absorbs and slowly releases water through evaporation. This cooling technology requires some airflow to provide temperatures that are 15-20 degress (F) cooler than the ambient temperature.

Simply soak in water for 1-2 minutes for 5-10 hours of effective cooling during competition or strenuous activity. Comfortable, quilted 100% cotton outer with HyperKewl™ fabric inner water repellent nylon liner. Adjusts with convenient strap clincher.
