The No Fly Zone Defender Hat is constructed of nylon & polyester and features bug repellent properties of patented No Fly Zone technology. This style features a sun protective brim and chin cord offering ultimate protection from outdoor elements. No Fly Zone Technology No Fly Zone is a permethrin-based technology that may help prevent the spread of insect borne diseases by repelling insects. This technology is similar to the natural insect repellent found in certain chrysanthemum plants and works as a contact repellent affecting the insect's nervous system causing it to fly away before a bite can occur. No Fly Zone technology has proven to provide a safe, effective barrier against up to six different insects including mosquitoes, ticks, chiggers, flies, ants and midges. The technology can be applied to polyester, nylon, cotton, wool and aramids and is durable for up to 70 home launderings. HyperKewl PLUS Technology 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 10-15°F/6-8°C 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.
