The HyperKewl Evaporative Ultra Sport Vest is as the name implies created for ‘ultra’ athletes. The vest is designed to provide cooling when you train and/or compete in hot temperatures, especially on long distances.
The purpose of HyperKewl Evaporative Ultra Sport Vest is to provide cooling over a long period. The cooling vest is activated by soaking it in water before use, after which the water is absorbed in a special material on the vest front and back. The water slowly evaporates and provides a cooling effect. This helps the vest stay cooler than the air temperature.
According to the manufacturer TechNiche International, the HyperKewl Evaporative Ultra Sport Vest will maintain a temperature that is between 6-12 degrees lower than the air temperature and will remain cool for between 4-10 hours.
The cooling vest can easily be “rehydrated” when the effect ends. Overall, there is no doubt that the HyperKewl Evaporative Ultra Sport Vest provides a cooling effect. The vest weighs about 1 kg when it is drenched – and is somewhat stodgy fit, however, the benefits of the cooling vest outweigh this. (read full review)
