The Dutch soccer team uses during the enormous heat in Fortaleza special designed cooling vests. In the match against Mexico the soccer players wore their vests during the warm-up and halftime and controlled their body temperature in that way.
The Dutch Soccer Union has the cooling vests in stock for a while and uses them in circumstances like last Sunday, where the temperature rises till 39 degrees Celsius. The vests are being used for pre- and post-cooling of the body.
The cooling vests are continuous 14 degrees Celcius according to the manufacturer TechNiche Europe, which is 6 to 16 degrees cooler then the ambient temperature. This provides an optimal thermal comfort and therefore higher performance and faster recovery of the soccer player.
