The Gorgonz Performance Work Hat is designed to keep your head comfortable throughout the year. The inner layer of DuPont Coolmax fabric pulls sweat away from your head, wetting the middle layer Hydroweave fabric, which then uses the heat of the sun to cause evaporation that further pulls away the heat. When dry, the Hydroweave has insulating performance that traps heat to keep your head warm. To keep your head drier than the standard hat, the Performance Work Hat has a water-resistant outer layer.
