CoolMax clothing is constructed from a special blend of fibers that are specially designed to be soft, breathable, and highly evaporative. The fabric pulls moisture away from the body and distributes it across the CoolMax fibers for quick evaporation, and the breathable nature of the garment allows air to circulate and keep the body cool. Needless to say, we believe that once you try the CoolMax shirt for yourself, you'll wonder why it took you so long to purchase! Comfortable, cool to the touch, lightweight, breathable, and easy to care for, the CoolMax shirt is a must-have if you race karts or cars!
