Supercharge your body’s natural cooling system. At Leatt they take pride in your safety products and as riders and racers ourselves, we also know there is a need for some performance enhancing products. The Coolit vests and Coolit tees are Leatt's first combination performance enhancing/safety products. Riders need to stay cool while riding. As your core temperature rises, physical and mental performance suffers and you’re not able to perform at your peak. This rising core temperature is also dangerous and can result in heat stroke that may be fatal in extreme circumstances. The Leatt Coolit Vest relies on Hyperkewl, a technologically advanced material invented by Techniche International. Worn next to the skin, Hyperkewl initially keeps you cool with its absorbed water and continues to keep you cool later via the evaporation process. Light, cool and effective. The stretchable panels are made of moisture wicking fabric to further enhance the Coolit’s evaporation feature. Both the vest version and the tee version are light, cool, inexpensive, and effective. The tee version adds critical cooling to the blood supply running up your arm inside the bicep area. Beat the heat and ride faster and safer.
