The Leatt Coolit Vest employs the simple heat transfer principles of conduction and convection to accomplish cooling the rider. Hyperkewl fabric in the vest stores the water and uses a proprietary chemical formulation to control evaporation, resulting in 10-15°F vest temperatures cooler than ambient air according to Techniche International (the inventor). Leatt advertises a 15-20°F cooler feeling with the Hyperkewl fabric incorporated into the vest. The vest is worn directly against the skin allowing body heat to be transferred into the vest via conduction. The water in the vest evaporates over time via convection, providing a cooling sensation for the rider. Leatt claims the vest is capable of cooling for one to six hours depending on weather conditions.
