The Dry Cooling Vest cools your body during hot summer days through the evaporation of water. The heat radiating from both the body and the surrounding air makes the water inside the vest vaporize. It causes the surface of your skin to cool down before you start to sweat. Thanks to the built-in cooling water reservoir, the Dry Cooling Vest will feel dry on your skin, whereas conventional vests need to be worn wet. By cooling the vascular system, the chance of suffering thermal stress is drastically reduced. This, in combination with the long usage time, makes the Dry Cooling Vest ideal for commuting, travelling and touring by motorcycle.
