Riders need to stay cool while riding. As your core temperature rises your body loses function and you can’t ride as well. The Coolit T-Shirt relies on the Hyperkewl material to absorb, store and release water over time. Worn next to the skin to, initially, keep you cool by the coolness of the water and later, by the evaporation process. Light, cool, inexpensive and effective. Now, go ride, even if it is hot.
