So what is 37.5®? It is a fabric treatment technology that uses active particles from volcanic sand with billions of micropores, massively increasing the surface area of the material by up to 800%. When you're hot, the active particles use your body's energy to remove moisture and cool you down. This can result in better performance, increased efficiency and greater comfort.
