The Volcanxx shirt is made with temperature control fabric so it helps keep you at your core, comfortable temperature. This shirt is designed so that you can wear for athletic activities and also for everyday. The volcanic sand particles embedded in our fabric reacts to the infrared heat signals coming from your body to either disperse heat when you start to overheat or reflect heat when you are cold.
If you are an athlete you need that energy for performance. When Volcanxx fabric was lab tested against other wicking fabrics it gave athletes 28% more performance because it helped keep their core temperature lower for longer.
