ThermApparel UnderCool Cooling Vests work with ThermApparel’s Cooling Packs coming into contact with the body to absorb and pull heat away from your core which lowers and stabilizes your body temperature. The heat absorption lengthens the time it takes for your core to reach the point of overheating.
