Pro Sauna Shirt™ is designed to help you sweat more during training. Built with an upgraded 3-layer fabric system, it traps body heat to support heavier perspiration and higher workout intensity.
It feels like a normal performance t-shirt on the outside, but works as heat-trapping gear on the inside — helping your body work harder while allowing full freedom of movement.
