Radians ST31 Cooling T-shirts feature Max-Dri moisture-wicking polyester, 40-plus UPF protection from the sun’s harmful rays and RADCOOL technology that self-activates when perspiration is present. This technology moves moisture away from the skin and circulates it through the fabric to keep workers cooler for longer. Available as a short- or long-sleeve T-shirt, the ST31 is designed with a mesh side-seam insert for extra breathability and segmented reflective tape. This transferred tape provides extra visibility in low-light conditions, improves breathability, and offers improved flexibility and mobility.
