Radians ST21B type R class 3 hi-viz T-shirt with Max-Dri moisture wicking mesh is made with an arid birds eye mesh allowing for maximum breathability, without compromising durability. The stripes are adhered by heat transfer rather than sewn-on, making the safety T-shirt wear much more like a regular T-shirt. The wicking properties improve hot weather comfort making it feel much cooler. The front pocket does not include reflective material to allow for corporate imprints. Color blocking at the bottom of the T-shirt.
