We construct our MicroTek Shirt using the same cutting-edge fabric found in our TekCheck styles featuring four-way mechanical stretch but in a heathered pattern. The perfect unsolid solid. Jam-packed with the features you've come to expect, you'll find a vented back panel with mesh lining, vertical venting at the chest, flat chest pockets, performance fabric with UPF 30+ protection, and a tagless collar. Fast drying, virtually wrinkle-free, with a full range of motion - this shirt will not disappoint
