Mission Workshop has got a new short sleeve oxford for the summer that uses a fabric technology that fights sweat. The technology is called 37.5 and it not only does it keep your perspiration in check, but it also helps reduce the creation of liquid sweat. Alongside moisture management, it also keeps odor in control and it doesn't need any chemical finished to accomplish any of these features and will never wash out.
