Special fabrics wick away perspiration, control stink, and increase range of motion, so workers remain comfortable all day, in any climate. 50+ UPF protection, crack-covering, dignity-saving, long tail cut and reflective accents add to the built-in bevy of bonuses that help the Mid Layer Series do you right. Constructed using advanced materials and designed with occupational athletes in mind. That means special stretch fabrics, raglan sleeves, and flat seams for improved range of motion. It also means technical yarns for moisture management and strong defense against vile, evil odor causing bacteria.
