Designed for casual or workout wear, our Loose Fit Undergear™ shirts feature key design elements such as saddle-shoulder construction that permit a greater range of motion, an underarm mesh panel that allows moisture to vent and evaporate easily, and flat-lock seams that reduce friction in order to prevent chafing. Undergear is made out of our moisture-wicking, antimicrobial and quick drying fabric. Available in short- and long-sleeve crew necks. Generously sized. 100% polyester. Imported.
