Designed for casual or workout wear, our Loose Fit UndergearTM shirts feature key design ingredients such as: saddle shoulder construction that allows 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 chaffing. UndergearTM is made out of Dri-X-treme? moisture-wicking, anti-microbial and quick drying fabric. Available in short sleeve and long sleeve crew necks. Generously sized. 100% polyester. Imported.
