Affordable enough for everyday wear, our Tight Fit Undergear shirts are designed to be worn under body armor and to provide support for a long workday. Key design features of this shirt are 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. Undergear is made out of Dri-X-treme® moisture-wicking, anti-microbial and quick drying fabric. Available in short sleeve and long sleeve crew necks and short sleeve v-necks. 80% polyester, 20% spandex fabric. Imported.
