The comfort-fit design of the DeMarini team shirt is built to be worn under your game jersey or as a workout shirt. These performance pieces are perfectly fitted, not too tight or baggy. Body-mapping mesh inserts provide breathability, and the body fabric stretches in all directions to allow a full range of motion. The antimicrobial protection inhibits bacterial growth, protecting against stains and odor, while the moisture management system wicks moisture away from the body to keep players dry and comfortable - 91pct polyester/9pct spandex.
