Young baseball players, this Descente undershirt is exactly what you need for maximum comfort and performance on the field! The 4-way stretch material moves with your body during throws, swings, and dives without restricting movement. Made from their Infinity Air Knit 2 fabric that's super lightweight while being amazing at sweat absorption and quick drying. The high neck design provides extra coverage and protection, while the special armpit construction reduces stress when you're lifting and turning your arms. The underarm fabric is engineered not to fray, which means less irritation and chafing during long games or practices. The back is specially sewn to avoid shoulder blades, giving you complete freedom of movement for those powerful throws. With a composition of 50% polyester and 50% composite fiber in the main body, and 100% polyester underarms, this shirt is built to handle the demands of serious baseball play. Whether you're pitching, catching, or playing the field, this undershirt keeps you dry, comfortable, and moving freely. Seriously, if your current undershirts feel restrictive or get soaked with sweat, this Descente option will completely change your game-day comfort level!
