The Pro Seamless Crew was inspired by a pitcher's required range of motion on the mound, and applies that insight to any performance activity you may encounter. We target the upper body with this garment's saddle raglan shoulder, preventing chafing in high-movement touchpoints but also engineering ventilation in those same spots for maximum air flow where you feel the most heat. The discrete high-performance functionality in the Pro shirt comes from the warp-knit construction that works even harder for you -- and the environment -- without appearing overly technical.
