The Pro Seamless Long-Sleeve applies our centuries-long insight of athletes' movements to create a garment engineered for any high-intensity activity you may encounter. We target the upper body with a saddle raglan shoulder, preventing chafing in high-movement touchpoints, and further deliver seamless ventilation 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.
