On Running Core Long-T

The On Core Long-T is a technical long-sleeve running top for male athletes, available in black and size XL. This performance apparel is designed for high-intensity training and endurance running in varying conditions. Made from a lightweight, moisture-wicking polyester blend, it actively regulates sweat to keep the wearer dry and comfortable. The material features a breathable mesh structure that promotes optimal air circulation and temperature regulation during strenuous activity. A key design feature is the seamless construction in areas with high freedom of movement, which minimizes friction and reduces the risk of skin irritation. The fit is athletic and close to the body, developed for freedom of movement without excess material. The collar and cuffs are designed with a comfortable, non-restrictive finish. Reflective details are integrated into the design to enhance visibility in low-light conditions and support safety during early morning or evening runs. The shirt is suitable for a wide temperature range and works effectively as a base layer in cooler weather or as a standalone top in milder climates. It is compatible with layering under jackets or vests. The fabric is treated to resist odor formation and maintain freshness during extended wear. Care instructions recommend machine washing at 30 degrees Celsius and avoiding fabric softeners to preserve the technical properties. The On Core Long-T embodies a focused approach to running apparel, prioritizing functional performance, durability, and practical comfort for demanding training sessions.
