On Running Core Long-T

The On Core Long-T for men in black/black in size L is a technical running top designed for performance-oriented athletes. This long-sleeve shirt impresses with On's signature lightweight construction and targeted ventilation zones for optimal temperature regulation during high-intensity training. The fabric composition, typically a blend of polyester and elastane, offers moisture-wicking properties to keep the wearer dry and four-way stretch for unrestricted freedom of movement. The ergonomic cut follows athletic contours with flat seams to minimize chafing during long runs. Reflective elements enhance visibility in low-light conditions, supporting safety during early morning or evening training sessions. The shirt maintains a professional aesthetic suitable for both training environments and casual wear, with the On logo discreetly integrated into the design. Care instructions recommend machine washing at 30°C with similar colors to preserve fabric integrity and performance features over time. This model is a successor to previous On running tops and incorporates updated fabric technology and fit adjustments based on athlete feedback. The garment is designed to complement On's running ecosystem and pairs well with their shorts and tights for coordinated training outfits. Available in size L with a chest measurement of approximately 102-107 cm and a length of about 73 cm from shoulder to hem, specific measurements may vary slightly between production batches. The minimal black color scheme ensures versatility for various running conditions and personal style preferences.
