The new OS2O Women's Long-Sleeve Trail Running Shirt redefines lightweight protection and technical comfort with a design specifically tailored to the female anatomy. Designed for high-intensity mountain training and racing, especially during transitional seasons (spring and autumn), it offers an ergonomic fit, strategic breathability, and full freedom of movement for peak performance on the trail.

It is primarily made with Cool2Dry®, a stretchy technical fabric that delivers an ultra-soft feel against the skin, excellent elasticity, and quick-drying properties—ideal for variable or mild climates. The side panels, underarms, and inner sleeves feature ultra-light technical mesh, strategically placed to enhance ventilation in key sweat zones and maintain freshness even during extended efforts.

The long sleeves provide an extra layer of protection against brush, cool wind, or sun exposure—without compromising lightness or comfort.

A versatile, technical garment for mountain runners who demand uncompromising performance, effective thermoregulation, and added protection during mid-season conditions.
