Perform your best during a race or during your gentle training with the On Running running shorts.

These ultralight 5-inch shorts are made to test your speed limit. The shorts feature supportive inner shorts and a zip pocket at the back, making them perfect for road running, indoor workouts and more.

Optimal comfort: The stretch woven fabric feels smooth against the skin, while the supportive inner shorts keep you comfortable even over long distances. A perforated mesh back increases airflow, keeping your temperature regulated even during intense efforts.

Back zip pocket: Designed for (and by) runners who know exactly what they need, when they need it. Think of an integrated back pocket with zipper and a key loop to store essential items safely. Or the DWR material that repels rain. These shorts are the perfect companion for serious runners who appreciate style and functionality.
