The On Race Singlet is a men’s performance racerback built for race day, speed sessions and warm-weather running. Developed with On athletes, it combines perforated fabric across the front with a pleated plissé back to increase airflow while reducing contact against the skin. The main fabric is 83% polyester and 17% elastane, providing stretch without turning the top into a loose training tee.
Bonded seams around the armholes and neckline aim to reduce rubbing, while the lightweight close fit keeps excess fabric out of the way at faster paces. A reflective chest logo adds a small visibility detail, though this is not a substitute for dedicated lighting in low-light conditions. On describes the sizing as true to size.
This is a streamlined racing top rather than an all-purpose layer: the open racerback, airy construction and close cut are best suited to hot sessions and competition. Check local availability and colour-specific sizing before ordering because the model is listed as last season. The US$60 guide is On’s current US sale price, reduced from US$120 and checked 23 October 2026.
