The CoolGrid™ Distance Singlet is engineered for long-distance running, featuring an open-mesh CoolGrid™ construction that promotes airflow and reduces heat buildup during sustained effort. The integrated Flopack™ system offers on-board storage for essentials without the need for a separate vest or pack, keeping your kit streamlined on training runs and race day. Designed with a performance fit, the singlet moves with the body and minimizes chafe over extended distances.
