The Performance Lab Split Shorts are cut from an 85gsm French-milled fabric composed of 88% polyester and 12% elastane, delivering a lightweight, stretchy foundation suited to high-intensity training and long-distance racing. The unlined 2-inch silhouette features built-in moisture-wicking and odor-control properties, while strategically placed thigh ventilation promotes airflow and heat management during sustained effort. Side slits extend the range of motion, and a secure rear pocket keeps essentials close without adding bulk.
