Bring the speed in the On Race Tights. These running shorts are primed for race day. They are Swiss-engineered with a cross-over design that adapts to the shape of your body to personalize the fit and promotes your natural running motion, so you can kick it into high gear. Runners in our On Spring Apparel review loved the silky smooth materials and how these shorts stay in place without riding up, but did note that they ran a little larger. These shorts feature sweat-wicking materials and a laser-cut perforated waistband to keep you dry and comfortable all run long. Plus, there is a very small inside pocket to store a key or good luck charm on race day. The On Race Tights give you the lightweight performance you crave for high intensity workouts and race day finishes.
