Light up your pre-dawn or post-sunset runs in this lightweight, high-visibility men's running short. The short includes boxer-brief liner plus plenty of pockets. 3M™ Scotchlite™ Carbon Black Stretch reflectivity placed in critical motion zones helps drivers recognize you as a runner in motion. Carry the essentials in the zippered pocket at center back — big enough for a phone — or in the pocket on the leg of the liner. Enjoy added comfort thanks to the sweat-wicking mesh boxer brief liner.
