Designed for whatever personal best or finish line you're pursuing, this stretchy running short delivers mobility and performance in an exceptionally lightweight design.

Stretchy, light and mobile, these shorts will keep you on pace during every trail run, uphill sufferfest, training session or race day. Lightweight fabric with ample stretch delivers range of motion and all-workout comfort no matter how tough or sweaty the session. A barely-there liner provides support and moisture wicking while the elastic waist and drawcord customize the fit. A hidden stash pocket in the liner stows small essentials when it’s time to transition from run to recovery.
