From sprint repeats on the track to long runs on the trail, the Ten Thousand Distance 5in Liner Short has us feeling our best. The insanely light construction feels like a whisper against our skin, yet the pockets still manage to hold our keys and phone tight to prevent bounce from pulling down our fit. Whether we're shuffling or opening our stride, the brief liner gives us the anti-chafe support we need, and the performance fibers and perforated panels ensure we don't get sweat-logged.
