Run, lunge, or stretch in these lined shorts with a classic fit and lots of storage space. They're made with lightweight, four-way stretch, and sweat-wicking Swift fabric and feature a Mesh fabric vent on the back. They're lined with OOM (Out of Mind) liner construction that fits like a short, not a brief. The OOM liner is made with quick-drying Mesh fabric, a built-in pouch to keep your boys feeling supported, and a phone pocket with cord exit. To make these shorts more versatile, we designed an envelope pocket at the centre back that holds your device securely without a zipper.SLIM FIT. PLEASE CONSIDER SIZING UP.
