This cap, with a smooth front and stretch for comfort, wicks moisture and carries on a performance legacy.

It features a mid-profile and hook and loop closure, with a contrast Swoosh logo on the bill. Made of 5.6-ounce, 90/10 polyester/spandex. Note: Despite being labeled M/L, it's One Size Fits All.
