Go ahead, get sweaty. The Pro Boxer Brief was made to move. 

We've elevated this breathable, moisture-wicking wonder by adding Ionic+™ no stink technology; a permanent silver anti-odour system that kills stink before it starts, preventing the growth of odour-causing bacteria. Better still, it's built-in technology that won't wash out. This 6.5" style keeps your sweat wicked, your form tight and everything else fresh.
