NO ODOR- ALL DAY, EVERY DAY Go ahead, get sweaty. The PRO XT2® Boxer Brief was made to move: we've elevated the breathable, moisture wicking wonder that is the Pro by adding XT2® NO STINK Technology, a permanent silver anti-odor technology that kills stink before it starts by preventing the growth of odour-causing bacteria and won’t wash out. This 6.5 inch style keeps your sweat wicked, your form tight and your boys fresh. Model: M121035
