This men's boxer briefs multipack is made from a high-quality X-Temp™ 4-way stretch mesh fabric that's designed to adapt to your body temperature. So as your body sweats, the smart technology wicks away moisture and reduces odor to keep you feeling comfortable all day long. Our experts also designed them with a Comfort Flex® waistband that helps your men's underwear flex and move with you. And their no-ride-up design stays securely in place, so you don't have to keep adjusting throughout the day. Plus, you can throw them right in the washer when they need a quick refresh. And our favorite feature part of all? These men's boxer underwear sets are available in multiple size options that won't ride up, so you can choose the one that works best for you.
