This multi-pack of men's boxer briefs is made with high-quality X-Temp™ 4-way stretch mesh fabric designed to adapt to your body temperature. So when your body sweats, Smart technology wicks moisture away and reduces odor, keeping you comfortable throughout the day. Our experts also designed the Comfort Flex® waistband to help your men's underwear flex and move with you. And their non-retractable design holds them securely in place, so you don't have to keep adjusting them throughout the day. Plus, you can toss it in the washing machine when you need a quick refresh. Our favorite feature of all? This men's boxer briefs set comes in a variety of size options and won't push up, so you can choose the size that works best for you.
