Men's UA Base™ 2.0 Boxerjock® Boxer Briefs

what's it do?

Our best-selling Boxerjock® boxer briefs deserved a ColdGear® update for the bitter cold. We started with our UA Base™ performance thermal fabric. And these aren’t your grandpa's long underwear. We took the traditional thermal and rebuilt it to work for off-road athletes. The unique negative grid traps monster warmth without adding excess weight. When the temps are dropping around you, heat up your game with the UA Base™ 2.0 Boxerjock®.
