Not your ordinary underwear—the Boxerjock® 9in boxer briefs are built for all-day athletes.


WHAT'S IT DO? When UA introduced The Original Boxerjock® boxer briefs, all other men's underwear was soon rendered obsolete. This underwear is built from UA’s smooth, sleek HeatGear® fabric for the best performance. The signature Moisture Transport System keeps you cool, the 4-way stretch keeps you moving, and the anti-odor technology keeps you fresh. Forget your old boxer briefs that bunch up, wear out, or lose shape. The Original Boxerjock® 9in underwear stretches, recovers, and fits exactly how you want it to.
