"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 9"" underwear stretches, recovers, and fits exactly how you want it to."
