Under Armour Performance Boxerjock 6 inch Inseam Midnight Navy Men's Boxer Briefs

Engineered with HeatGear® fabric and a 4-way stretch construction, the Under Armour Performance Boxerjock delivers a second-skin fit that moves with you through every rep, sprint, and stretch. The ultra-light polyester-elastane blend wicks sweat away from the skin, keeping you cool and dry when training heats up.
