Designed for dedicated runners and athletes, the Under Armour Men's HG Armour 2. 0 Comp Short Brief provides greater support than what you'd experience with traditional boxer briefs. This compressive brief clings tight to your body, yet it still promotes full range of motion with its four-way stretch paired with a stretch-mesh gusset. HeatGear fabric wicks perspiration to aide in the body's evaporative cooling process, so you're not a hot, sweaty mess after exercise. It's finished with an anti-odor treatment for lasting freshness, regardless if you've been sweating profusely while pushing your physical limits.
