Under Armour Perf Tech 3in
Put on the men's boxer briefs Under Armour Perf Tech 3in and stop worrying about what you have under your shorts for running or training. The pack includes three pairs in gray, so you have fresh boxer briefs ready every time you head out the door.
The boxer briefs are made from lightweight recycled polyester that quickly wicks away sweat. The addition of elastane gives them flexibility, allowing them to move with you. The 3-inch inseam stays in place, not rolling up during squats or lunges, and doesn’t get in the way under your shorts. You'll appreciate them at the gym, on a brisk ride in the park, or during an everyday outing. Under Armour was founded in 1996 by former football player Kevin Plank. He was looking for a shirt that wouldn’t soak up sweat under his jersey, and functional sportswear has remained the brand's foundation to this day.

Materials
