Under Armour LAUNCH 7'' SHORT’s for men are made of an ultralight, stretchy fabric for optimal mobility. The inner mesh lining helps wick perspiration and improves breathability. They have side mesh panels for enhanced breathability. The 4-way stretch technology allows material elasticity in all directions. The material wicks sweat away from the body and dries super fast.
