Here's the secret athletes don't know about @Under Armour. They spent over seven years inventing a fabric that’s so breathable, it dries three times faster than spandex, keeping you cooler and drier no matter how hard you push. But that's not even the craziest part. The four way stretch on this fabric will actually move with you, giving you full range of motion to perform at your best And unlike spandex, this won't lose its compression over time, meaning you'll be at peak performance from day on
