Under Armour's massive headquarters is a sports fan's dreamland - take a look inside

Working at Under Armour's Baltimore headquarters is a sports fan's dream.

When its 2,000-some employees - or as Under Armour calls them, "teammates" - aren't working, they can shoot hoops at the company's swanky basketball court or work out in its high-tech gym.

As it strives to become the world's top athletic brand, Under Armour is also expanding fast. Since the company's launch 20 years ago, it has opened offices on five continents and now has about 12,000 "teammates" globally. But its Baltimore home base is where it all started.

We recently got a tour of the massive campus. Check it out.
