Under Armour was founded in 1996 by Kevin Plank, a then 23-year old former special teams captain of the University of Maryland football team. Plank initially began the business from his grandmother's basement in Washington, D.C. In May 2008, Under Armour also opened a larger 6,000-square-foot (560 m2) store at Westfield Fox Valley in Aurora, Illinois. Under Armour has since opened several specialty stores and factory outlet locations in 34 states. Under Armour recently opened their first store outside of North America.

When success is 100% perspiration

Empowering athletes everywhere, Under Armour delivers the most innovative sports clothing, athletic shoes and accessories. Under Armour's big step up! The story of Under Armour's origins is a classic entrepreneurial tale: Plank was a walk-on special-teams football player at the University of Maryland in 1995 when, fed up with the sweat-soaked T-shirt he'd peel off after practice, he had the idea for a tight, polyester-blend shirt that wicks away moisture while keeping muscles cool.
