High Quality Content by WIKIPEDIA articles! Under Armour, NYSE: UA, is a US clothing company best known for its introduction of form-fitting, moisture-wicking apparel designed to be worn under sportswear. Founder Kevin Plank was an American football player with the University of Maryland who got tired of having to change out of the sweat-soaked T-shirts he wore under his jersey, so he made a tee shirt using moisture-wicking fabric for athletic performance and founded the company in 1996. The company is a supplier of a much wider range of sportswear and casual apparel. Under Armour began offering footwear in 2006, and continues to expand its offerings.
