Under Armour is an American sports clothing and accessories company. The company is a supplier of a wide range of sportswear and casual apparel mainly focusing on hi-tech sportswear for professional athletes. Under Armour began offering footwear in 2006.

The company was founded in 1996 by Kevin Plank, a 23-year old former University of Maryland special teams captain for the university American football team. Plank began the business from his grandmother's basement in Washington, D.C.

Plank, who got tired of having to change out of the sweat-soaked T-shirts he wore under his jersey, noticed that his compression shorts stayed dry, which inspired him to make a T-shirt using moisture-wicking fabric for athletic performance. Major competing brands including Nike, Adidas and Reebok soon followed in Plank's footsteps with their own version of Under Armour's moisture-wicking apparel.
