Under Armour was founded in 1996 by Kevin Plank to produce athletic clothing that keeps athletes cool, dry, and light. It initially targeted professional athletes and serious fitness enthusiasts with tight-fitting moisture-wicking shirts. Now, Under Armour produces a full line of performance apparel and footwear for various sports. It focuses on differentiating its products through special fabrics for hot, cold, or variable temperatures. Under Armour has grown significantly and sponsors many sports teams internationally through various retail channels and promotional efforts.
