Under Armour ® Performance Apparel was developed by athletes for athletes. With an understanding of an athlete's needs and the demands of competition, what began nearly a decade ago with a superior undershirt for equipment sports has evolved into six diverse gear lines to cover all seasons, climates and conditions. By employing only the finest microfiber fabrics, Under Armour ® has engineered the ultimate Moisture Transport System in garments that slide over your body like a second-skin to keep you cool, dry and light throughout the course of a game or workout. As the originator of the industry, Under Armour ® remains dedicated to new technology and is determined to enhance the performance of every athlete on every level. Lighter. Faster. Longer. Better. The advantage is undeniable.
