The Under Armour Men's Vanish Energy Short Sleeve Tee is a high-performance athletic t-shirt engineered for training, workouts, and active use. Designed with a loose, fuller cut for complete comfort and unrestricted movement, this tee is built to handle the most demanding sessions without weighing you down.

Built with UA RUSH™ infrared technology, the fabric reflects your body's own energy back to help you work harder and recover smarter. The 90% polyester/10% elastane construction provides 4-way stretch that moves with you in every direction, while moisture-wicking technology pulls sweat away from the skin. The material dries rapidly so the shirt stays light no matter how hard you push. Odor control technology keeps you fresh throughout your workout, and a side-vent hem adds extra ventilation and freedom of movement.

Powered by CELLIANT®, the shirt supports performance at the cellular level. Available in Regular and Tall lengths across a wide range of colors and sizes (XS–4XL). Machine wash cold inside out with like colors; tumble dry low. Do not use fabric softeners, bleach, or dry cleaning.
