Under Armour Rush is the gear you wear when it counts - for your toughest workouts, your most important games, and your most intense workouts. The Rush Energy Training Shirt for men fits right in. The wide cut crew neck shirt lays the groundwork. The 4-way stretch fabric provides natural freedom of movement in all directions, wicks sweat and dries very quickly. Rush is an infrared technology that returns energy to your body so you can train harder and recover faster. The hem with side vents provides an optimal fit. A reflective logo completes the look.
