A patented mouthpiece that increases airflow, strength, stamina & focus.
WHAT’S IT DO? The ArmourBite® Mouthpiece with patented ArmourBite® Power Wedges™ pivots your jaw forward when you run, lift, train. Why? To reduce your body's production of performance-sapping cortisol, while also maximizing air intake to increase your endurance and improve your strength, speed, and reaction time. UA's patented T-Bar Grip Fit System custom-fits the mouthpiece only on your lower teeth, which allows you to speak freely while it's in. Power, performance, and another game-changing innovation from Under Armour®.
