Game-changing performance at a new lower price!

Brought to you by the brand that makes you better, the ArmourBite® Mouthguard is your new game-time essential. When you compete, your natural response is to clench your jaw and grit your teeth. But all that gnashing triggers the release of cortisol?a performance-sapping hormone that causes excess fatigue, stress, and loss of concentration. Not the best formula for success. But you can get your head (and jaw) back in the game with the ArmourBite® Mouthguard. It not only protects you from earth-shaking hits, it also reduces those nasty clenching side effects by pivoting your jaw to the optimal positioning with its patented ArmourBite® Power Wedges?. The result is a marked increase in strength, endurance, and reaction time. So unlock your power and unleash a better athlete with this game-changing mouthguard from Under Armour®.
