Under Armour Performance Mouthwear™

No one ever told you that your jaw could help you perform better.

No one ever told you that your jaw could help you perform better.

That's because no one knew. Hundreds of years ago, a few people were on to something. Ancient Greek athletes bit down on leather straps for an edge during competition; Viking and Roman warriors clamped down on leather bits for focus on the battlefield. They knew something about it worked, but the concept itself never evolved. Until now.

Under Armor Mouthguard

Under Armour Performance Mouthwear has been engineered to unlock your power and potential. It's all in you, but blocked by one of the human body's instinctive reflex systems: teeth-clenching. With safe, custom-built UA Performance Mouthwear, athletes in any sport - from football to golf to hockey - can capitalize on innovation that makes you stronger, faster, and better.

Whether you need protection during contact sports or you just want to improve your game, Under Armour Performance Mouthwear, with ArmourBite® Technology, gives every athlete an edge.

Jaw Dropping Performance

Powered by ArmourBite Mouthwear Technology

Increases Strength

With improved airflow and less stress from clenching, UA Performance Mouthwear has been proven to increase strength by an average of 17% with the UA Performance Mouthpiece and 12% with the UA Performance Mouthguard.

Increases Endurance

UA Performance Mouthwear enlarges airway openings, resulting in 25% less lactic acid build-up after 30 minutes of intense exercise.

Speeds Up Reaction Time

Athletes may respond faster when wearing UA Performance Mouthwear. Clinical trials show an improvement in responding to auditory cues and potential improvement in response to visual cues.

Reduces Impact

When the jaw suffers an impact, energy can be transmitted to the head, which can cause concussion. UA Performance Mouthguards have been shown to the G-Force impact of blows to the jaw by up to 20%.

Unclench Your Jaw And Unleash A Better Athlete

You are "hard-wired" to clench your jaw.

When you train and compete, your natural reaction is to clench your jaw. It's part of the "fight or flight" wiring of your brain. Your clenched jaw and teeth compress your temporomandibular joint (TMJ), triggering the release of excess amounts of performance-sapping hormones (like cortisol) that produce stress, fatigue, and distraction.

Under Armor Mouthguard

UA Performance Mouthwear helps the human body help itself by unlocking the power of the jaw. Patented ArmourBite Technology prevents your teeth from clenching and pivots your jaw forward to relieve pressure on the TMJ. Gone are the excess negative hormones and the energy-draining effects. Now the body can unleash its full potential. Independent studies conducted at some of the nation's top universities and research centers have proven the undeniable advantages of UA Performance Mouthwear.
