Under Armour Armourshield Mouth Guard has patented Bite Flex and ArmourPlate technologies provide impact protection for teeth, jaws and gums. Under Armour Bite Flex absorbs energy on impact while contoured EVA material ensures a comfortable fit. Under Armour's patented polymer shrinks for a secure, locked in fit so the mouth guard stays snugly in place for easier breathing. It also makes it easier to talk with the guard in place.
