No football coach in his right mind would recommend that student-athletes use helmets or shoulder pads from the 1950s. But that is when bulky EVA-based mouthguards – the same material still used to make most mouthguards today – made their entrance into the game of football. A mouthguard isn’t just a piece of equipment that makes a player game-eligible. Its first job is to protect the athlete’s teeth and keep that athlete safe. SISU mouthguards do that job better than any other mouthguard available using the latest in materials science.
