As invisible and ultralight as the air for which it was named, SISU Aero is the high-tech mouthguard that started it all.
Designed to allow athletes to easily talk, breathe, and drink during game time. Using revolutionary Diffusix technology, SISU mouthguards are 8 times tougher and 30-50% stronger than conventional mouthguards.
You'll be able to start each game with confidence knowing that no matter how hard you hit, your SISU is there to protect you.
In contrast to the large, clunky guards you've come to expect, every SISU is a super-slim thin. They're so small that you'll honestly forget you're even wearing a mouthguard!
