SISU™ is a winner
Why SISU Guards?
Bravery, Tenacity, Endurance, Perseverance, Courage, when faced with great adversity. That's the meaning of the word SISU and the philosophy behind our mouth guards. SISU mouthguards, which were developed by doctors and scientists, are only 1.6 mm thin, yet are 30% stronger than the conventional guards. Our guards let you do what other guards can't—talk, drink and breathe.
