I've had several mouth guards but didn't use them during sports activities, because I couldn't talk and breathing. That's not a problem with my sisu. I wear it for sports and forget it's there.

Hands down the most amazing mouth guard I've had. After I finished molding it I walked around wearing it for an hour because I was so amazed how well I could talk and breathe and I hardly knew it was there! I'm excited to officially test it when the season starts.

My son actually keeps this in his mouth for the whole game!

My son is really tough on mouthguards. A friend recommended the SISU. Even my son has a tough time chewing on this one because it sits so securely in his mouth. The molding process was very easy to follow. I love that it is remoldable and so thin, but still has a solid dental guarantee. Would definitely buy this again in the future. This is an excellent product!

I really liked my dentist fitted mouth guard but after using the SISU mouth guard I could never go back. The durable, small, lightweight mouth guard is incredibly breathable and I can even speak clearly with it in. I strongly recommend the SISU mouth guard for any athlete.
