SISU Mouthguards are known for their unmatched protection, comfort, cleanliness, and
remoldability. Though it might not seem possible, we made an even better mouthguard! SISU
3D improves on previous SISU models, and adds a number of new features: Pre-formed guard
for an effortless, fast, fit and go shape, and variable material thickness to put protection
where it is needed, and comfort where it is desired.
