SISU Mouthguard offers unparalleled quality and functionality, made of incompressible thermopolymer, is only 1.6 mm thick and designed to withstand impact. Powered by Diffusix™ technology, the SISU mouthguard deflects the force of the impact. Designed with the athlete’s needs in mind, its unique features focus on protection and comfort.

Upon impact, the perforated surface of the guard oscillates and forces are transferred from the teeth to a scientifically designed fragile area where the forces are absorbed into the incompressible surface of the guard.

Why Choose SISU Mouthguard

The Advantages of SISU Mouthguard


Using revolutionary Diffusix™ technology, SISU mouth guards square measure eight times more durable and 30-50% stronger than standard mouthguards. You’ll be able to begin every game confidently knowing that regardless of however laborious you hit, your SISU is there to safeguard you.


A mouthguard should not be something you dread wearing because it is uncomfortable. Unlike other large, bulky mouth guards, each of SISU’s mouth guards are 1.6-2.4 mm ultra-thin. They are so small that you’ll even forget you’re wearing a mouthguard!


SISU offers a comfortable custom fit so you can keep your mouthguard in your mouth throughout a race or training session without having to worry about it falling out. You simply don’t need to take your mouthguard off as often to talk, breathe or drink. And that means less bacteria transferring from your dirty, sweaty hands to your SISU pads.


In addition to being custom fit, each SISU mouth guard can be reshaped to ensure the best possible fit and maintain maximum comfort and protection. Simply place your SISU mouthguard back into hot water and it will be soft and flexible and ready to be reshaped.


The mouthguard keeps you focused, it makes your mouth free at all times of the game. When you wear your SISU, talking, breathing and drinking are largely unimpeded, so you can focus on what’s important: concentrating on the race.
