SISU Mouth Guard
FREE SHIPPING ON ALL US ORDERS

SISU® is made from a non-compressible, perforated material and doesn't cave in under impact like conventional mouthguards. Using our one-of-a-kind Diffusix™ technology, the impact force is distributed over larger areas, which means less risk of dental injury during competition.

“the perforations in the SISU mouthguard act similar to the trusses on a bridge, allowing the structure to flex when an impact occurs.”
Johannes Schwank, Ph.D

Material Impact Dispersion

DIFFUSIX™ absorbs the diffuses impact throughout the entire mouthguard.

Conventional mouthguards are made from a material that's too soft to fully protect your teeth from harm.

SISU guards are made from a material that absorbs and diffuses impact throughout the entire mouthguard, meaning that much less impact force is transferred your teeth.

Diffusix™ technology works with unique impact-absorbing perforations and special "crumple zones" which direct the impact forces away from your teeth. When a SISU mouthguard is properly fitted, these energy-absorbing zones direct forces away from your teeth, reducing the risk of dental injury.

But why the perforations?

There are several reasons why the perforations are important:
  • They help strengthen the material by oscillating under impact, similar to how support systems function for a bridge.
  • They help you best fit your SISU because they allow for air to freely flow through the guard. This gives you a very snug fit, allowing you to clearly communicate with teammates and easily breathe while wearing your guard.
  • They improve the fitting process by allowing airflow through the material.
  • They enable you to freely drink water and stay hydrated during gameplay, and also experience less drooling!
