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.
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.
