SISU NextGen is the most powerful mouthguard our scientists have ever built. With its unmatched quality and functionality, SISU NextGen was designed with the athlete in mind. Made from non-compressible thermo-polymer SISU NextGen is engineered to withstand even more impact. Still astonishingly 1.6 mm thin, SISU NextGen delivers even more protection with its scientifically re-designed perforation pattern. Custom fit, remoldable SISU NextGen features a wider bite pad, rounded edges and improved moldability to empower athletes to talk normally, breathe naturally and stay hydrated during the game. WITNESS EVOLUTION SISU NextGen is the latest evolution in mouthguard engineering by the makers of SISU Guard. Simply put, it is the most powerful mouthguard we've ever built. With its unmatched quality and functionality, SISU NextGen was designed with the athlete in mind, and its unique new features are hyper focused on additional protection and comfort. TRUSTED PROTECTION When you're sending your child out onto the field, court or ice rink for their first big game, you want to make sure they're as safe as can be. That's why our Junior guard is designed with the same tooth-protecting technology imbedded in every SISU. With 30% more protection than conventional youth mouthguards, you can rest assured your child's tooth safety is in excellent care. A SANITARY SOLUTION We know that every kid's favorite part of wearing a mouthguard is taking it out, rubbing their grubby paws through layers of sweat and mud, then reinserting their mouthguard now covered in batches of new germs. NOT ANYMORE WITH SISU JUNIOR! At 1.6 mm thin, our Junior mouthguard is so small and comfortable that kids don't feel the constant need to take it out, making for a cleaner mouthguard and a ier kid. THE SCIENCE OF SISU In our labs, we have put each mouthguard through strenuous testing to see how it performs in relation to its competitors. SISU Guards are made from unique medical grade thermo-polymer, which is, remarkably enough, free of harmful s. SISU material is non-compressible, which enables SISU Guards to outperform the competition in tensile strength tests. The tensile strength of our SISU material is consistently at least 30% higher than that of conventional EVA (a material most other mouthguards are made of). In reality, our material performs even better, due to the built-in Diffusix Technology, better protecting your teeth from damage. Learn more about the Science of SISU at sisuguard.com/the-science-of-sisu/ ENGINEERING Powered by our patented Diffusix Technology and engineered to withstand even more impact, SISU NextGen delivers even more protection with its scientifically re-designed perforation pattern. Based on suspension bridge technology, the main function of the perforations is to redirect the forces of impact. On impact, perforations oscillate and send the forces into our scientifically engineered Crumple Zones - the reinforced points of the guard that don't cave in under pressure. Here, the force of impact is redirected away from teeth and absorbed into the non-compressible surface of the guard. This unique design empowers SISU NextGen to protect you from even the toughest hits. COMFORT Custom fit, remoldable SISU NextGen features a wider bite pad, rounded edges and improved moldability. Rounded, bevelled edges soften the point of contact between the guard and the mouth, and improvements in the perforation alignment enable maximum dissipation of force transmitted from the point of impact. Superior protection is not the only function of the perforations. They also allow for flexibility to create an custom fit, so unique to the player's mouth that the guard remains in the mouth during the entire game or practice. Additionally, perforations allow for natural flow of air and saliva to empower athletes to talk normally, breathe naturally and stay hydrated during the game.
