SISU NextGen is the most powerful moldable 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, the SISU Aero mouthguard is engineered to withstand even more impact. Still astonishingly 1.6 mm thin, SISU NextGen Aero mouthguard 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.
Made in the USA FDA Approved BPA, Latex, PVC, Phthalate free. All Sports Size Medium is for athletes 5 feet tall to 6 feet tall (for average size mouths)
WITNESS EVOLUTION: SISU NextGen is the latest evolution in moldable 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, the SISU NextGen Aero mouthguard was designed with the athlete in mind, and its unique new features are hyper focused on additional protection and comfort.
MORE PROTECTION: The SISU Aero mouthguard is made from a high-tech thermoplastic material that is 30 percent stronger and has 8x greater tensile strength than conventional mouthguard materials. This means that no matter how intense things get during game time, your SISU Aero has your back and your teeth.
WAY LESS MOUTHGUARD: The most unique feature of the SISU Aero mouthguard is its super-slim, ultralight design. At a lean 1.6mm, the Aero is 50 percent thinner than your standard mouthguard. Combined with its quick, custom and remoldable fit, you'll entirely forget there's something awesome and plastic inside your mouth.
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 chemicals. 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 percent 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.
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 Aero mouthguard 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 intimate 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.

Okay
Kids wear them. Took a while to form and get the hang of. I guess they say it is more comfortable than the typical bulky mouthguard

Definitely not clunky
My boys really liked the lean, tight fit of this mouthguard. Easier to communicate to teammates. However, my goalie lost his pretty quickly since there wasn''t a method to attach it to his helmet.

SISU is GREAT!
Excellent! Easy to use. This is the 2nd SISU mouthguard I purchased for my daughter for roller derby. She needed a bigger size since she got braces. Even with the braces, it was easy to mold. Thin and fun colors. I definitely recommend! Oh, and Sportstop had super fast shipping. Thank you!

Good mouthgaurd , not bulky
Was looking forward to the “flat” mouthgaurd but it was very difficult for me to get it fitted to my teeth. Allows you to speak and drink. Very convenient for me because I’m a lacrosse goalie and I feel like I just need a mouth guard to get past the refs
