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. MORE PROTECTION The Aero is made from a high-tech thermoplastic material that is 30% 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 is its super-slim, ultralight design. At a lean 1.6 mm, the Aero is 50% 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.
