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.
Due to hygiene reasons mouthguards cannot be returned once they have been opened

I followed the instructions and could re-mould 9 times until getting the perfect fit, now it's ok and I barely notice I am wearing it.
