The SISU Aero Mouthguard is the latest evolution in mouthguard engineering from the makers of SISU Guard. Simply put, it's 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 added protection and comfort.


The Aero is made from a high-tech thermoplastic material that is 30% stronger and has 8 times the tensile strength of conventional mouthguard materials. This means that no matter how intense things get during play, your SISU Aero has your back and your teeth.


The most unique feature of the SISU Aero is its ultra-thin and ultra-light design. At 1.6mm thick, the Aero is 50% thinner than your standard mouthguard. Combined with its quick, custom, remoldable fit, you'll completely forget there's anything funky and plastic in your mouth.
