ADVANCED TECHNOLOGY The SISU Aero Mouthguard is the latest evolution in mouthguard engineering by the makers of SISU Guard. Simply put, it is the most powerful mouthguard they'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.
