SISU Mouthguards in Stock

• SISU Aero Nextgen Mouthguard — SISU's flagship ultra-thin mouthguard — at just 1.6mm thick, the SISU Aero is significantly thinner than a standard boil-and-bite mouthguard — moulded at home in hot water to create a precise custom fit that holds in place without biting down — the thin profile allows normal breathing and speaking during play, making it a popular choice for Irish rugby and GAA players who find traditional mouthguards bulky and uncomfortable — remoldable up to 20 times if the fit needs adjustment

Why Choose a SISU Mouthguard?

• Ultra-thin profile — at 1.6mm, the SISU Aero is one of the thinnest certified mouthguards available — far less bulky than a standard boil-and-bite mouthguard — players can breathe, speak, and drink water without removing it
• Custom fit at home — moulded in hot water to the exact shape of your teeth — provides a more precise, secure fit than a standard boil-and-bite mouthguard without the cost of a dentist-fitted custom guard
• Remoldable — can be remoulded up to 20 times — useful for growing players whose teeth are still changing, or for players who want to adjust the fit
• Certified protection — despite its thin profile, the SISU Aero meets international mouthguard protection standards — suitable for rugby, GAA, hockey, and other contact sports
