The SISU Aero Mouthguard is a high-performance upgrade for athletes who want serious protection without the bulk. Engineered with NextGen thermoplastic, the Aero is 30% stronger and offers 8x greater tensile strength than standard mouthguard materials—giving you elite level impact resistance in a slim, low profile design.

At just 1.6 mm thick, it’s 50% thinner than traditional mouthguards, making it easier to talk, breathe, and hydrate without removing it. The custom, remoldable fit adapts to your bite for a secure seal and personalized comfort, while the ultra light feel makes it easy to forget you’re even wearing one.

Ideal for hockey, lacrosse, and other contact sports, the Aero combines advanced protection with unmatched convenience. It’s built to stay in place, absorb impact, and let you focus on your game—not your gear.

Minimal in size, maximum in strength—a mouthguard that protects like a tank and wears like air.
