As invisible and ultralight as the air for which it was named, SISU Aero is a 1.6 mm high-tech mouth guard. Designed for athletes who prefer to easily talk, breathe and drink during game time (otherwise known as: all athletes), the Aero is revolutionizing mouth guards one mouth at a time.

Why we love it…
