SISU 2.4 Max Guard

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