MET Rivale bike helmet (dark grey)

The MET Rivale presents itself as compact as possible, but still has many ventilation openings. With the NACA vent*, we harness the power of the Venturi effect, another marvel of Italian engineering, to ensure the most efficient airflow through the helmet. At 230g, the MET Rivale doesn't have to hide from the competition either, even though it is first and foremost an aero helmet.

NACA vent is a ventilation opening developed by NACA, a predecessor organisation to NASA, to provide optimal cooling.
