DESCRIPTION & What's included?

The MET Trenta was created to mark our 30th anniversary year. We wanted to develop a helmet for elite riders, a competitive edge for the best in the sport. The name, of course, is the Italian for ‘30’.

Originally developed by NACA, a precursor to NASA, the position of this inlet at the front of the helmet has a cooling effect.

Harnessing the power of the Venturi effect, the vent pushes out the warm air within the helmet through specially positioned exhausts.

This ensures constant airflow through the helmet, without catching the wind and creating drag. 


The back of a helmet has a huge impact on how well ventilated it is, with the exit of warm air from within a key priority.

The MET Trenta features a flat rear deflector inclined at 25°, which makes it possible to include two wide exhausts that optimise airflow when you’re on the drops and riding hard.



  • All-round belt offers 360° adjustment
  • 4 positions for vertical adjustment
  • 2 positions for occipital adjustment
  • Ponytail compatible
  • MET USB LED light compatible


Dedicated ports for securely docking sunglasses.


The tail of the helmet also has an aerodynamic purpose. 

It works in synergy with the NACA front vent and the rear deflector to effectively drive airflow.

It has a lower profile at the rear, which we developed thanks to specific wind-tunnel testing in the NEWTON laboratory of Milan.


We built the MET Trenta in such a way that only 30% of the head will be in contact with the helmet when you’re wearing it. 

This allows the other 70% to benefit from the optimised airflow passing through the internal cavity, keeping you cooler as you ride.
