The MET Trenta 3K Carbon Mips® is a high performance road helmet designed with elite cyclists and worn to victory at  Le Tour de France and the monuments of Liège-Bastogne-Liège and Il Lombardia. Engineered to keep your head fresh and save you energy with every pedal stroke, the MET Trenta 3K Carbon Mips® is the most advanced road cycling helmet we have ever made, now upgraded with the addition of Mips AIR®, the lightest and most advanced rotational management system.

MET never compromise on safety performance, adding Mips AIR® we have integrated into the padding the lightest and most advanced rotational management system.
Mips AIR® was specifically developed and designed to be the lightest system possible to reduce rotational energies transferred to the head during specific angular impacts. Unlike traditional Mips cages, Mips AIR® is integrated into the padding of the Trenta 3k Carbon and enables 10-15mm of relative movement between the energy absorbing layer and the padding.


The construction of the MET Trenta 3K Carbon Mips® is the highest level on the market. Our R&D team have taken advantage of carbon fibre’s elastic modulus which allows us to reduce the density of the EPS foam by 20%, without affecting the capacity of the helmet to absorb energy. The result is a lightweight yet better-performing shell that sets a new standard for ventilated helmet design.


Originally developed by NACA, precursor to NASA, the position of an inlet at the front of the helmet harnesses the power of the Venturi effect, pushing out warm air within the helmet through specially positioned exhaust ports. This ensures constant airflow through the helmet, without 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 3K Carbon Mips® 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.


The low profile Kamm 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, and was developed through specific wind-tunnel testing in the NEWTON laboratory of Milan.


We built the MET Trenta 3K Carbon Mips® 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.
