The new MET Trenta 3K Carbon is the most ventilated road helmet ever developed, engineered for the toughest races and refined in MET’s proprietary wind tunnel, the Tube. Already a winner at the Tour de France and the Giro d’Italia Women, the Trenta 3K Carbon represents the ultimate expression of a modern road helmet. The air has changed—and so has the standard.

The Trenta 3K Carbon has been tested in the Tube, MET's proprietary wind tunnel, using aero and thermal cell-equipped headforms capable of analyzing drag and temperature variations generated by airflow.

The helmet features the 3K Airframe, a carbon wing structure that eliminates EPS from the internal frame. The result is a continuous internal air channel, uninterrupted from the front intake to the rear exhaust, ensuring consistent airflow at both high and low speeds.

The new construction achieves a 40% improvement in the Virginia Tech test — the world’s most recognized independent safety rating protocol — earning 5 stars and one of the best scores ever recorded.

The new Trenta 3K Carbon arrives at exactly the right moment, made for an era where racing demands more — more speed, more control, more protection.
