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

At its core is the 3K Airframe — a carbon wing structure that eliminates EPS from the internal frame, creating a continuous, uninterrupted air channel from front intake to rear exhaust. The result is consistent airflow at both high and low speeds, a 40% improvement in Virginia Tech safety testing, and a 5-Star rating with one of the best scores ever recorded.
