MET Trenta 3K Carbon MIPS Road Helmet

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.
