MET Trenta 3K Carbon Helmet - Black Matte, Small

The new MET Trenta 3K Carbon is the most ventilated road helmet ever, developed for the toughest races and refined inside the Tube, MET's proprietary wind tunnel. Already a winner at the Tour de France and the Giro d’Italia Women, the Trenta 3K Carbon is the ultimate expression of a modern road helmet. The air has changed, and so has the standard. 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 Trenta 3K Carbon arrives at exactly the right moment, made for an era where racing demands more — more speed, more control, more protection.
