The MET Trenta was developed by MET for the 30th anniversary year. MET wanted to build a helmet for professional riders, a competitive advantage for the best of sport. The name is Italian, of course, and means 30. Optimised for use in the peloton, the tubular rear and internal ventilation channels of the MET Trenta provide 7% less drag than a traditional design and thus best performance for group rides. The NACA air vents and rear deflectors provide sophisticated airflow control inside the helmet, efficiently cooling your head without slowing you down. Especially since only 30% of the helmet lies on the head temperature control at the highest level.
