POC Procen Hydrogen White Size:M each of which can beA precise shape manages residual air travelling over and around the helmet, particularly the trailing edge, which is optimized to reduce turbulence and meet the air flowing through the helmet. This maintains linear airflow off the helmet and rider, improving the riders overall aerodynamic performance. In addition to the ventilation and aerodynamic performance, the Procen also utilizes a new and innovative 2 position lens system which allows a rider
