The Complex Laminate Construction (CLC) method requires precise and laborious assembly by master craftsmen from several individual pieces.

The easy-to-clean diffusers make strong venturi suction on the back and center top vent for developed airflow. The air intake below the peak collects and directs cold air into the Arai VX Pro 4. The internal ventilation shutter of the chin guard prevents dirt from entering the helmet in dusty driving conditions. Google ventilation and lower lateral vents.

5) Peak

The Arai VX Pro 4 peak sweeps and forces air into the ventilation holes in the forehead to cool while at the same time using multiple relief ports to decrease lifting at the higher speeds.
