Diffuser Type 10: It features the new 'Air In Stabilizer', an additional air intake between the front and rear air intakes, and wider levers. The incoming air intakes help facilitate the exit of air from the rear of the helmet, increasing airflow without enlarging the holes in the shell.
The redesigned and well-aligned air intake allows for greater airflow inside the helmet using the same 10 mm holes. This new diffuser guides more air in and out, utilizing an aerodynamic design instead of larger and therefore noisier and less aerodynamic air intakes.
The redesigned Delta Duct 5 air intake increases airflow and helps reduce noise. Thanks to this new ventilation system, the temperature inside the helmet decreases much faster compared to previous versions. One size fits all, from XS to XL.
