VENTILATION SYSTEM
The exclusive ventilation system, complete and extremely effective, makes the best
use of three different air ows: one front air intake, two upper ones and two rear air
extractors.
These ensure optimum air circulation inside the helmet.
A Completely closed system (Closed front air intake and closed upper air intakes)
(Fig. 23A)
B Completely open system (Open front air intake and open upper air intakes)
(Fig. 23B).
