1. A helmet comprising:
a shell having an inner surface defining a cavity and an outer surface, the shell further having a front section provided with an opening;
a visor operatively coupled to the shell and adapted to cover the opening;
a ventilation system, comprising:
a ventilation channel integrally formed with the shell and being adapted to enable fluid flow therealong, the ventilation channel having a converging-diverging section configured to create a pressure differentiation along the ventilation channel and increase velocity of the fluid flow along the ventilation channel;
a ventilation inlet provided along the inner surface of the shell and being adapted to establish fluid communication between the cavity and the ventilation channel;
a ventilation outlet provided along the outer surface of the shell and being adapted to establish fluid communication between a surrounding environment and the ventilation channel downstream of the converging-diverging section; and
an auxiliary inlet provided along the outer surface of the shell below the opening and being adapted to establish fluid communication between the surrounding environment and the ventilation channel upstream of the converging-diverging section.
