<p>The helmet (10) has a cap (13) placed within a protective shell (11). The shell includes projections (31) defining air flow channels (34) between a front of the cap and a rear part of the cap, where the projections face the head of a user, and the air flow channels are fed by a front opening of the protective shell. The projections are arranged to form the air flow channels having a path projected on a horizontal plane, irregular in a longitudinal direction of the helmet, so as to disrupt the flow of incoming air flow.</p> |
