ABSTRACT:
A helmet with large vent openings includes a vent shield to prevent the penetration of foreign objects and a vent airflow regulator positioned over the vent shield so as to regulate the amount of airflow allowed within the interior of the helmet. The vent shield is attached to the foam liner during the in-mold process, while the vent airflow regulator is positioned behind the vent shield after the in-mold process in a post-applied manner. A foam insert is positioned behind the vent airflow regulator and also has vent openings.
