The SA2015 Vortex™ Forced Air helmets come with a unique six pad
interior system which allows for resizing the helmet for a perfect fit
along with corrugated ridges which allow for better heat transfer. The
interior forced air channels were further improved upon, by increasing
ventilation pressure and improving airflow to be directed to a critical
area of the helmet. additionally, the inclusion of strategically
placed ventilation ports around the top of the head provides optimal
cooling throughout.
