The new SM5 helmet is the result of over five years of intense study, development and testing. Data sheet: The lightweight outer shell is constructed from a technologically advanced impact resistant thermoplastic in two dimensions. The internal and external surfaces are designed to minimize the effects of oblique impacts. Multiple density inner lining to ensure the correct density in the correct area for increased impact absorption.The patented visor release system ensures that the visor is released with the right predetermined amount of force, regardless of the angle of impact. Optimized ventilation and high levels of heat transfer exchange thanks to multi-air inlets and exhaust ports. The visor was designed to direct air into the ports for increased airflow. Pair of side shells with soft EPS foam prevents collarbone damage in the event of a crash.
