• The outer shell is made of a blend of aramid fibers and fiberglass, providing strength and lightness
• the smooth profile is aerodynamic and free of external features that could act as load points during impact

• MIPS® system to mitigate the causes of traumatic brain injury
• a unique, patented shield release system that provides a secure fit when riding on the roughest terrain, while providing enough resistance for the shield to detach from the helmet in the event of a significant impact

• removable chin vent for additional airflow
• removable air filter on mouth opening for easy cleaning
