A patented visor release system ensures the visor detaches at a predetermined force to help reduce neck loads during an impact.
Ten inlet vents and seven exhaust ports maximize airflow and heat exchange for extended riding comfort.
Internal layered construction provides energy management and durability for consistent protection.
