The HJC F31 helmet combines an Advanced Fiberglass Composite (AFC) shell with practical features for everyday riding. Its Double-D ring closure uses a pull tab for secure fastening, while the dynamic multi-step sun shield allows optimized positioning. The helmet is ready for SMART HJC 2nd Generation 11B, 21B, and 50B Bluetooth systems, which are sold separately.

The interior is moisture-wicking, quick-drying, and odor-free for a more comfortable ride. The crown and cheek pads are removable and washable, and the cheek pads are interchangeable between all sizes. This helmet includes an HJ-43 visor that is Pinlock prepared, anti-scratch coated, and designed to provide 99% UV protection.

HJC Advanced Channeling Ventilation System (ACS) helps move airflow from the front to the back of the helmet, flushing out heat and humidity. Ventilation is provided through three intakes and one exhaust. The F31 is finished in N Gray and identified by part number JA21NUS3XGNV.
