Product Information

Full details

The HJC i31 Open Face Helmet is an ideal choice for urban commuters and touring riders who prioritize comfort, breathability, and versatile protection. Featuring a lightweight polycarbonate shell, this helmet integrates a dual-visor system and advanced airflow technology to keep riders cool and protected from glare. While it offers excellent visibility and comfort for glasses wearers, users should be aware that as an open-face model, it provides less chin and lower-face protection compared to full-face alternatives.

Troubleshooting

Visor is fogging up

Pros and Cons

Pros

  • Excellent ventilation thanks to ACS technology
  • Easy-to-use integrated sun shield
  • Lightweight construction reduces neck fatigue
  • Glasses-friendly fit
  • Quick-release mechanism for visor changes

Cons

  • Open-face design leaves the chin exposed
  • Less wind noise reduction than full-face helmets

Setup, Compatibility & Care

To ensure the best fit, verify the helmet sits level on your head with the cheek pads touching your face firmly. To clean the helmet, remove the crown and cheek liners and hand wash them with mild soap and cool water, allowing them to air dry completely before reinstallation. Keep the HJ-43 visor surface clear of debris by using a soft cloth and non-abrasive cleaners. If installing a Pinlock lens, ensure the pins are properly seated to create a vacuum seal. Always store the helmet in a cool, dry place away from direct sunlight when not in use.
