Say goodbye to foggy visors with The Helmet Shop DKS238 Clear Anti-Fog Pinlock Insert, precision-engineered for the HJC HJ-31 Pinlock-ready shield used in the i10 and i70 helmet models. Whether you ride in cold weather, rain, or humid conditions, this insert keeps your vision crystal clear when it matters most.

By working in conjunction with the HJ-31 shield's built-in Pinlock pins, this insert transforms your single-pane visor into a high-performance dual-pane system — the same technology trusted by riders in MotoGP and World Superbike racing.

• Dual-Pane Anti-Fog System: The moisture-absorbing Pinlock lens and airtight silicone seal create an insulating air pocket between the insert and your shield, acting as a thermal barrier that prevents warm helmet air from meeting cold outside air — eliminating condensation at its source.
• Moisture-Absorbing Nanotechnology: The lens surface actively attracts and stores water molecules, releasing them as humidity drops so the insert is always ready for your next ride.
• Optical-Grade Clarity: Crystal-clear optical material delivers distortion-free vision with excellent light transmission for safe riding in all conditions including rain, cold, and night riding.
• Adjustable Eccentric Pins: The insert mounts between two adjustable eccentric pins on the HJ-31 shield, allowing you to fine-tune the silicone seal tension for a perfect, airtight fit.
• Tool-Free Installation: Snaps easily onto existing HJ-31 shield pins — no adhesives, no tools, no helmet modifications required. Watch the installation video by scanning the QR code included in the packaging.
• Yellow Protective Film: The insert ships with a yellow factory film to prevent scratches in transit. Peel it off as the final step of installation to reveal the clear anti-fog lens underneath.

Compatible HJC Helmets: i10 | i70

Compatible HJC Shield: HJ-31 (must be Pinlock-ready with built-in connection pins)

Note: This insert is model-specific and not a universal fitment. The Pinlock lens is made of soft moisture-absorbing material and is less scratch-resistant than the face shield — handle and store with care. Helmet not included.
