HJC HJ-43 Pinlock A Pinlock lens is made to enjoy a fog-free ride. It is based on two key principles to ensure a fog-free vision. The moisture absorbing surface of the lens effectively attracts and stores water molecules, while the airtight seal creates a thermal barrier together preventing condensation of the visor. The system is kept in place by positioning the lens between two adjustable pins, making Pinlock the number one anti-fog solution for helmets. -Ready Face Shield
