The Pinlock 70 lens is the result of two decades of fine tuning to create the perfect anti-fog lens for daily motorcycle commutes and weekend rides. The Pinlock® lens is made to enjoy a fog-free ride. It is based on two key principles to ensure fog-free vision: the moisture absorbing surface of the lens effectively attracts and stores water molecules, while the airtight seal creates a thermal barrier preventing condensation of the visor. The system is kept in place by positioning the lens between two adjustable pins.
