PINLOCK MAX VISION helmet adhesive clear anti fog insert lens Motorcycle and scooter LS2 FF390 FF397 integral helmets REF: 800400020 Not every helmet is Pinlock prepared. This doesn’t mean that there is no anti fog solution possible. PINLOCK lens is the answer! It is an adhesive anti fog insert lens which fits only LS2 FF390 and FF397 integral helmets. The PINLOCK insert is made of a moisture absorbing plastic and, therefore, the surface basically dry when used. The insert also has a silicone seal that creates a double shield between the visor and the PINLOCK insert. The air-tight pocket ensures that the difference in temperature becomes significantly lowered. The PINLOCK insert absorbs moisture on the inside and offers you continuous clear and high visibility. PINLOCK clear adhesive lenses are perfect for use all day long.
