Pinlock – Fog Free Systems.
Pinlock Fog Resistant Visor inserts ensure you have a clear view whatever the weather conditions. Pinlock is created out of a moist-absorbing plastic and the silicone seal on the Pinlock creates an air tight double visor. It is easy to fit - placed between two adjustable pins - and the system is interchangeable making it easy to switch visor inserts when the weather changes. Pinlock can be used all year round during hot and humid conditions and wet; cold periods and makes riding with a completely closed visor entirely possible without any visor misting.
