The Pinlock 70 is premium fog resistant solution for riders. Enhanced with stronger fog resistant properties, the insert lens has extended fog resistant endurance which helps riders see better through challenging weather conditions. The Pinlock 70 creates a double shield system through a silicon seal between the helmet face shield and Pinlock insert lens, which makes up a double glass type of solution that prevents fogging. The insert is made of a moisture absorbing plastic and therefore, the surface basically dry when used. This 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 visibility.
