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.
