Eliminate fog! The RAZOR 2 ZERO model, equipped with a cylindrical lens, is perfect for protecting the face from cold air and thus reducing fog formation. It is ideal for individuals with medium to large face sizes. Available with a category 1 lens, the RAZOR 2 ZERO is designed for use in overcast or snowy conditions. The yellow tint of the lens enhances visibility of terrain contours, making it easier to navigate through snow.
