The category S3 windscreen is designed for riding in strong and harsh sunlight. It will work well for people who are hypersensitive to light and on high-altitude slopes without shaded areas. It absorbs between 82 and 92% of light and has a darkened surface.

A polarising filter effectively protects against glare from light reflecting off the surface of snow or another flat surface such as water. In addition, it enhances contrast and colours, which improves the driving experience and reduces eye fatigue.
