The 13-Five is perhaps our most comfortable goggles yet. The low profile lens format is a perfect fit over the brows but under the helmet. It's made with a multi-layer foam that's soft enough to wear for long hours. The spherical lens gives you a great distortion-free view with totally unobstructed peripheral vision. All 13-Five lenses are 100% UV blocking and impact-resistant. These goggles come with their own microfiber carrying case that can be used to clean the lens.
