The Fox Racing Main Core MX Goggles in fluorescent yellow feature the Variable Lens System (VLS). VLS makes your goggles compatible with both standard lenses (stock) and injection-moulded lenses (sold separately) within the same frame. These offer a wide viewport that provides exceptional peripheral vision with a Lexan lens that offers UV protection. They meet the EN1938:2010 standard and boast triple-layer face foam with a fleece liner, a strap-mounted third tear-off post, and a non-slip silicone strap. They also come with a Microfibre goggle bag. Clear lens.
