The Fox Main Core MX Goggles feature the Variable Lens System (VLS). VLS make your goggles compatible with both standard lenses (stock) and injection-moulded lenses (sold separately) within the same frame. These offer a wide view port that provides exceptional peripheral vision with a Lexan lens that offers UV protection. It meets EN1938:2010 standard and boasts triple-layer face foam with a fleece liner, strap-mounted third tear-off post and a non-slip silicone strap. Comes with a Microfibre goggle bag.
