The Fox Main Cycling Goggles are the best value on the market. New for 2020 is Fox's own Variable Lens System (VLS). VLS makes your goggles compatible with both standard lenses (stock) and injection molded lenses (sold separately) within the same frame. With an expansive viewport, triple-layer foam and tear-off lens functionality, they are a heavy hitter and light on the wallet. They also feature a Spark lens which is a mirrored lens that helps improve visibility and reduce glare in bright daylight.
