The Main X Stray Goggles deliver trail-ready functionality. All-weather performance is maximized with the use of a dual-paned Lexan lens to reduce fogging on cold, wet rides. Ounce-for-ounce, the Main Goggles are the best value on the market, and feature our 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.
