Ounce-for-ounce, the Main Drive Goggles, are the best value on the market for side-by-side/UTV adventures, and feature our Variable Lens System (VLS). VLS makes your goggles compatible with both injection-molded lenses (stock) and standard lenses within the same frame. With an expansive viewport, triple-layer foam with a fleece lining, and tear off functionality, they are a heavy hitter that's light on the wallet.
