The MTB Main Goggles have been specifically designed for mountain bikers and can be worn with both full-face and 3/4 shell helmets. They offer the best value for money on the market and feature our variable lens system (VLS™). VLS™ makes your goggles compatible with both standard lenses (included) and injection-molded lenses (sold separately) within the same frame. With their wide field of vision, triple-layer foam, and tear-off function, they are a true powerhouse while being easy on the wallet.
