A dual-paned Lexan lens gives FOX’s Main X Goggle an advantage over the elements. It blocks out moisture, dirt, grime, and fog whilst offering a widened field of view. It’s still lightweight and comfortable with FOX’s triple-layer face foam serving as yet another shield against moisture build-up, but it packs a serious punch into such a simple frame. The Main X frame is compatible with both standard lenses and injection molded lenses, giving these goggles a bit more versatility. Each lens acts as a barrier between the elements and UV rays and offers a great sense of clarity in the periphery, too. When combined with the flexibility of FOX’s do-it-all frame, the Main X Goggle’s lenses offer some heavy hitting performance for an exceptionally valuable price.
