If you've got a pair of Smith Fuel goggles with a scratched up lens, or you need a different tint to suit the conditions at hand, look no further than the Fuel MTB Goggle Replacement Lens. If you'll be riding in sunny conditions, choose one of the mirrored lenses and enjoy exceptional glare reduction and optical clarity. For conditions with variable light, choose one of the ChromaPop lenses for enhanced contrast and definition. And of course, there's an anti-fog clear lens for overcast weather or riding in deeply forested terrain.
