This Torga Mission 6 frame has a medium to large fit. This sporty look and included flexi-tint prescription lenses is a complete visual solution for cyclists as the lenses are clear in the early morning (and indoors), and gradually darken outdoors in as they are exposed to sun. The included flexi-tint lenses also protect your eyes against UV radiation and are non-polarised to increase visibility of certain hazards such as water on the road.
