The Oakley Target Line M has a medium frame size that provides a great range. of peripheral vision. The Target Line, whilst not having all of Oakley's top end features, offers a great blend of performance on a budget.  Full ventilation and an anti-fog coating to keep lenses clear, and Oakley's Prizm lens technology for increased contrast and definition.  Designed to integrate seamlessly with many helmet shapes. We find that pairing the Oakley Target Line M with a Medium/Large helmet provides the best fit & comfort. Oakley goggles have a unique face foam shape in the nose area to provide a gap-free-fit for both high and low nose bridges. This added foam eliminates the need for Asian-fit models.
