The Oakley Fall Line M provides a fantastic range of view, paired with a medium frame size. Full ventilation and an anti-fog coating to keep lenses clear, and Oakley's Prizm lens technology for increased contrast and definition whilst sliding on snow. A frameless design combines with a cylindrical lens to provide a great field of vision with sharp, modern styling. Designed to integrate seamlessly with many helmet shapes. We find that pairing the Oakley Fall 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. Oakley Prizm lenses keep things simple, allowing you to use one lens across a broader range of conditions. Why change lens, when you don't have to?
