Oakley Ski Goggles Flight Tracker XM OO7105-11 Matte White Prizm Snow Persimmon extend the field of view in all directions due to its oversized design. Based on a tried-and-tested architecture, a full-rim encases the lens and reduces movement and distortion during use, whilst triple layered foam increases airflow to aid the elimination of fogging. Engineered to fit a broad range of face shapes, the XM is the medium sized version and will also fit perfectly with most helmets.
