Oakley's most popular goggle, the Oakley Flight Deck XM Prizm Goggle is the scaled down version of the Flight Deck for people with slightly smaller faces and do not want to look like a bumblebee wearing big goggles. With Oakley's Prizm Spherical lens quality and its frameless design, the Flight Deck offers distortion free vision and an unrivalled field of vision. The revolutionary Prizm lens technology dramatically enhances contrast and visibility over a wide range of light conditions. The lenses are also highly impact resistant to keep your eyes extra safe. The Flight Deck XM is also 'OTG' (Over the Glass) compatible catering for people who need to Ski and Board with Prescription Eyewear.
