One size does not fit all, so Oakley has expanded the popular Flight Deck family with a mid-sized fit. The new Flight Deck XM was inspired by the helmet visors of fighter pilots and maximizes your field of view so you won’t miss a single target of opportunity. Peripheral and downward vision are wide open for spot ting your line and the new Ridgelock interchangeable lens system lets you adapt to whatever the sky dishes out. Discreet frame notches at temples provide compatibility with most prescription eyewear. The Flight Deck XM was engineered for seamless compatibility, giving you the flexibility to choose the helmet that fits your style.
