Inspired by the helmet visors of fighter pilots, the medium-sized fit of Flight Deck M maximizes your field of view so you won’t miss a single target of opportunity. It was engineered for seamless compatibility, giving you the flexibility to choose the helmet that fits your style. Designed with Oakley’s Ridgelock Technology, changing lenses is quick and easy while still allowing for a complete lens seal to prevent harsh conditions from penetrating into your goggle. Prizm is a revolution in lens optics built on decades of color science research. Prizm lenses provide unprecedented control of light transmission resulting in colors precisely tuned to maximize contrast and enhance visibility.
