Inspired by the helmet visors of fighter pilots, the large-sized fit of Flight Deck maximizes your field of view so you wont 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 Oakleys 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.
