One size does not fit all, so Oakley has expanded the popular Flight Deck family with a mid-sized fit. Inspired by the helmet visors of fighter pilots, Flight Deck XM 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 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. Packaged with the Fine Knit Beanie, it is made with soft, fine-gauge knit fabric so you stay warm on and off the mountain. Embroidered ellipse logo lend subtle style to this comfortable Oakley beanie
