Oakley has expanded the popular flight deck family with a mid-sized fit, made for smaller faces. The new Flight Deck XM was inspired by the helmet visors of jet pilots and maximizes your field of view so you won’t miss a single target of opportunity. Peripheral and downward vision is wide open for spotting your line, and the new ridgelock interchangeable lens system lets you adapt to whatever the sky dishes out. None of these pilots would take off without a helmet, so the Flight Deck XM was engineered for seamless compatibility with all leading helmet brands. With clean style, an open field of view, ridgelock lens system and maximum comfort, this goggle will dominate the skies for years to come. Take your board - you’re set to fly fo’ sho’!
