説明By improving the design of traditional sealing rings, the field of view has been significantly improved. Flight deck pro's field of view is 7% wider than a normal flight deck, giving more confidence in dealing with various terrains. The anti-fog coating is fused directly to the outer lens to reduce image distortion and improve clarity under various conditions. Each flow scape lens uses prizm™ snow optical technology to fine-tune contrast and help show more details in snow, sunshine and shadows. Flight deck pro is equipped with two external mechanical locks for quick lens replacement, ensuring lenses are firm. Unlike other switchlock models, the flight deck pro does not use magnets to expand the field of view. Each pair of flight deck pro is equipped with a dual lens set, making it easy to change lenses and quickly adapt to changing light conditions, allowing you to stay on the snowy mountains for longer.
