These glasses are in excellent condition with no signs of wear or scratches. Formerly known as the FG-58, Original Pilot gold square aviator sunglasses were first developed in 1958 for the needs of American military pilots. By 1969, they had been to the moon as part of the survival kits of all Apollo astronauts. Still made in the USA from premium global components, still engineered to rigid military specifications, these non-polarized aviator sunglasses are built to last with 23K gold plating, durable yet lightweight nylon lenses, sturdy and comfortable PVC click-in nosepads, and bayonet-style temples that allow you to remove your glasses without taking off a helmet or other headgear. Size 55-20-140 mm fits many face shapes. Style: Bayonet Lens Color: Calobar™ Green Frame Color: Gold Lens Type: AOLite™ Nylon
