Originally issued to soldiers of the German Army, these goggles were used to protect their eyes from dust, wind and UV radiation. These were first released during WWII though the ones we have here are dated from the 1960s. The unique folding design allows the goggles to be contained in a vinyl envelope (included) and stored in your pocket. An adjustable elastic strap allows the goggles to fit over most sized heads while the soft velvet frame sits comfortably around your eyes. The dark tinted lenses are ideal for reducing bright sunlight. Whether you're needing a practical pair of goggles to keep the dust out, you're a collector, or you like getting weird looks in public, these are the goggles for you!
