Issued to Gemini and Apollo astronauts as part of their survival kits, American Optical's Original Pilot sunglasses are true classics. Popular among US military pilots and NASA astronauts, they're built in the USA to military specifications. Those include a sturdy, 23K gold-plated frame with comfortable stems and nose pads, bayonet temples that make them easy to put on or remove while wearing a helmet or headset, and impact-resistant Calobar green nylon lenses. They arrive with a brown leather carry case.
