Original Wehrmacht issued sun and dust goggles. This is a reasonably good example. The elastic is a bit stiff and I doubt it will do any stretching but you can adjust the strap well enough. One of the little vents in the leather is missing. The lenses are removable and replaceable. If you intend to use these for your motorcycle I would recommend making new lenses from safety glass. These would have originally had a small imitation leather pouch, but this pair does not.
