Black Leather Biker

Looking for old 50s style bikers sunglasses black frame with black or mirrored blue lenses. They had a thin soft leather attatched to the frame and the temples of the glasses, in almost a half round v shape.. The attatched leather created a seal between the frames and the wearers face blocking wind, dust etc. When folded up the leather would simply fold into place. Last time I had a pr was about 12yrs ago. Does anyone know where I can find them...Thank you
