As the 1970s marked a turning point in American culture, society, and politics, so too does the 1970s-inspired BULVAN marks a turning point for aviators. It's lightweight, and made of metal, but this double-bar aviator also features acetate temples and an acetate bridge for added comfort...like we said, revolutionary. Handcrafted using a combination of metal and Italian acetate. Comfortable double-bar with acetate nose bridge. Includes acetate nose pads. Moscot temple engravings.
