The Ray-Ban Flacko is a bold rectangular frame built on daring proportions, with an ultra-defined brow line, thick profiles, and angular edges. Finished in polished Black with solid Green lenses, it carries the distinctive metal Hawkeye temple design and molded acetate temples — a blend of archival Ray-Ban reference and contemporary weight.
