Say hello to a legend. Making a major comeback, is the Porsche Designs 8478 aviator. Introduced in 1978, these extremely lightweight titanium frames were a marvel when first released. What makes them so special is the interchangeable lenses, which securely fasten into place with strong clamps. As far as we’re concerned, this greatly enhances their appeal.

With a delicate bridge and thin rims, these retro unisex shades, give any wearer an immense amount of authority. Available here.
