Square-profiled, military-inspired aviator sunglasses have been making a strong resurgence this season, thanks due in part to the popularity of a certain Mad Men character. Oliver Peoples has just partnered with American leather craftsmen at Parabellum for this limited Lindford Aviator package. This vintage aviator comes in a black or classic gold frame and features rich handmade acetate inserts in each earstem which resemble a natural bison horn. Parabellum’s contribution to the package consists of a case handmade from supple American bison leather and lined with a soft lambskin. You can look for this collaboration from Oliver People boutiques starting on September 1, where it will retail for $695 USD.
