Serengeti Sunglasses Carrara 8546 Shiny Gold Gold Drivers Mineral Polarized are a classic pilot style, with the iconic teardrop shaped lenses and double bridge. The temples have a hidden double flex spring hinge for a wider fit range for an updated version of the very popular pilot, here in the smaller size model. Photochromic lenses are Serengeti’s speciality and the lightweight lenses will darken or lighten exceptionally well in differing light conditions.
