The Ray-Ban RB4147 design for men is reminiscent of a navigator style with a strong and defined shape but with slightly softer lower frame edges for a more flattering and wearable finish. The top section of the acetate frame subtly dips at the bridge and the acetate straight arms are relatively thick, adding to the strong and prominent aesthetic appeal of these sunglasses. The arms also display the Ray-Ban signature logo adjacent to the arm hinge in addition to the logo being etched on the lens. The Ray-Ban RB4147 frame colours vary ranging from classic black, to tortoiseshell in addition to a two-toned combination of a white frame with contrasting black arms and a black frame with blue arms. Most of the Ray-Ban RB4147 lenses are either grey or brown toned, some with a gradient or graduated finish and some with a crystal or polarized finish for maximum eye protection and enhanced visual clarity. This style is statement but versatile and continues to look great season after season.
