The Ray Ban RB4179 601S9A Men's Sunglasses are the perfect combination of iconic style and cutting-edge innovation. These Square sunglasses feature a sleek Dark Green frame made from a new bio-material, a semi-crystalline thermoplastic commonly used in aerospace, automotive, and medical technologies. This innovative material ensures superior lightness, durability, and comfort. The P3 polarized polycarbonate lenses provide exceptional clarity and enhanced vision, while the hydro-oleophobic coating protects the lenses from liquid smudges and stains. The injected construction of the top bar allows for a thinner frame, providing the same strength as metal frames. With a lens size of 54mm, these sunglasses deliver both function and style for men on the go.
