Ray-Ban RB4258 sunglasses for men feature a bold profile and a keyhole bridge for a timeless look with a fresh vibe. Ray-Ban crafts these rounded rectangular frames in lightweight but sturdy propionate nylon, engineered to take on any sunny-day adventure. The wire-core shark fin temples curve inward gently for added stability behind the ears. Embellished with signature studs on the rims and the raised signature Ray-Ban logo on each temple, these sunglasses are at once familiar and stylish. For the man unafraid of a vintage-leaning look, the Ray-Ban RB4258 makes a winning choice.
