Ray-Ban offers the familiar RB4187F Chris Alternate Fit sunglasses for the man who wants comfortable, timeless shades. The sleek square rims are crafted in hypoallergenic propionate—a lightweight but durable nylon material. Crafted in sturdy, corrosion-resistant metal, the thin temples feature wide, comfortable socks over the tips for added grip behind the ears. An alternate fit design prevents slipping on the nose, ideal for the man with high cheekbones and a wide nose bridge. Ray-Ban branding on the temple and lens adds cool, retro appeal to these RB4187 Chris sunglasses.
