Ray-Ban © RB4187 Chris sunglasses are a stylish new addition to our Highstreet © collection. This unisex frame takes style cues from the RB4171 Erika, but features a more masculine, squared-front shape alongside the unique key bridge. A gummy, rubberized finish give these sunglasses an exclusive textured feel. Thin, elongated temples have the Ray-Ban © logo etched elegantly onto the metal. RB4187 is also available in a variety of fun colors that set you apart from the crowd.
