These unisex Ray-Ban Chris sunglasses are designed with unique style cues taken from the Erika style, but spun into a slightly more masculine shape with square lenses and a less circular frame shape. Chris RB4187 sunglasses have been crafted with a gummy and rubberized frame finish, giving these trend setting sunglasses an exclusive textured feel. The Ray-Ban Chris epitomizes modern day fashion packed into a lightweight, comfortable design.
