Ray-Ban ® RB4126 CATS 1000 sunglasses are a bold, unique sampling of everything that makes Ray-Ban's design aesthetically timeless, original, and unmistakable. Their shape is slightly reminiscent of the popular Wayfarer ®, but the large rounded lens shape separates the CATS 1000 from other styles in the Ray-Ban collection. Lens width: 57mm Lens material: Glass UV filter: 100% Case type: Hard
