As a world-class tennis player, Roger Federer is a force to be reckoned with. Here, the athlete teams up with Los Angeles-based eyewear brand, Oliver Peoples, to create a pair of sunglasses that combines exceptional craft with unique, practical detailing. Thus, the Mr. Federer ii sunglasses are made from lightweight co-injected bio-nylon frames with steel wiring that can be seen on the temple bars for a stripped-back effect. If you look closely at the 100% uv protective lenses, you'll see a small ‘rf' monogram delicately engraved on the side.
