Rapper B.o.B (Bobby Ray Simmons, Jr.) wears Persol 714 folding sunglasses in the music video for his song Lean On Me featuring Victoria Monet.

The details (nosebridge hinges, side Persol hinges) of these classic sunglasses, made famous by Steve McQueen, can just be seen under baseball cap of B.o.B in the black and white video. The color of the glasses is tortoise.

Get the glasses online at the official Persol store, or at Amazon.com, Amazon.co.uk, eBay (a good source for the Steve McQueen version with blue lenses).
