Ray-Ban Active Lifestyle RB3519
The glasses worn by Ice Cube have a black matte metal frame and polarized lenses (you can spot the P next to the Ray-Ban logo on the lens).
In this sequel to Ride Along (2014), Ice Cube reprises the role of detective James Payton.
These sunglasses are available at SmartBuyGlasses (best deal), or Amazon.com and eBay. Watch out, there are a few scam websites selling fakes very cheap - an original pair, especially polarized version, should cost anywhere between $120 - $160.
