I ordered these glasses in 092016 we are now 082017, they are awesome sunglasses, with a very comfortable nose piece, they are stamped Z87. The only thing I highly recommend you "NOT" doing is leaving them in a car on a hot day, I did so and my nose piece melted and warped, I had to cut it to make the glasses wearable, other than the nose piece being warped from heat the lenses and temples were still in perfect condition! Other than that these glasses are awesome and I am ordering more pairs!
