The sunglasses themselves are fantastic
"The sunglasses themselves are fantastic and absolutely worth the money. The optics, comfort, and overall quality are excellent. The main reason I purchased them was for the Z87 rating for work, where side shields are required. Unfortunately, the included side shields are hot garbage. They slide around with even slight head movement, and if you look up too far, they fall off completely. Overall, the glasses themselves are outstanding, but the side shields could definitely use a redesign or a more secure fit to match the quality of the frames."
