The WileyX SG1 replacement lenses are just as tough as the originals. I used these sunglasses in Afghanistan with my deployment and they are continuing to serve me back home. They finally needed more replacement lenses and the ones ordered fit the bill just fine. I would order again and as stated before, they are just as good as the original.
Pros: Easily ordered, easily put in and easily used
Cons: None
