I think that when it comes to Oakley M Frames, some people love them while others totally disregard them. Because of their price tag (which I personally believe is quite reasonable), you should first consider if Oakley M Frames are for you. I think they are a great choice if you want great vision and you don’t lose your sunglasses all the time. It’s a fact that Oakley produce the best lenses when it comes to sunglasses, and I especially like the Pro M’s fit. The way they just lay on your face and you can just forget about them. It’s like you are not wearing them. What I look for in a product is that, once I start riding, it just does what I want it to and I don’t notice it.
