If you are looking for sunglasses for mountain biking, then there is nothing better than the fake m frame oakleys. When I saw the price for the first time, I almost wanted to buy cheaper specs. But the quality convinced me to buy Oakley. Although M Frames are expensive, they are worthy every dollar spent. I have been using them a year now, as a result they got some scratches, but still they perform well. Handle with care. The lenses are of the highest quality, the fit is perfect, look good on almost anybody and most of all, they don’t fog up during the ride.
