Revo lenses are definitely superior to Oakley or Wiley X, which I have.  I originally purchased the Revo Headway frames but they were heavy and even after 30 minutes you could really feel their weight on your face.  The Bearing frames are a bit lighter.  Not sure why Revo makes their frames so heavy, and the weight issue is probably why they don't list the weight of each model on their website.  My Oakley and Wiley X frames are super light, if not for the quality of Revo's lenses I would not have purchased these.  Another drawback to these frames is they do not provide you with a 100% unobstructed view, whereas my Wiley X Romer II model does.  I'm giving these 4 stars solely based on the quality of the lens.  If I could get either my Oakley's or my Wiley X frames with Revo lenses then you wouldn't be reading this.
