I am a big fan of the Mag Four. I have three pairs right now. I have the denim frame with black iridium lenses, black carbide with persimmon lenses and most recently I got the plasma frame with fire iridium lenses. Unfortunately the plasma frame didn't really work out for me. They look too small on my face (I know what what you may think, those might be the Mag Four S. They are aren't. I double checked to make sure.) There is a silver lining, I was able to take those fantastic looking fire iridium lenses and put them on my denim frames. Check out the photo below! I think it looks pretty good. I'll be rotating lenses when needed. Changing the lenses on the Mag Four isn't really difficult although I highly recommend you keep track of where the screws are when you do this. I need to find a new home for the Mag Four plasma frames, I guess eBay will have to do. But long story short, I GOT NEW MAG FOUR FIRE IRIDIUM LENSES!!!!!!!
