The Oakley Radar Path was my first pair of Oakley and I absolutely love it. Mine is the Asian fit model with the Carbon Fiber frame. Model ref number 09-740J. Its really worth my money. Its lightweight, durable and is very comfortable. It fits my face perfectly, no slips whatsoever thanks to the good rubber/unobtainium grips of the nose pad and the earstems. Probably the most comfortable pair of shades I've ever worn. The clarity of the lens is just fantastic, Oakley's High Definition Optics (HDO) at its best! I use the Radar regularly for cycling as well as for daily use. This pair of shades turns heads as well cause it looks really attractive with its sleek futuristic look. And the interchangeable lenses is the best part so I won't get bored with the same lens all the time as I can change the lens to a different colored one anytime and its very simple to remove and install lenses. Additional replacement lenses come separate of course and are quite pricey depending on the style. But other than that, as far as I know, I can't find any cons for my Radar Path so far. Thank you Oakley!!!
