I've had these for several years now and recently had photochromic lenses installed to make them even more versatile. They are weighty, but rock solid performers, and certainly comfortable for short duty "readers". The frame is shaped much like my beloved Wiretap 1, but the lens shape less radical. I'm actively searching for another pair.

I totally agree. I just bought them and I absolutley love them. The fit and form are just great. They are definitely a tad bit heavy though, though I just see that as a sign of quality. I am, and have always been an Oakley fan, and I personally think you cannot get a finer pair of glasses (prescription or sun) for the price. So, as I said, the weight just lets me know they arent going to simply bend and fold with the slightest bit of pressure from something unexpected happening. So I dont mind the little bit of extra weight. I know they are going to last. Weight = quality... In this case anyway... LoL. Not ALWAYS the case though, obviously... LoL

Frame: Midnight blue
Lens: clear
Cool frames and very stylish. A little heavy if you wear them for long periods. I would not buy these if I had to wear them all day long luckily I only need them for driving.

Frame: Oakley RX Straight Line 4.0
Lens: RX clear


Good stylish frames - but I agree after wearing Nike flexon frames for the last year these bad boys are heavy.

very stylish Oakley Rx frame, got the brown one too...
a tad heavy though, will likely not choose a C5 alloy frame from Oakely again.
