Frame: Crystal Black
Lens: Black Iridium

Won these in a SGH contest while I worked there. They're great. I love to just throw them on when I'm heading to the beach.

Frame: SI Black
Lens: Grey
I got these as an everyday pair for work (firefighter/fire safety inspector). These are MUCH better than I imagined. Though they lack unobtanium, they perform well. Sporty yet professional. I don't know about wearing them with a suit but that's just me. I like the rimless lens and the ability to swap them out. Very simple frame with the silver O accents. It's basically a watered down flak jacket. Great buy! I use mine for everyday use (driving, walking around). They took the place of my Fives 2.0 (I still have them but will now use them as a backup pair). I don't know how they'd perform in an active, sporty, or hectic environment (I have others pairs for that!) but as a normal use pair, they're great!

Frame: Black Chrome

This is one of those glasses that the frame color makes a huge difference in how they look on a person. The only colors that I like are Black Chrome and Crystal Black. All the others just don't seem right to me. With that said, I like the ones I'm partial to very much. They feel like a much more casual version of the Half Jacket. You could get away with wearing a pair in a suit when a sportier frame would look out of place.

Frame: Polished Rootbeer
Lens: Bronze

I like the fit of these more than the half jackets. These are a bit better for the bigger heads. However, I'm still somewhat bored by the frames and square lenses. While the quality of Oakley is present, I think the design is missing. Still, these get as much use golfing as my M-Frames.

Frame: Polished Black
Lens: Black Iridium Polarized

These are my favorite Oakleys. While they might not be as stylized as some of Oakley's other frames, the sleekness and simplicity of the bottlecaps is what makes them so versatile and enjoyable to own. Because they are a slightly more conservative style, they make a great casual everyday pair of glasses but are also sharp and sporty-looking enough for more demanding activities. They stay on my face great despite the lack of unobtanium on the earstems and nosepiece (although it could be a different story if I wore them running and worked up a sweat-they are still fairly new and I haven't worn them for anything too physically demanding yet). They also do a great job of conforming to my face and the peripheral vision that they provide is superb (one of my chief complaints about some of Oakley's full frame models is lack of peripheral vision). I would definitely reccommend this lens/frame combo...the polarized lenses privide very sharp vision and the black iridium is very slick looking. For the price, this is a great set of shades!
