It doesn't have a fancy name and its a rather unexpected product from a optics company but its a very fine case.
It's not a thin case, no its not the Incase Slider at all. It is on par with Speck's Tough Skin in thickness however unlike Speck's this doesn't stretch and loose its tightness. It's made out of Oakley's Unobtainium rubber, which is what put them on the charts back in the day, and feels nice. Traction is good and you wont be dropping it.
Like the Tough Skin if you do put it in your pocket, unless your pockets are absolutely huge, this will pull your pockets inside out.
Its big, yes, but its also, as my friends have said, pretty much indestructible. Some people may find it ugly but I am a huge Oakley fan so this style is perfectly in my alley.
It's $30 (same price as the Tough Skin and cheaper than the Incase Slider) and well worth it if you are looking for absolute protection and the aggressive look that Oakley offers.
On a side note... you may get made fun of, like I do, but I really don't mind.
