Ok, so I tried to do a search, but nothing solid came up. I'm Asian, and therefore Asian fit glasses seem to fit pretty well for me (Chainlinks at least). Now I was looking at a pair of Asian Fit Racing Jackets OO9197-xx compared to the "regular" fit OO9171-xx. So me being confused I call Oakley, they said it's the same, just the nose piece is different, and that all models, regardless of Asian/regular fit, come with the extra nose pieces for Asian/regular. (Btw, both model numbers can be found on o-reviews) What they could not answer for me, is why then, would they have two different model numbers? Why would they not just automatically include the extra pieces? (I know they come with two sets, but is one specifically for Asian fit?) So this makes me wonder, could the actual frame be different and they (call center) don't know that, and just assume they all have the "Asian fit" nose piece?
