Sorry, asked this in the interchangable parts thread, but I don't know how often people check that... Is this correct, and vise versa then? I can get Half Jacket 2.0 lenses and they'll fit in my Flak Jackets? Is it a perfect fit, or is it loose? Or some modding needed? I looked around, and this, and an ebay auction that mentions the lenses fit both HJ 2.0 and FJs... Wondering how Violet Iridium would look in my Polished Rootbeer FJs... And the HJ 2.0 XLs are a different lens than the HJ 2.0 right? I'm wondering because the oakleysi site has different/more options for the Half Jacket 2.0s than for Flak Jackets.
