I recently purchased a set of Flak Jackets from Amazon, they actually were from Amazon as well, not a 3rd party seller. Oakley 24-433 Matte Black, with Black Iridium XLJ Polarized lenses. Threw them on, fit great, blah blah. I strolled down to my local Oakley store and purchased some Prizm Golf XLJ lenses, and took them home. I instantly noticed when opening the package, the small size difference between the Prizm XLJ lenses (larger) and the BIP XLJ lenses (smaller). Hmmmm, I thought all XLJ lenses were the same size? Looking at Oakley's website I can actually find a pair (not my model) that are listed here: Oakley Polarized Flak Jacket XLJ | Official Oakley Store Where the measurements are as follows: Lens Width 58 mm Bridge Width 22 mm Lens Height 39 mm Temple Arm Length 133 mm ..and then another model here: Oakley Polarized Flak Jacket XLJ | Official Oakley Store Where the measurements are as follows: Lens Width 63 mm Bridge Width 14 mm Lens Height 37 mm Temple Arm Length 133 mm So..what gives? I actually like the bigger Prizm lens. I'd love to have some BIP in that size. But am I correct in my findings? Different XLJ lenses can be different sizes? Anyone ever heard of this?
