I have some Fast Jacket XLs, Silver with Blue Iridium and Persimmon lenses, and I'd like to buy some more lenses and customize them a bit. I've searched, but I can't seem to find the answer to these questions: Will the standard lens fit in my frames, or must I use XL lenses? I'm in Canada, and at ca.oakley.com they don't show XL replacement lenses - are these available on the US site? They list the ear sock replacements on ca.oakley.com, but when you click on them, you get a 404 error - are these also unavailable, or can you get them in the US? I travel to the US fairly frequently, and will just have them shipped to my hotel if they're available. Thanks in advance.
