Dumb Question (and I did unsuccessfully try the seach feature...). I just got a cool pair of custom Halfjacket 2.0s with polarized G30s in them. First pair of Oakleys, and the best glasses I've ever worn. I want to get a couple of lenses to swap out for when I go fishing, looking at the Shallow Water and Deep Water Prizms... I see on the oakley homepage that they have my Halfjacket 2.0 lenses in Shallow Water Prizm, but the Deep Water lenses only comes in Halfjacket 2.0 XL... The Dumb Question being, will the XLs fit my 2.0 frames? It is my understanding that the 2.0 XLs only have a different shape at the bottom of the lens, the top snaps right into the 2.0 frame.
