I'm selling a pair of Black Iridium XLJ's. I got a pair of Deep Water PRIZM XZlJ lenses, and now I wear my Flaks all the time. Colors are so vibrant with the Deep Water lenses, and the Polarization really makes them the perfect bright day shades. I just have no use for the Black Iridium lenses, and they're just brand new. I think I should keep them, because I think XLJ lenses may become hard to come by with the Flak 2.0's taking over.
