I have a pair of Fast Jacket sunglasses that I would really like to get some new lenses for. I read an article that Fast Jacket and Fast Jacket XL are the same frames and the lenses are interchangeable. I bought a a couple sets of Fast Jacket XL lenses and a set of the rubber replaceable parts from Amazon. None of the parts fit my frames. The Fast Jacket XL lenses are smaller and fall out of the frames. Does anyone know where I can find a set of Fast Jacket lenses? I posted a few pics of the Fast Jacket XL Lens sitting on top of my original Fast Jacket Lens. As you can see the not only is the lens smaller but it doesn't even have the same shape. I just want a decent set of lenses so I can actually wear the glasses again.
