The first pair of Oakley sunglasses I ever had were Frogskins, over the past years we have seen the Frogskin come back as a limited edition. The Jupiter on the other hand are quite similar but considerably more sturdy than the Frogskin. The frame has a bit more curve to fit the face better. Coming in many colors for your own style and even Polarized lenses. I like the retro look as many others do.
