I recently put in an order for the Outer Foil. It reminds me of the old Oakley styling for Rx models (with legacy-inspired models like the Lizard 1 and 2 to remind us they still exist): Thin C5 material for the frames with tiny lenses (relatively speaking compared to today, anyway). I like the angular-ness of the Outer Foil, since it reminds me of the Hollowpoint 2.0, which is probably one of the preferred Oakley Rx models I've worn. - Oak
The hinge and the temple looks like a mix Crosshair 2.0 and Crosshair.
