Tinfoil from Oakley is a half rim sunglass that forms part of their Hollowpoint collection of mens glasses. Oakley have been clever with sculpturing of the metal frame, it thins out as it heads from the top to the bottom. Pretty neat really and gives a nice contrast to its full framed brother the Tincan.
A great design feature of the Tinfoil (and Tincan) is the screwless hinge system in place, which means no more lost screws! Its a crazy bit of engineering to produce a tiny hubless hinge system that runs so smooth. Their ever enduring unobtanium is in place on the ear socks, working with you to keep the sunnies in place whatever you are up to and there's adjustable nose pads at the bridge so you can adjust the way they fit for some additional comfort.
Plutonite lenses, High Definition Optics, Three-Point Fit and other other great Oakley technologies are in place too.
