Oakley announced that Sienna Miller is wearing Oakley Nanowire 3.0 sunglasses in the movie G.I. Joe The Rise of Cobra. The lenses have the Path shape and VR28 color, and have either a 'True Blue' or 'Metallic blue' frame. On Oakley.com you can customize your Oakley's to this exact combination.

Sienna Miller plays the Baroness (Ana Lewis) in this action packed GI Joe movie, where the bad guy uses nanotechnology to build an army of soldiers to rule the world. Maybe the same nanotechnology that Oakley uses to create Sienna Miller's cool Nanowire shades.

The Nanowires are not cheap, but have polarized lenses and are extremely light. They are available in the following colors: Polished Black/Black Iridium lenses (12-919)
Brown Chrome/VR28 Black Iridium lenses (12-920)
Olive Chrome/Tungsten Iridium lenses (12-921)

Formule 1 race driver Lewis Hamilton has also been spotted wearing these glasses.
