The Oakley Sielo (OO9288) pieces together everyday elegance with performance comfort. Uber-soft and rounded, the aviator shape gives off a most laid-back vibe without lacking in subtle refinement, so equally great with casual and dressed-up looks. The lightweight BiO-Matter in the front of the frame provides full support to the strong and solid C-5 metal temples. Unobtainium® nose pads and earsocks secure these glasses in place while keeping them comfortable, and the enhanced color and contrast of Prizm™ or Prizm™ Polarized lenses provide crisp, vibrant, and true vision in bright light.
