Oakley Probation Sunglasses: The original Inmate® broke fashion rules. The Oakley Probation Sunglasses was their idea of a repeat offender. Instead of separate lenses, it has a single contour of pure PLUTONITE® lens material. The sculptural frame takes advantage of C-5™, a lightweight alloy of five metal compounds. If you’ve never experienced the comfort of the straight-stem designs, you need to ditch ordinary shades that hook your ears and fit with unbalanced pressure points. The Oakley Probation Sunglasses are engineered for all-day comfort, and when the heat is on, the UNOBTAINIUM® sleeves on the stems are there to increase grip with moisture.
