Company calls these their most "advanced sport performance sunglasses yet."  "... innovative vented spring hinge system to maximize airflow and enhance fit, plus sweat management channels that wick away moisture to cool and ensure all day comfort. Diego includes flexible, strap ready temple tips, and top and side shield details to eliminate light leak. Paired with coloring enhancing polarized 580 lenses that provide 100% UV protection, Diego is the next evolution in performance sunglasses."

Measurements are as accurate as I could make them. I believe they are very close.  Clean, no scratches or blemishes. I can't wear sunglasses, so I'm listing these.

Original hard case from Costa is included.
