Our most advanced sport performance sunglasses yet. Diego features an innovative and patented 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. In addition, Diego includes flexible, keep-ready temple tips and top and side shield details to reduce the light leak. Paired with colouring-enhancing, polarized 580® lenses, Diego is the next evolution in performance. With a name inspired by San Diego, one of our favourite places to fish, Diego will stop at nothing to help keep you out on the water longer, whether you’re chasing yellowtail or the mighty bluefin.
