Diego Sunglasses


Costa's most advanced sport performance sunglasses yet. Diego features an 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. With a name inspired by San Diego, a popular place to fish, Diego will stop at nothing to keep you out on the water longer whether you’re chasing Yellowtail or the mighty Bluefin.
