Our 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, one of our favorite places to fish, Diego will stop at nothing to keep you out on the water longer whether you’re chasing Yellowtail or the mighty Bluefin.

  • Sunglasses that are worth the money!
I am on my third pair of Costa Del Mar sunglasses in last six years. This is my new favorite pair. First pair were polycarbonate 580P, second pair I upgraded to glass lenses and so glad I did! My previous pair were absolutely awesome, until I dropped them. They were in the case, and it was about midnight and I was on my electric scooter and never heard them fall. Found them next morning and pretty much wanted to cry. Utterly destroyed. These Diego’s, are actually better covering from glares at all angles, stay on face more snug, and I caught em on sale!!! ... show more

  • Can’t go wrong with Costas
Color: Matte Black/Sunrise Silver Mirrored Pola... Lens Width: 62 Millimeters
These lowlight glasses are outstanding for early morning and late day fishing and hunting. In low light conditions they’re outstanding. They will fit multiple sized faces, but tend to be better on larger faced individuals.
