Tough design and great style.

The Costa Del Mar Harpoon Polarized Sunglasses offer durability, comfort, and classic styling to your days on the lake or at the beach. The Costa 580 polarized glass lenses resist scratching, enhance clarity, and block glare off the water while you look out for the big one.

Perfect for Tropics Fly Fishing

  • Familiarity: I've put it through the wringer

The Costa de Mar glasses are the preferred brand of saltwater fly fishing guides everywhere. The G designation means glass lenses and the P designation means plastic lenses. Glass is heavier and might slide down your nose easier but is clearer. Plastic lenses are lighter but are less scratch resistant and tend to take much more abrasion damage in salt water conditions. Get the glass lenses if you can afford them.

If you are in the tropics, get the mirror lenses to reflect more sunlight and take in better angles for long distance sight casting. I have a blue mirror for offshore fly fishing and copper lenses for lower light sight fishing conditions.

Hey Stephen,

In general, the mirrored lenses will reflect more light away from your eyes and allow you to see better in bright conditions.

Will you guys ever get these in with a green mirror lens?

Hey Jason,

It's not looking like it. Sorry for the inconvenience.

Awesome Glasses

    Got these for my girlfriend and they are excellent glasses. 580 lenses are so comfortable and easy on the eyes, they are addicting. Great craftsmanship, no complaints, would buy again.

    Best Shades Ever

      I've had the tortoise with 580 amber lenses for 6 years now and they are my only pair that I wear. Whether it be on the water or hiking, you can't beat these sunglasses.


        By far the best sunglasses I have EVER worn. I have the Green Mirror 580 lenses and they are perfect. If it is super bright outside or overcast and gloomy these lenses give the perfect view. Anytime someone tries them on they are blown away by what they see. Do not hesitate to buy these!!

        The best glasses you will ever own!

          I own 3 pairs of these glasses. I have 2 pairs with the 400 and 1 with the 580 lenses. I basically live either on the water or at the beach 6 months out of the year. I am very sensitive to bright light. The 580 lense is the way to go.. they are crystal clear and dont scratch. These glasses are the bomb! They are worth every penny.

          How about this for a bonus. My first pair were worn out. I sent them back to Cosa repair center and they completly rebuilt the glasses and they were just like new... total cost $9.99.. I had them refresh my second pari as well.

          Great company - great product -great value!

          Put them in your shopping cart..stop thinking about it...
