Rated 5 out of 5 by from Used for a month.... Purchased the Harpoon sunglasses here on the CostaDelMar website and was delivered within 3-4 days and came with case... No cleaning cloth which I would overlook....The sunglasses function great with the Copper glass lenses. I might buy another pair with the Green Mirror in the near future. The polarized lenses perform great and one thing that so many other do is I can look at my ipad or iphone with the protective Zagg Shield... so many sunglasses will prevent you to see the screen. But they work great to see under the water and great for everyday use!

Rated 5 out of 5 by from Good Equipment I've been wearing Costas since 1993. My Harpoons have the green mirrored glass lenses. I wear them when fishing coastal flats, flyfishing mountain freestone streams, bird hunting, driving, and general use. They fit perfectly and do not fog. They greatly improve visibility of stuff (fish) below the surface, and they also improve contrast of hazy sky, to gauge if coastal clouds are building. Some consider the Harpoon frame style to be old school from a fashion standpoint but rest assured they are good, vital equipment.

Rated 5 out of 5 by from Awesome Buy I have been wearing Costa Sunglasses now for over 17 years and refuse to switch. The lens are extremely clear and the performance is the best. Ordering online was simple and the order was on time.

Rated 5 out of 5 by from Indestructible! I bought these glasses somewhere around 4 years ago they've fished flats,offshore, rivers,ponds and lakes these have been on my face so much I've just recently noticed to nose piece rubber has conformed to my nose. They've been on the beach, in the tackle box, in truck beds and trunks of cars and not one single solitary scratch on my glass lease I'm getting ready to buy my next pair of costas just because I want the green tint as an option. I love these glasses and never never owned another high pair of glasses that can even touch the craftsmanship of these glasses

Rated 5 out of 5 by from great clarity This purchase is my 5th pair of Costa's. All have the copper lenses. I find the copper to be the best choice for me as a fishing guide. They give me good vision into the water all day long. When not fishing I find them to still be easy on the eyes and provide clear crisp colors. Everyone who tries them on can't believe the clarity. I have a different pair for different situations. I highly recommend these glasses or any of the Costa models. You won't be disappointed.

Rated 5 out of 5 by from Best sunglasses I've owned I purchased my first pair of Harpoon sunglasses with black frames and black plastic lenses in 2007. I've used them for all sorts of outdoor activities including hunting and fishing. I've since purchased another black frame with 580G blue lenses and the tortoise frames with 580P green lenses. I can't go anywhere without them.

Rated 5 out of 5 by from Stylish Shades I bought these while at our home in St Thomas USVI and they worked wonderfully for the bright sun and water. When we returned to our permanent residence in PA we had a different brightness to deal with - snow. Again these shades worked perfectly. Best part - they look cute! Go for the glass upgrade its totally worth it!
