HARPOON is rated 5.0 out of 5 by 3.
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 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!
