Before you put the boat in the water, put on the Costa Del Mar Harpoon Polarized Sunglasses equipped with the Costa 580P lenses, so you don’t get blinded by reflecting waves and run the boat aground. Enhance your vision with the Harpoon’s 100% UV-ray blocking glass lenses, which not only cut out the blinding yellow and white light, but boost the rest of the color spectrum so the water, the beach, and the road appear in high definition. The medium-sized, sleek nylon frame wraps around a man or woman boat captain’s face thanks to the 8-base lens curvature, while the nose and temple pads hold the Harpoon in place while checking to see if your fishing line is caught under the boat. Once you get a catch, the strong stainless steel spring hinges ensure that they won’t break if you get smacked in the face by a bass and the Harpoon hits the deck.
