The clarity is supurb, as expected. Weight not bad at all for 580g.I really like the slightly heavier 580g when driving on the water. Costa's are the only sunglasses that have taken the rides over 80+mph, panning left-right watching for things you really don't want to see while driving 85-90+mph in a bass boat, yet no fear of the glasses flying off.Oakley's never made over 70mph with any confidence. Guess that's why Oakley now owns Costa.Glasses ram small do having to return them. Perfect for a lady Unfortunately I had brought them hoping that they would fit my husband. I love Costa Del Mar. I live in Murrels Inlet SC Everyone here swears by them I will recommend this site.Frame is not good materialMy husband and I had been looking for a new pair of sunglasses for him and finally landed on these Costa Tico with the navy frame from all our sunglasses-trying-on sessions. They have been priced at $250 everywhere I have seen them, so I grabbed this when I saw it. They are real glass lenses (580P is plastic lenses and 580 or 580G are glass lenses). Glass is a little heavier but they are clearer than the plastic lenses, so that is what he wanted. He loves them!!Unquestionably the best sunglasses that you can buy at any price getting them on clearance sale 65% off only makes it that much sweeterThese were my 1st pair of “expensive” polarized glasses at $154. I have always heard good things about Costa glasses but my pair are certainly disappointing. I bought them in January and live in the Midwest so certainly did not use them much. Unfortunately in June, just when I need them most they fail. The rubber on the inside of the arm separated from the arm, on both sides. You can see from the picture this is not a structural problem, but a problem with the way the rubber is attached to the arm. The view from the lenses is very good but I can’t really use the glasses like this. Tied to speak to the seller but they just Lee me off. The dealer has a 5 day defect policy, pretty weak if you have a good product. Apparently they don’t stand behind your products. There is no way the rubber should separate from the arm with such little use.Fit perfect for an average size noggin. Love the coverage !!! Perfect styleYes, u can get costas for half price on amazon!These are same quality as other pr I haveQuita muy bien los reflejos del sol en el mar
