Rated 5 out of 5 by from These glasses saved my right eye from disaster!! These are the best glasses I have ever owned. Perfect clarity, durability and ruggedness. I have used these glasses everyday for two years on the farm, day in and day out. Last week, I was fly-fishing in Alaska when my fly-line became snagged on a rock in the river. I went to break the leader and just then, the line came free and was flying at my face at Mach 10!! The one ounce lead weight hit me directly in the right lens of my Costas. Although the lens had suffered a direct hit from a one ounce lead weight, there was only a small crack in the lens. There is no question in my mind that I would have lost my eye that day. No question what so ever. I am getting them repaired, which is far more than what could have been done for my eye had I not been wearing these glasses. I cant thank Costa Del Mar enough. Thank You to the folks at Costa for making a superior product.

Rated 5 out of 5 by from Very comfortable I have always had a nightmare when sunglass shopping due to me having a huge cranium. Most sunglasses are too small for my head, face, or both. But the Costa Del Mar Hamlin's I just got feel great and are actually wide enough to cover my face from one side to the other. They have good clarity, and they are very comfortable to wear for any length of time

Rated 5 out of 5 by from Amazing product ! I love my Costa's the best sun glasses I've ever owned! I use them every day at work or just enjoying a nice day out. I've gotten quite a few complements about them, the only negative thing I can say is I wish there was a size XXL offered my glasses are just a tad to small but over all I love them! Perfect for South Texas/Gulf coast areas or any where.

Rated 4 out of 5 by from Very nice but XL small for large heads. I bought these a month ago and ordered extra large. Not sure that is what was sent because box not marked? They fit a little snug for a large head. I wear a 7 5/8 hat so if these are extra large, they are a little tight. I would suggest buying them at a retailer perhaps so you can try them on.

Rated 5 out of 5 by from Best Glasses I've ever had! I used to be an exclusive Oakley guy, but after a friend at work showed me her Costa glasses I was hooked. The XL frames fit my head perfectly, and the 580G lenses are so clear. I still tell my wife how colors pop in these lenses and I'm going to be buying Costa glasses forever. If you're on the fence about spending money on these, take it from me, you truly get what you pay for. You'll love them as much as I do.

Rated 4 out of 5 by from Too small I just got these today and they are unfortunately too small. I've had the permits before and they were almost too big, so I assumed that any extra large pair would fit, I was wrong. Great sunglasses just too small. They should be sold as large not extra large.

Rated 5 out of 5 by from bought 2 pairs!! My boyfriend and I both got the same pair!! love them! He opted for the glass lenses in his over the plastic which makes them quite a bit heavier (to be expected) other then that, they are amazing!
