HAMLIN is rated 4.7 out of 5 by 33.
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 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.
