Just thought I'd share some additional pics of the Mainlinks. I'm very impressed with them. As far as I can tell, they're like a cross between the Jupiter Sq and the Twoface, but of course built to take more abuse and as far as I can tell, the dont have a pin in the hinges (more like the sports specific frames). So the looks of a lifestyle, but in a package that can be worn for some sports and of course outdoor activities. Even down to the Unobtanium on the nose. Anyone familiar with a Chainlink will know how they are made. But the shape is much different. I sold my Chainlink about a week ago, or I would have them in the comparison. Hopefully this helps! I think I'm going to end up with the Tungsten and Prizm Daily colorways as well. I would also bet well see replacement lens options for these as well as replacement rubbers in short time?
