These glasses are extremely versatile and fit comfortably on my moderately thin/ medium size face. I like the retro '80s style but also appreciate the fact that they're not TOO boxy like some newer styles. The interock system works well and makes it very easy to switch out lenses on the go. The frame also seems incredibly durable (though I cannot comment on its long-term durability just yet). Overall, they are a great pair of shades for the price.
