I've purchased both the J+S Premium Military Style Classic Aviator Sunglasses and the regular J+S Premium Ultra Sleek, Military Style, Sports Aviator Sunglasses. The classics are hands down better made in my opinion. I thought it would be helpful to others to compare the differences. The lenses are identical. They both are darker than most sunglasses and excellent optical quality. The frames however are very different. The classic aviators have a really nice finish. The classic aviator  temple pieces have a softer covering at the end and the temple pieces are bendable to adjust fit. However, the temple pieces on the cheaper regular aviator are rigid (it seemed that they would break if I tried to bend them) and look much cheaper. The J+S classic aviators are just much better in quality and are much more comfortable than the J+S regular aviator cheaper glasses. I'd highly recommend spending just a little more and getting the J+S classic aviators over the J+S Premium Ultra Sleek, Military Style, Sports Aviator Sunglasses
