Classic aviators with a titanium frame is what these sunglasses are all about. The titanium frame material keeps these glasses light and yet surprisingly strong, given the thinness of the temples. The polarization on the lenses is very nice and of high quality, however it is of the 'P3' (polycarbonate) variety and not the better 'P3Plus' (glass + better contrast) variety. As an owner of two of the 'P3Plus' lenses, the differences are subtle but unmistakable - greater sharpness and definition. The quality of the lenses in these are not bad by any means though and the lenses serve extremely well under a large variety of situations because of the soft gradient. At the same time, the soft gradient isn't the best for days with near constant direct sunlight - I prefer my solid brown polarized TECH Aviators on those days. In the end, these are an extremely good pair to own for many occasions.
