I'm a pilot and I consider these the best sunglasses I have ever used. The S-Flex design allows the arms to sit close to the head and comfortably under a headset. The lens size/shape keeps the frames out of the field of vision. Importantly, for pilots, these sunglasses are not polarized... so there's no issue with the screens of some glass cockpits. They also have photochromatic lenses that change darkness slightly and a non-reflective surface that keep your eyes comfortable in all lighting conditions. I can't praise these sunglasses enough - that's why I own two pairs.
And, of course, pilots are all about looking good - and these look great :-)
Pros: Quality, desgn, comfort, looks
