I'm a pilot and fly in it regularly. They are also great for driving. A few things worth mentioning. The lens is amazing. I love sunglasses that are not very dark. I like when they're light enough that I can see the screens while still blocking out the sun enough. I also love them because I can wear them on cloudy days and their transparency is excellent. The only drawback is that I had problems with the Serengeti and its quality. I've had several different pairs of sunglasses from them and almost all of them had screws sticking out around the lens all the time.
