These are great for the cyclist. I can't believe how clear the lenses are. I sometimes forget I'm wearing them if I have the lighter lenses in (also a nice bonus that they come with both a darker polarized lens and a lighter/low-light lens). I have a fairly narrow face and it's sometimes hard to find sunglasses that fit, but these fit nicely because of the curvature and they are super comfortable. They rarely fog up, and when they do it's very minor. I can't speak to their durability as I haven't dropped them (knock on wood) or put them through any sort of stress yet. Unbeatable lens quality for the price, grab a pair if you find a good deal on these!
