These are my second pair of zero's. I had a pair of the last version, and based on my love of those I bought these sight unseen.
Overall, I like the glasses very much. They have almost no weight at all. The nose piece and ear pieces hold on very well no matter how much sweat comes off your head. The lenses are Oakley clear, no distortion at all.
The only issue I have is the arms are rather thick, which is fine for style, but can impede peripheral vision a bit.
