I bought a pair of Sly's and love the look and they are comfortable BUT, just like many others have said they fog up quickly and completely - not just in a little spot on the lense but the whole lense to the extent that I had to take myself out of the game I was playing and literally stumble back to the safe zone cos I couldn't see for toffee!!! They are also not the best for being able to hear your teammates. Going to try some Pro Flex or Grills as I think the Sly's have turned out to be a costly mistake.
