I've actually got several pairs, because I use them at work, and as shooting glasses, and...and...and...
I have the foam trimmed differently on some of them, and I switch back and forth between them depending on the totality of the circumstances. The pair I'm wearing right now has most of the foam intact, and the strap attached. I've got an older pair with almost no foam, no strap, and all scratched up, that I wear to fights. I keep a pair with clear lenses for clearing buildings at night, as well as for OC or Taser use.
I prefer the standard smoke-green lenses. The polarized ones are too expensive, and the automatic adjusting ones just don't work, for a couple of reasons.
It's usually just a matter of slightly adjusting them to get them to un-fog, if they fog at all. A little more work than the Oakley Pro-M frames that I used before, but a lot more protection, too.
