I bought a pair at Diamond Dogs (last pair on the stand) and just wanted to say these are top notch. They fit like a glove and I only had one instance where they did fog slightly. First thing Sunday in the AM inside building 3. The humidity was horrid that morning especially with all the windows closed. Other than that one episode I never had to wipe.
The clear lens were perfect for the night op as well. Simple to change out. I recommend these to anyone looking for a good pair of protective eye wear.
