Just picked up a pair for myself, did some heavy exercise with them on. Zero white-out or pale fogging, no issues until about half an hour to 45 minutes in, when there was enough moisture condensation to start to run down the inside in rivulets, blurring vision. A quick wipe with the cleaning cloth and everything was crystal clear again.

I'm usually don't have problems with fogging, but I have to say the Exoshield anti-fog coating seems to work very well. It seems to perform better than my Bolle T-800s even with all the ventilation. My Bolles currently have a Guarder lens, so the original Bolle lenses may have been better, but comparing the Guarder lens with major ventilation on the T-800s to the Exoshield with very little ventilation, the Exoshield comes out ahead for me.
