all airsofters know that goggles fog up. I've been using these for about a year now, and although I still get frustrated with them, they have performed better than anything else I've tried. Airsoft allows for wire mesh masks, which completely eliminates fog, but reduces incoming light, and reduces the clarity of your vision. I can't deal with not seeing my target before they see me, so I have to use clear lenses. Like I said, I've been using these for a year. Walking around the house, I forgot that I was wearing the goggles. doing normal activities, they do not fog up at all. Also, for the first 30 minutes I'm in the field, they do not fog up at all. However, when I'm sprinting around during a game, they start fogging up after the first 30 minutes. I've also played in rainy conditions, and the fog was terrible, i had to give up, because i could not see someone that had me in his sights from 35 feet away. Recently, I took off the small amount of foam that covered up the top and bottom of the goggles, and it did not fog up after that. Of course, I haven't gone airsofting since I took off the foam, so I don't know if they'll fog up during a game.
As for the goggles, they are beautiful. They fit on my face comfortably, they don't slip off my head when I run, or drop prone. They do not have any scratches on them, and I've put them through a lot of use. They have accumulated small amounts of dust, but that's because I was too lazy to wipe them off. I use them under the acu boonie hat sold by asgi, and it works great. They barely fit into my pasgt helmet, but it's an uncomfortable fit, so I stick with the hat. I will try these goggles in a couple of games this weekend, and if they fog up, I'll try some new anti fog spray I have. If that fails, I think I'll try the hellfly glasses, also by Revision.
One last thing, I noticed that asgi also sells a fan kit to bow air through the goggles, and I have no doubt that the system would work.
wide field of vision
able to use iron sights without goggles hitting stock of gun
usually last around 30 minutes without fog
perfect clarity when clean, and pretty easy to keep clean.
fog up after 30 minutes, but I make everything fog, maybe other, drier people will have better luck
