Pros: Works really, really well.
Cons: Once applied, you can't touch it. Not exactly cheap.
For those of you who haven't read my other review on the itech 920 hockey face shield, I bought a visor cage combo about two months ago but had a great deal of problem with fogging. People gave me all sorts of advice on how to keep my visor clear including using toothpaste, dishwasher fluid, shampoo, windex, etc... but none of them worked very well. I went and tried various anti-fog products including the itech spray, fogzero, Smith no-fog cloth, and Fogtech. If you think all the anti-fog treatments are the same, keep reading.
Well, Fogtech was my last stop in terms of trying anti-fog treatments, and I wish it was my first. But if I had used Fogtech first, you wouldn't be seeing my other reviews because I would have stopped here. Suffice it to say, THIS IS THE ANSWER TO ANTI-FOG!!!
Fogtech comes in wipes or a bottle. I opted for the bottle because the wipes would have gotten really expensive over time. The bottle is small but supposedly good for forty applications. It also comes with two soft wipe pads that can be used on delicate glasses or heavy duty goggles (hockey shield in my case).
Application is fairly easy but takes getting used to. The first thing to do is squeeze enough liquid onto the pad so there is a wet spot the size of a nickel. This isn't very much, but you can't get away with using only a few drops. And here's the hard part. When wiping over your visor, make sure you don't go over the same part twice. Okay, so it's not that hard, but when you come from using anti-fogging products that require you to rub a lot it is a hard habit to break. If you do end up going over the same spot, there usually is a bit of smearing or a piece of fuzz from the cloth that will stick to the visor. Not the end of the world but kind of annoying. Now you need to let the stuff dry for sixty seconds. Fogtech literally forms a coating that prevents fog from forming on your shield. The problem is, once it sets you cannot touch it or it will smear. But really, if your shield doesn't fog up, there is no reason to touch it. Just be careful not to get sweat all over, and you'll be fine.
Although people keep telling me the way to keep fog off your shield is to keep moving, I have found this to be a great fallacy. The problem is even when going at high speeds, the circulation in the shield is not good enough to dissipate all that moisture. In fact, the harder I skated, the harder I breathed, and the more fog built on my visor. I don't plan to be lazy on the ice just because my anti-fogging doesn't work.
So enter Fogtech. I was apprehensive at first being disappointed with other anti-fogging products. Then I stepped out onto the ice and started playing. After thirty minutes of grueling skating, there wasn't a spec of fog. Then forty minutes passed, fifty... I ended up skating an hour and a half with little to no signs of fog. I thought this might have been a fluke and tried it again the next day. I washed the original film out with water, then applied a new coat. This time I skated for about an hour semi-hard. Amazingly, there still was no fog that built up. I am going to try again without applying a new coat to see how long one application will last. Nevertheless, Fogtech has become my savior as far as visors are concerned. I was almost ready to give up and go back to the cage.
At $15.00 a bottle, it ain't cheap but well worth it. From now on, when anybody tells me a visor is worthless because of fogging, I'll tell them about Fogtech.
Update: I decided to skate a second time without applying a new coating. At first, a tiny bit of fog built up right where my nose breathed directly on the shield. I wiped the fog off with a soft cloth even though I knew it might smear. However, this time it didn't smear, I am guessing because the coating had a few days to dry, Skated about an hour after wiping off and still no fog formed. This stuff works ridiculously well.
