Do they really help? Either ones that come built in or ones added.

I've had a few issues with my mask fogging, not near as much as some older ones I've used. I'm going to try some of the no-fog tips on here before I either buy a fan or another mask. Also would the fan help with face sweat?

FANZ are the best I have used. The JT's and Dye's suck and are loud. Here's a link:

FANZ KITS & PARTS

They have ready made kits and kits that you can make yourself. They will work with any mask to

Basically, those FANZ are probably your best bet. Technically, you could buy it all at Radio Shack, because it is a small computer fan connected to a 9 volt and an on/off switch. But it is cheaper to buy it at the FANZ website.

My goggles have the JT Spectra frame with thermal lens. I have never had an issue with my lens fogging up, except for when the thermal layer separated from the lens. Main thing I have to worry about is my glasses fogging up. a combination of anti-fog spray and the JT Vortex II fan keeps my glasses fog free in all but the worst conditions.

here's a link to my thread at milsim empire:
MilSim Empire • View topic - Devlin's mask

Awesome replies. I was honestly considering buying a JT fan that is really small and mounts on top of your forehead for $20. I think the FANZ/DIY with something similar to Devlin's setup would work better since I can just customize it any way I need to.

And like Dark Shadow Hunter I wear glasses and sometimes I have a hard time finding a mask that fits well with them. I haven't had them fog up too often but if I don't have my mask on in a certain way I tend to get moisture on them from my exhaling not exhausting from the mask properly. Which I think starts to led to my mask lens fogging not to mention my head getting hot and sweating.

I used the JT mask fans, both versions. They lasted a few outings, but were always loud. I've had the Fanz for a year or so and they work fine. The fanz also work 100 times better than the JT's

i think i going to get a set from fanZ but instead of a on/off button ill use oe that u hold in to turn it on

When ever I go in for an eye exam to get new glasses I always go for a smaller wire frame. So far the only goggles I have had issues with were the ones with the JT Elite frames. They always wanted to keep my glasses when I took them off.

I run a single FANZ kit in two of my masks and they work like a charm. I have thermal lenses and before the Fanz, I would still fog. I no longer fog and am able to see my targets
