Breath guard stops fogging and noise

[erix]

Ya wanna know whats stops fogging?
Spend $35-50 on a fog city pro visor insert (clear film that sticks to the inside of your visor).
I'd known about these for quite a while, but never got around to getting one.

I could NOT fog it. That was TRYING to fog the thing. Close all my vents, close the visor. Pull me head down so the base of the helmet is blocked by my jacket. Huff and puff all I liked (at night in the cold) and it would not fog one single bit.

Totally recommend.

Yep, it stops fog as well, however, one of my mate got one piece of this kind insert from mt mtc few months eailer, it works well at begining, but, i dont know if its my lazy mate didnt do any mantaince or cleaning for it. it becomes unclear and it has devloped a problem of "aging" like any plastic does...

Can they be fitted to any full-face helmet?

And 'not so safe and comfortable' as what??

No, I brought the breathguard specificly desige for HJC CL-14, I dont think it will fitted in any other brand. but I did saw some other brands have their own breathguard.

as you cant hear anything(like a car) near you, which MAY put you in danger situation. Anyway, Its just my personal perfrence, while the breath guard solved the problem of fog and as bonus it reduced the noise level at the same time. and it cost as the same as an anti-fog film insert. ($45 if I remember right)

Oh, right! anther bonus is the hygiene factor. when you dont know how to refuse someone borrowing your helmet. take the breathguard off, and put it back on when they return.
