i have 2 half, 2 full face, and 2 motocross helmets.

i'm not a big fan of the half helmets. especially riding a sports bike :wink: . i use my motocross helmets for drag racing and autoXing. my 2 full face helmets i use riding my bike.

anyway, when i use my full face helmets i have to leave the shield open a tad bit. dew to my breath fogging up the shield. i would like to keep my shield closed at all times. since i've had things fly in my helmet dew to it being opened :evil: . i even have the vents opened on the helmets. and i still get fogging. i've tried that anti-fog spray stuff. didn't really work that well.

so is there something i can buy to stop the fogging?
i was looking at some full face helmets online. and i notice some have some kind of mouth and nose guard. where it goes over your nose. i'm guessing this would block my breath from fogging on my shield!?! now can i just buy that peice and put it in my helmets? or do i need to buy a helmet that already has one in it?

or is there a helmet out there designed for just my problem. that i need to look into buying?

thanks for the help.

My Sy-Max has that little 'breath-guard'.. much more effective than helmets I've had that didn't have one, but it'll still fog a tad just above it, but only when stopped at a light (no air moving through the vents, ya know). Usually just cracking the shield a notch alleviates it, and I can close it back fully after I take off again.

This has been covered in other threads, and I don't recall anyone coming up with a definitive cure. And while I love Rain-X, their anti-fog stuff specifically says on the label its not for plastics.

I think EVERYONE has this problem when they start riding (you did get your bike recently right)? The fogging usually occurrs when the air is cold outside. In order to prevent fogging you need to try and breathe even and downward to keep the moisture form hitting the visor. Normal temperatures it isn't much of a big issue. I don't think it's the helmet; I think its just something you need to get used to. I used to have the same problem and then one day it stopped.

BTW, I am sorry if you HAVE been riding for long time. I have just heard the same question before and resolved in the same manner as I explained.

I have a Shoei lid with a pin-lock visor - there are two visors, with air between them. This prevents most fogging, since the air between the visors acts as an insulator.

The problem is that they are f***ing expensive - the visor plus the pinlock liner are about $70 ...

I read just the other day that you can put a little shaving cream on the inside of the shield and buff it out, like a wax. Supposedly (I haven't tried it), this'll keep the foggies down. If you try it, let me know.

Folks'll tell me I'm screwing up, but I use Rain-X and Rain-X Anti-Fog on my visors. The label plainly says to use it only on glass, but I have yet to see any negative effects. I have read posts before, however, where people claim that the Rain-X turned their plastic shield cloudy. That hasn't happened to me (yet). If it does, I'll buy a new visor.

a fogged shield just measn you are full of hot air!! haha

seriously though, i rode with my friend's wife's full face shield when riding for my first time this past weekend....(no mouth guard, open on the bottom) and if you keep breathing through your nose (like normal) this doesnt happen at all. when we sotpped at lights i would lift it up one or two clicks to talk.

i guess a couple factors must be considered here though. it was about 75 degrees here in tampa...and sitting more upright on a cruiserprobably keeps the fogging down with a lot of air coming up into your chest. i know when she wears her helmet sitting on the back she gets some fog, especially in the cooler night air.

Some shields come pre-treated with an anti-fog chemical. Check with the manufacturer of your helmet to see if they sell them. Mine works great.

I have personally went to a store and breathed on the inside of the helmets I linked to with the intention of fogging it. It didn't fog. In addition it does come with a breath deflector like the one you spoke of. I want one of these helmets so if you take this route lemme know how it handles high velocities =].

I wouldn't use a product meant for glass on plastic. They probably say not to put it on plastice maybe because it changes the integrity of the material. Might be worth risking for you but my rain-x hasn't touched the helmet. Then again I've been using windex on my helmet before reading that it shouldn't go on plastic. So I guess I'm already fvcked if a large rock finds my face shield.

Not really suprising ... you need to have a temperature difference between inside and outside for it to fog easily. I can ride with my lid closed in summer - no fogging problems whatsoever.

As soon as it gets cooler (in Spring or Fall), or when it's raining, there is that damn internal fog again. It's like the cold Coke can that you put on the table - when you take it out of the 'fridge, it's dry, because there is no big temperature difference between the Coke and the air. When you put it on the table for a while, the Coke is still cold, but the outside air is warmer, so water condenses on the outside of the can.

When you put a warm plate, covered with alu-foil into the refridgerator, after a while, you have condensation on the inside of the foil. Same principle - the condensation forms where there is a temperature difference.
