Well I haven't tried it yet in real life because I haven't used the helmet yet. Fits perfectly in my Gmax GM54S helmet and seems to keep the shield from fogging, but I haven't tried it on my snowmobile yet. Conforms nicely to my face for a snug feel. Not great with the modular helmet since the velcro has to be peeled every time you lift the face which tears up the cheek pads a little, but I haven't found a better fog guard for this helmet.

This unit is well made. easy to install. and appears to work. NOW for some really cold weather and Snow!
This breath box snaps right in easily and fits well. Face shield still fogs slightly on cold days, but not nearly as bad as without it.
