Does anyone know of a manufacturer that makes a mask that doesn't fog? I thought I read about one once in a magazine but it was long ago. Maybe I'm just being too hopeful.

I don't think such a thing exists - buy anti-fog drops.
Actually there are quite a few. But...you do need to spit in each before each use to activate the secret anti-fogging ingredient.

I actually believe the FFM masks have there own fog prevention on the mask also as the air come into the mask it acts as defog. atleast thats what i have been told when asked..
Creating a semi-permanent surface that allows a thin sheet of water to seamlessly and uniformly adhere would probably make you rich. Pinlock which is the best antifog product I have ever used on land is a water absorbing barrier that creates an air seal between it and a visor. I don't know what would happen if it were submerged though.
There also might be some perfectly formed surface that would work but if it exists I cannot imagine it would be inexpensive.

Yep FFM do not fog because of the air that circulates in the mask. I'm preyy sure they are the only masks that don't fog without spit or defog.
Never used a FFM but almost any surface will fog if there is moisture and heat/cold differential. Guess it would be the dry air coming out of the tank sucking up the moisture.
