Re: Masks that are actually anti fog

I've never had any issue with a mask fogging after toothpasting it before the first dive and spit every time right before I put it on to go in. As I understand it saliva is slightly alkaline which affects the surface tension of the moisture and prevents water droplets from forming on the glass. That or I could just be completely talking out of my ass.
