There are anti-fogging sprays available - a spray is good for a few days. (Of course this is a worse solution than making that seal air-tight)

  Where does the water vapor go? It condenses into droplets then skates back and forth along the bottom centimeter of plexiglass? That would be disgusting to look at. Or maybe it absorbs into the cloth hood/neck piece? That way when the user pulls it up off their head they get to squeegee their face with their own cold saliva. Sounds awesome!

    It just forms a thin film instead of forming larger droplets. It’s no less or more disgusting than having fog in the first place.
