These masks allow me to communicate better under the constraint of wearing them. I have noticed people are visibly friendlier when they can actually see your face and smile. They do need so.e sort of defogger treatment, I used dish soap, let it dry then rub off with a clean towel. The cold weather may pose a challenge with the temperature fluctuations from outside to in.

It works well after you use a defogger technique of your choice. I'm pleased so far.
