I have a pair of bugs, I couldnt get use to them. I might not of used them enough. My ground guys would laugh at me when I had them on I went back to the glasses.
I wear the wrap around "Artic" model by MSA. Seems to be the only kind that fit and stay on my bald head. I find having them in sweat spot on the bridge of my nose helps alot with the fogging. And as dumb as it sounds, keeping the eyebrows from getting to bushy and blocking air flow. LOL
