What masks are Adam and Jamie wearing?

Those are respirators. They come in different ratings, here is a link to the 3M 7500 series.
Here is another link. The little hoo-yas on the side hold cartridges that you have to replace periodically.

I’m actually looking fot the clear thing that is covering their faces.

@XOIIO That is also part of the respirator. You can buy one from either link.

Ah ok thanks.

Those are common. I have one for when I work in crawlspaces. I use this one.

@johnpowell Thanks! That looks wicked awesome! Good price too!
