Now that you've pointed it out, I can see that it is probably cloth, but at first impression it looks very much like plastic. And it is not clear from the video just how porous it is. Is it coated in some fashion, for example?
I would note, however, that the increased tidal volume in this head piece will be very much greater than in a face mask, and that will impact usability, especially, but not only, for people with claustrophobia.

The fabric around the edges is cloth, so I really don't think it would be any harder than breathing through a cloth face covering. I think it's an interesting hybrid between face coverings and face shields that might be used to address a variety of situations that have been discussed here recently.

Gee that would be perfect if we didn't need oxygen. Each time you exhale in that thing your breath fills the space and some leaks out round the edges. When you inhale, you breathe in mostly what you just exhaled plus a little that leaks in from the sides. The CO2 level is going to rise and I give that patient about 4 minutes before there is some heavy breathing and a complaint made familiar by activists.
Note the video says it is just for moving patients from one place to another. Wouldn't work in a NYC hospital where you typically are grown over by moss while you wait in the hall on gurney.

This was posted on the ABSA listserv, and I thought there might be some interest in this community as well given recent discussions.
All the best,
Kristi
