I found the photo of this hood on Facebook, but the author did not say where it is from, what the hood is, if he owns it, etc. So I assume that the photo was also found on the Internet.
Anyway, here’s why I reposted it. First of all the hood is anatomically shaped. Second, it’s got nose tubes with quite a big internal diameter, what should (theoretically) keep the holes at the correct place and supply enough oxygen. The tubes also will not allow you to see through the nose holes (sometimes it is possible).
Then, I wonder if there is a built-in gag. It looks like the person inside the hood is quite tightly gagged.
If anybody knows where such hood can be bought – please let me know.
