The suit in question.

This variety has the tyvek layer, which is hot enough, but also a poly layer for liquid protection, so it doesn’t even breathe. I use the tyvek ones, no poly layer normally, all the time, and they are, as you say, really hot, especially if you’re doing anything physical.
Add no AC in Africa and appropriate respiratory protection, and I don’t see how doctors can work in this gear at all.

One Dr. there wrote about this...I recall him saying they had to limit the time in these suites otherwise they were passing out.
But for surgery hours they had no choice but to remove long enough to breath.
