I have been knee deep in researching escape hoods which for us, is an EDC item since we work in an ammonia plant, here is the link to the compact one that I found:

Since these mask are made in Israel and I work in Egypt, we were unable to use them and ended up with Draegers which are bulkier and most expensive.
I don’t know if anyone else has had expierence with these. Besides ammonia escape, they can also be used for escape from smoke (not oxygen deficent) environmentsa and other gases.
The Durham one is extremely compact and I carry it on an outside MOLLE pouch on my T.H.E. Pack I use.
Anybody else done any research on these?
