Thanks for that.

I was just a little surprised when you mentioned Nomex for the aviator's exposure suits.
Of course it makes sense, but why don't the mariners use it?
Boats catch fire too.

I am not a pilot but because I worked in refineries a bit I have a bit of Nomex gear.

We usually get it as coveralls, but I have a Parka, a fleece hoody and a pair of fleece track pants made out of it.

Peter Clark pointed out to me that the Nomex fleece was even more flameproof than the regular Nomex cloth.
The regular Nomex fabric is used just for the shell cloth to protect against flash fires igniting your regular clothing. The fleece is able to give a bit longer protection time.

I don't know if you know Tom Legare or Peter Clark so I will give you links to their company just in case you are curious.

This one is to Arcwear who is actually in the USA.
It has videos of flash flame testing of the garments.

I no longer work in the refineries and I am glad that Nomex never had to save me, but there were a few times it was pretty close, and I was very glad to have the PPE on.
There are still times I will wear the coveralls, like if I am working on a car or welding.

Edit:
The way I said it makes it sound like my fleece is just the lining. I didn't mean that.
The fleece I have is its own garment with no shell material.
