It would have to be pretty minimalist--lots of what I have in my BOB doesn't readily fit in pockets.Flight suit sized to fit over your civvies with the pockets loaded with BOB contents. Store this in a nearly empty backpack and stuff it with items that are always in your truck (mission essentials) and move!
Did not enjoy nomex CVC coveralls at all back when I had to wear them -- even the aviation crowd has shifted towards two piece FR uniforms for the better practicality they offer. (Plus, I think at the big picture logistics level it's easier to get a properly fitting uniform when you have two halves to mix and match versus a single garment.)I had thought about tankers coveralls once.
But, have you ever taken a dump when wearing coveralls?
