Sorry to intrude, but when I last looked there was only one flying suit. It had trousers and a jacket. All the one piece growbags are called 'flying coveralls'. The difference between air and ground growbags is probably just in the fire retardant properties. {I am not talking cut, style, fabric etc just the name}
At ISL once two of us, in flying suits, the rest in the bar in coveralls, weer told to take our jackets off. We did.
We were resplendent in green shirts, green pully and braces on top - no rank badges as the pully does not have sliders.
Put your jackets back on we were told. no ranh badges was too casual.
