I don't have a Vader suit, only leathers and a full face helmet that would make me sweat like a pig!
Trying to work on something in a monkey suit, come on guys be nice LOL! That would be miserable.
I retired from working in nomex suits(flash fire resistance) they were too hot makes you sweat, I though I'd just as soon burn up a wear them. Luckily I never got into a flash fire, I did get burned at a fire fighting school once that made me mad as yell, the training got too real. Getting toasted hurts! I said some very nasty words that day and so did the guys that got burned with me. We had to fly from Oklahoma back to Va. looking like over cooked bacon.
