I was a genuine 'only for prats' sort of guy until I started to fly the Tiger Moth and Chipmunk. In the Tiger flying suit, goggles, and white leather gloves are a practicaility for comfort, warmth, and digt articulation. In the Chipmunk (mine at least) you need something overall like to collect the oil the engine throws out.
I know this post was about bars etc. but often it all gets lumped into the one by those with the benign environment of a C152 or PA28 cabin.
