...and what about gloves? When I was learning, I vowed that, until I got the licence, I would not (a) fly in a leather jacket or (b) wear gloves. Since then I have been bought the former by my wife and my army flingwinger mate has nicked me some of the latter (green ones: much nicer than the white ones the instructor wore to point at the ASI when speechless with mind-shattering terror).
As for a flying suit, I'll buy one when I get a share in an upside-downy aeroplane, and until then keep borrowing my air force buddy's festering green one: doesn't have kneepads, but it does have a nice picture of Marvin the Moose on the shoulder, and comes in handy for swabbing out Gipsy Major engine compartments at the end of the day.
