A late mediaeval knight is travellíng through an area he knows to be dangerous but in which an attack is not guaranteed. Does he wear his armour all day?

He'd probably be wearing an "Arming doublet", under a rather more dressy garment. It was a sort of padded jacket worn under armour, with mail gussets to protect armpits etc. See the illustrations here: http://www.myarmoury.com/talk/viewtopic.php?t=21451
