mediumaevum:

Tobias Capwell in his custom made armour, based on an effigy from about the 1450s. It is a beautifully tailored second skin designed to protect him while jousting or (with a different helmet) in foot combat.

Properly made armour does not restrict movement, armour like this actually has a greater range of movement than the human inside it.

For those of you unfamiliar with Tobias, he is a big name on the jousting international scene.
