Linothorax vs Quilted linen vs spolas

[Dan Howard]

If those torso plates don't overlap then you are going to have problems when you test this configuration against spear thrusts and arrows when they lodge in the gaps. This is why historical plate armour almost always overlaps. I've also never seen an example of historical armour with long plates aligned vertically like this unless they were articulated with mail (i.e. "mail and plates" construction).
