Quilted armor? Helmets?

[Dan Howard]

It is fine against slashing blows but pretty much anything will stop a sword cut. It won't stop an arrow or spear thrust which was the primary threat during the time in question. Leather armour designed to stop these weapons is multi-layered. Two-three layers was common but up to seven layers were used for weaker leather. Crocodile hide makes weak leather and pretty crappy armour, though I've had no experience with croc rawhide.
