The cuir bouilli cuirass is an inexpensive form of plate armour made from hardened leather. Tanned hides are soaked in hot salt water, tooled into interlocking plates, then dried and waxed. This produces a rigid shell offering greater protection than a leather jack without the weight of metal plate.
The cuirass can be cut off with a knife or light slashing weapon as an action. It must then be repaired before reuse, at nominal expense with smith’s or leatherworker’s tools.
