Pair of plates
A pair of plates (modern: coat-of-plates) is a term used to describe the type of armour that consisted of metal (typically iron) plates rivetted to the inside of a fabric or leather covering. Sometimes the plates might be found onthe outside of the armour. The covering typically formed a t-shaped garment when laid flat with the sides wrapping around to buckle at the back. Sometimes the front and back pieces were separate and might be laced or buckled at the sides.
Some of the best known known examples of this type of armour come from the Battle of Wisby fought in Wisby in 1361.
