The early coat of plates is often seen with trailing cloth in front and back, such as seen on the 1250 St. Maurice coat. These has been described as metal plates riveted to the inside of a surcoat. There is debate regarding whether the plates inside the armoured surcoat overlapped, but the armour is otherwise similar. Quantitatively speaking, however, most of the known evidence for coat of plates and brigandines dated from 14th and 15th centuries actually displays arrangements of overlapping plates; and although there are exceptions to this rule, they are not many.
