How much does that shirt weigh?
The shirts I sell usually vary between 6-16kg (1-2½ stone), though an authentic riveted mail shirt (every ring is riveted closed) can weigh in excess of 25kg (4 stone). Aluminium is approximately 32% lighter than steel, so a 6kg (1 stone) steel shirt would only weigh 2kg (4.5lb) if it was made from aluminium.
