Valued for flexibility in combat, chain mail was the primary defensive armor in Europe for more than one thousand years, through the entirety of the Medieval Period. To create a 'chain mail' or 'maille' garment, thousands of rings would be punched out whole or riveted from strands of wire. A blacksmith would weave the rings into sheets using a pattern of interlocking rings. Patterns varied by region, dictated by armaments and fighting styles. Given the labor-intensive process of weaving, chain mail garments were costly to purchase but relatively simple to repair.

After being built, chain mail would go through a process called proofing to assure it could stand up to blows during battle. “Armour of proof” or specifically “mail of proof” was chain mail that had been found to survive shots from arrows or jabs from swords. Of course, the very existence of this designation suggests that plenty of chain mail was not strong enough to handle tough blows, especially as weapons became more advanced, like the rise of the longbow in the 14th century. For all its benefits, chain mail was no guaranteed protection against attack.
