Chainmail
Flexible armor of interlocked metal rings
Chainmail is a flexible armor made by linking tens of thousands of small metal rings together, each secured with a rivet in the common 4-in-1 pattern. First developed by the Celts around the 5th century BC, it remained in widespread use across Europe for over a millennium until the 15th century. Weighing 10-15kg and offering excellent protection against slashing attacks, it was typically worn over a gambeson to absorb blunt impact.
