What is "mail"?

Mail, also known as chainmail, is a type of armor made from interlocking metal rings, typically worn by medieval soldiers and knights. It consists of thousands of metal rings linked together in a pattern, forming a flexible and durable fabric-like material. The rings can be made of various materials such as iron, steel, or bronze, and come in different sizes and thicknesses depending on the desired level of protection. Mail was designed to protect the wearer from cuts and punctures during battles, but it was relatively heavy and could be cumbersome to wear. Despite its limitations, it was a popular and effective form of armor for centuries.
