Fine mail

I think you meant "fine mail"!

Fine mail refers to a type of medieval armor that was made from interlocking iron rings, similar to chain mail. It was a popular type of armor during the 12th to 15th centuries, particularly among knights and men-at-arms.

Fine mail was characterized by its small, tightly woven rings, which were often made from iron wire or steel. The rings were typically around 1-2 mm in diameter, and were linked together to form a flexible, yet protective, garment.

Fine mail was considered a superior type of armor because it was more flexible and allowed for greater mobility than other types of armor, such as plate armor. It was also more effective at stopping arrows and other projectiles, as the interlocking rings could absorb and distribute the impact of the projectile.

However, fine mail was also more expensive and time-consuming to produce than other types of armor, which limited its use to wealthier warriors and nobles.
