A hauberk or byrnie is a mail shirt. The term is usually used to describe a shirt reaching at least to mid-thigh and including sleeves. A haubergeon ("little hauberk") refers to a smaller mail shirt, that was sometimes sleeveless, but the terms are occasionally used interchangeably. Mail armor, likely invented by the Celts, became widely adopted for its flexibility and spread throughout Europe and Asia, becoming a staple in Roman legions and medieval warfare. By the 11th century, the hauberk evolved into a knee-length, sleeved mail shirt, as depicted in the Bayeux Tapestry and it remained in use in Europe until the Renaissance despite the rise of plate armor.

👉 Hauberk in the context of Chain mail
Mail (sometimes spelled maille and, since the 18th century, colloquially referred to as chain mail, chainmail or chain-mail) is a type of armour consisting of small metal rings linked together in a pattern to form a mesh. It was in common military use between the 3rd century BC and the 16th century AD in Europe, while it continued to be used militarily in Asia, Africa, and the Middle East as late as the 18th century. Even today it is still in use in industries such as butchery and as protection against the powerful bites of creatures such as sharks. A coat of this armour is often called a hauberk or sometimes a byrnie.

Hauberk in the context of Coat of plates
A coat of plates is a form of segmented torso armour consisting of overlapping metal plates riveted inside a cloth or leather garment. The coat of plates is considered part of the era of transitional armour and was normally worn as part of a full knightly harness. The coat saw its introduction in Europe among the warring elite in the 1180s or 1220s and was well established by the 1250s. It was in very common usage by the 1290s. By the 1350s it was universal among infantry militias as well. After about 1340, the plates covering the chest were combined to form an early breastplate, replacing the coat of plates. After 1370, the breastplate covered the entire torso. Different forms of the coat of plates, known as the brigandine and jack of plates, remained in use until the late 16th century.

Transitional armour describes the armour used in Europe around the 13th and 14th centuries, as body armour moved from simple mail hauberks to full plate armour.
The couter was added to the hauberk to better protect the elbows, and splinted armour and the coat of plates provided increased protection for other areas.
