In the early dynasty, chain mail and plated mail that were used during the late Goryeo dynasty remained in usage, while lamellar armour, the traditional form of Korean armor, also persisted with some influences from the Mongols received during the 13~14th centuries. A full metallic armour set was composed of a helmet bearing much resemblance with regards to European kettle hats with attached neck defences of mail or lamellae, a body armour reaching down to the thighs or knees, and a set of shoulder guards which protected the upper arm as well.
