Splint Mail is at the beginning of the game, a good set of body armor; it gives better protection than Chain Mail. It has an armor class of 4, and offer an armor class of 3 against piercing and missile attacks and A.C. 2 against blunt weapons. It is reasonably priced and not too heavy.
Splint Mail is a variant of banded mail in which the metal strips are applied vertically to the backing of chain, leather, or cloth rather than horizontally as in banded mail. Since the human body does not swivel in mid-torso as much as it flexes back to front, splint mail is more restrictive in battle.
