This sturdy leather coat is reinforced with metal plates sewn into the lining.

Benefit: More cumbersome than light armor but less effective than most medium armors, the advantage of an armored coat is that a person can don it or remove it as a move action (there is no “don hastily” option for an armored coat). If worn over other armor, use the better AC bonus and worse value in all other categories; an armored coat has no effect if worn with heavy armor. The only magic effects that apply are those worn on top.
