Apparatus and associated methods relate to a body-worn unitary harness having a shoulder portion and a waist portion in tensile communication with one another, such that both the shoulder and the waist portions can be simultaneously adjusted using a single adjustment mechanism to conform to a wearer’s body. In an illustrative embodiment, a length of webbing may thread through an angle-turning buckle and change direction therein. Tensile forces in the length of webbing may be directed in different directions on either side of the angle-turning buckle.
