An absorbent article includes a fit system having fasteners and friction elements. The fasteners are located in the front waist area and the back waist area and are adapted to fasten the article about the waist of a wearer to define a waist opening, a pair of leg openings, and a pair of overlap regions. The friction elements are located in the overlap regions and are adapted to provide friction between the front waist area and the back waist area in the overlap regions. The friction elements have an upper portion oriented towards the waist opening and a lower portion oriented towards the leg opening. The upper portion and the lower portion have different concentrations of surface treatment, thicknesses, and/or surface areas.
