A fastening member formed from a material web having a machine direction and a cross direction, comprising: a first layer formed of a first nonwoven web comprising fibers, the first layer having first and second opposing sides, the first side having a surface area; a proximal region including a first portion of the first layer and having a proximal region surface area that comprises a first portion of the surface area; and a distal region including a second portion of the first layer and having a distal region surface area that comprises a second portion of the surface area, the distal region comprising a second layer formed of a polymeric film bonded to the first layer at a plurality of bond sites arranged in a pattern, the bond sites comprising areas in which structures of the first and second layers are compressed together; the proximal region also comprising a third layer comprising an elastomeric film, wherein the proximal region has a first tensile strength in the cross direction and the distal region has a second tensile strength in the cross direction, and the second tensile strength is greater than the first tensile strength; wherein the proximal region has a first stiffness and the distal region has a second stiffness, and the second stiffness is greater than the first stiffness; and wherein fibers of the first layer and polymeric film of the second layer are formed at least in part of polymers of like chemistry.
