Abstract

A disposable absorbent article includes a multi-functional fastening system which includes a pair of primary fasteners which are located on the opposed side edges in one of the waist regions of the absorbent article. The primary fasteners are configured to releasably engage the opposite waist region of the absorbent article. The fastening system also includes at least one secondary fastener which is located in one of the waist regions of the absorbent article. The secondary fastener is configured to releasably engage the opposite waist region of the absorbent article to conform the waist regions of the article to a wearer'"'"'s body after the primary fasteners have been releasably engaged. The primary fasteners may be prefastened to allow the disposable absorbent article to be pulled on or off over the wearer'"'"'s hips. The fastening system may further include a belt segment to which the secondary fasteners are attached.
