Mechanical fastening system with grip tab

A distinctive article can include an elastomerically stretchable side panel having a longitudinal dimension and a lateral dimension. A member of hook material is operable connected to a first, laterally outboard edge portion of the side panel, and each member of hook material includes a hook base layer which has an appointed fastening region and an appointed grip region. The fastening region has a plurality of hook elements which are integrally formed with the base layer and extend away from a base plane of the hook base layer. The hook elements are configured to operably engage a selected, co-operating loop material. The grip region has a relatively lower density of the hook elements per unit area, as compared to the fastening region. The fastening region is interposed between the side panel and the grip region. The grip region provides a laterally terminal edge of the article.
