Abstract
An article (20) has a front waistband section (38), a back waistband section (40), an intermediate section (42) interconnecting the front and back waistband sections, a longitudinal direction (86), a cross-direction (88) and a laterally extending line (100) which is longitudinally centered in the article (20). At least a first fit panel (36) is connected to an inside surface (66) of at least one of the waistband sections (38, 40), and the fit panel has a direction-dependent coefficient of friction value along a basis line (54) of the fit panel. A first coefficient of friction value is exhibited when sliding on the fit panel along the basis line in a first, inward basis direction (62) generally toward the lateral line and a different second coefficient of friction value is exhibited when sliding on the fit panel along the basis line in a second, outward basis direction (64) which is opposite the first basis direction (62).
