Abstract
A distinctive absorbent garment article generally delimits a front waistband section, a rear waistband section and an intermediate section which interconnects the front and rear waistband sections. The article has a substantially fluid-impermeable backsheet layer, a liquid permeable topsheet layer, positioned in facing relation with the backsheet layer, and an absorbent body located between the backsheet layer and topsheet layer. The absorbent body includes a distinctive humidity transfer region which is advantageously configured to exhibit relatively low moisture retention. A vapor permeable panel is connected to the backsheet layer at one or more waistband sections of the article, and is arranged in an overlying registry with the humidity transfer region of the absorbent body.
