An absorbent article, such as a diaper, sanitary napkin, incontinence guard or panty liner, including a fluid-permeable nonwoven topsheet located on the wearer-facing side thereof. The nonwoven topsheet includes a plurality of channels arranged side-by-side. The channels are located within the nonwoven topsheet, whereby gas is allowed to pass into, out of and along the channels, thus providing ventilation of the absorbent article.
