Abstract

The present invention relates to a disposable absorbent article, such as a diaper, training pants, adult incontinence article, having a specific topsheet with an opening to receive bowel movement waste (BM) and which is such that it masks the waste present underneath said topsheet. The topsheet is air permeable and it has a uniform pore size distribution with small pores only and it has a low surface energy and therefore an alcohol repellency of at least 7, typically at least 9 or even preferably 10.
