摘要： An absorbent article having a topsheet, a backsheet arranged on the garment-facing side, an absorbent core enclosed between the topsheet and the backsheet and a pair of standing gathers. The topsheet and the standing gathers comprise sheet materials with specified stiffness, softness and smoothness properties. The absorbent article may be a diaper or incontinence guard.
