Abstract: The present invention relates to a fluid-absorbent article, comprising a fluid-absorbent core, comprising from 0 to 90% by weight fibrous material and from 10 to 100% by weight water-absorbent polymer particles having a mean sphericity (SPHT) from 0.8 to 0.95, based on the sum of water-absorbent polymer particles and fibrous material;and an acquisition-distribution layer between having a three dimensional apertured structure having a femal side (5) and a male side (6), wherein the femal side presents a multiplicity of openings extending in the form of through holes in the direction of a lower surface of the same structure being the male side, wherein the quantity of the water absorbent polymer particles within the fluid absorbent core is at least 3 g.
