The present invention relates to a fluid-absorbent article, comprising a water-absorbent core with a basis weight of the fluid-absorbent core at the insult zone of at least 500 gsm, comprising 10 to 100% by weight water-absorbent polymer particles, wherein the water-absorbent polymer particles having a mean sphericity (SPHT) from 0.8 to 0.95 and satisfying the following conditions: (a) the sum of centrifuge retention capacity (CRC) and absorbency under high load (AUHL) being at least 60 g/g, and/or (b) the log10(SFC) > 5.7 - 0.138 x CRC, with SFC being not less than 5, wherein the CRC is given in g/g and the SFC in 10-7cm3-s/g. La présente invention concerne un article absorbant les fluides, comprenant un cœur absorbant l'eau ayant une masse surfacique du cœur absorbant les fluides à la zone d'attaque d'au moins 500 grammes par mètre carré (gsm), comprenant 10 à 100% en poids de particules de polymère absorbant l'eau, les particules de polymère absorbant l'eau ayant une sphéricité moyenne (SPHT) de 0,8 à 0,95 et satisfaisant les conditions suivantes : (a) la somme de la capacité de rétention centrifuge (CRC) et de l'absorbance sous charge élevée (AUHL) étant d'au moins 60 g/g, et/ou (b) le log10(SFC) > 5.7 - 0.138 x CRC, SFC étant non inférieur à 5, le CRC étant donné en g/g et le SFC en 10-7cm3-s/g.
