1. A disposable absorbent hygiene product comprising:
a main part having a body facing surface intended to face a body of a user and a garment facing surface intended to face away from the body of the user,
the main part comprising a liquid permeable topsheet at the body facing surface, a liquid impermeable backsheet at the garment facing surface, and an absorbent assembly arranged between the topsheet and the backsheet, the main part having a front end and a back end, and defining a longitudinal direction from said front end towards said back end and defining a transversal direction perpendicular to the longitudinal direction,
wherein the absorbent assembly includes an imaginary longitudinal centerline and is divided by two, imaginary, transversally extending straight lines orthogonal to the imaginary longitudinal centerline into a front region towards said front end, having a longitudinal length of from 10% to 40% of a longitudinal length of the absorbent assembly; a back region towards said back end, having a longitudinal length of from 10% to 40% of the longitudinal length of the absorbent assembly; and a central region between said front region and said back region,
wherein in the front and back regions, the absorbent assembly comprises cellulosic fibers mixed with super absorbent polymers, with a super absorbent polymer concentration of from 0 to 30 weight %, based on a total weight of cellulosic fibers and super absorbent polymer, and a cellulosic fiber basis weight of from 50 to 200 g/m2;
wherein said central region provides from 70% to 100% of a total retention capacity of the absorbent assembly,
wherein the liquid permeable topsheet comprises at least one of a hydrophilically treated polypropylene spunbond nonwoven and spunbond/meltblown composite nonwoven, having a basis weight of from 8 to 20 g/m2; and
wherein an acquisition layer material is provided sandwiched between said topsheet and said absorbent assembly, being an through air bonded nonwoven having a basis weight of from 40 to 60 g/m2 and a caliper of at least 0.9 mm according at 0.5 kPa pressure.
