An absorbent article having a wearer-facing side and a garment-facing side, and extending in a longitudinal direction and a transversal direction, the article comprising: - a topsheet on the wearer-facing side; - a backsheet on the garment-facing side; - an absorbent core between the topsheet and the backsheet, wherein the absorbent core comprises an absorbent layer enclosed in a core wrap (16, 16') formed by a top layer and a bottom layer, the absorbent layer comprising an absorbent material comprising up to 50% by weight of cellulose fibers by weight of the absorbent material in the absorbent core, and the absorbent layer having a longitudinally-extending central portion, a first side portion disposed transversally outward of the central portion and a second side portion disposed transversally outward of the central portion on another side of the central portion; wherein the absorbent core further comprises a first folding guide between the central portion and the first side portion, and a second folding guide between the central portion and the second side portion; wherein each side portion comprises a plurality of winglets (610-613, 620-623), each winglet having a proximal side (6200, 6210, 6220) relative to a folding guide and extending outward from this proximal side, and wherein neighboring winglets are separated by a gap between their neighboring sides (6202-6211, 6213-6221); wherein when the absorbent core is folded along the folding guides, the central portion and the side portions form a three-dimensional basin and the gaps between the winglets decrease, the neighboring sides optionally coming into contact; the article further comprising: - at least one liquid management layer (52, 54) between the topsheet and the absorbent core, wherein the liquid management layer is a liquid distribution layer comprising unbound or loosely bound hydrophilic fibers; or the liquid management layer is an acquisition layer comprising a nonwoven material; or the absorbent article comprises a first liquid management layer which is a liquid distribution layer as indicated above and a second liquid management layer which is an acquisition layer as indicated above, and wherein the at least one liquid management layer comprises a pair of folding guides at least partially superposed with the folding guides of the absorbent core. - a topsheet on the wearer-facing side; - a backsheet on the garment-facing side; - an absorbent core between the topsheet and the backsheet, wherein the absorbent core comprises an absorbent layer enclosed in a core wrap (16, 16') formed by a top layer and a bottom layer, the absorbent layer comprising an absorbent material comprising up to 50% by weight of cellulose fibers by weight of the absorbent material in the absorbent core, and the absorbent layer having a longitudinally-extending central portion, a first side portion disposed transversally outward of the central portion and a second side portion disposed transversally outward of the central portion on another side of the central portion; wherein the absorbent core further comprises a first folding guide between the central portion and the first side portion, and a second folding guide between the central portion and the second side portion; wherein each side portion comprises a plurality of winglets (610-613, 620-623), each winglet having a proximal side (6200, 6210, 6220) relative to a folding guide and extending outward from this proximal side, and wherein neighboring winglets are separated by a gap between their neighboring sides (6202-6211, 6213-6221); wherein when the absorbent core is folded along the folding guides, the central portion and the side portions form a three-dimensional basin and the gaps between the winglets decrease, the neighboring sides optionally coming into contact; the article further comprising: - at least one liquid management layer (52, 54) between the topsheet and the absorbent core, wherein the liquid management layer is a liquid distribution layer comprising unbound or loosely bound hydrophilic fibers; or the liquid management layer is an acquisition layer comprising a nonwoven material; or the absorbent article comprises a first liquid management layer which is a liquid distribution layer as indicated above and a second liquid management layer which is an acquisition layer as indicated above, and wherein the at least one liquid management layer comprises a pair of folding guides at least partially superposed with the folding guides of the absorbent core.
