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: • a core wrap (16, 16') comprising a top layer and a bottom layer; • an absorbent layer between the top layer and the bottom layer, the absorbent layer comprising an absorbent material and 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; • 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) which is less than 10 mm away from the centerline of the closest folding guide and extending outward from this proximal side, wherein each winglet is completely separated from the neighboring winglets, and wherein neighboring winglets are separated by a gap between their neighboring sides (6202-6211, 6213-6221); wherein the top layer of the core wrap is bonded to the bottom layer of the core wrap through the folding guides and at least some of the gaps between the winglets; and 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. - 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: • a core wrap (16, 16') comprising a top layer and a bottom layer; • an absorbent layer between the top layer and the bottom layer, the absorbent layer comprising an absorbent material and 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; • 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) which is less than 10 mm away from the centerline of the closest folding guide and extending outward from this proximal side, wherein each winglet is completely separated from the neighboring winglets, and wherein neighboring winglets are separated by a gap between their neighboring sides (6202-6211, 6213-6221); wherein the top layer of the core wrap is bonded to the bottom layer of the core wrap through the folding guides and at least some of the gaps between the winglets; and 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. • a core wrap (16, 16') comprising a top layer and a bottom layer; • an absorbent layer between the top layer and the bottom layer, the absorbent layer comprising an absorbent material and 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; • 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;
