(c) an absorbent core disposed between the topsheet and the backsheet, wherein the absorbent core comprises an upper layer comprising an upper surface and a lower surface opposite the upper surface and a lower layer comprising an upper surface and a lower surface opposite the upper surface, the upper layer comprising an open celled foam and the lower layer comprising a fibrous network;

(f) wherein the absorbent article has a transverse center line;

(g) wherein the upper layer comprises a perimeter comprising two or more discontinuous portions within the perimeter, wherein a first discontinuous portion has a first perimeter, wherein a second discontinuous portion has a second perimeter, wherein the first discontinuous portion and the second discontinuous portion are not in direct contact, wherein each of the two or more discontinuous portions is visibly distinct, and wherein each of the two or more discontinuous portions comprise of an area of at least 150 mm 2 ;
