A disposable absorbent article comprising:
- a) a vapor permeable, liquid impervious, backsheet laminate;
- b) a liquid pervious topsheet which is positioned in facing relation with said backsheet;
- c) an absorbent core located between the backsheet laminate and the topsheet;
- d) a first side panel and a second side panel, each disposed in a back waist region;
- e) an elastic waist feature;
- f) laterally opposed leg cuff elastics;
- g) a landing zone;
- wherein a backsheet film is joined to a nonwoven on a garment-facing side to form the vapor permeable, liquid impermeable, microporous backsheet laminate;
- wherein the vapor permeable, liquid impermeable, microporous backsheet laminate has a dynamic fluid impact value of less than about 10 g/m2;
- wherein the backsheet film comprises a plurality pores and a plurality of capillaries running therebetween and connecting the plurality of pores, and wherein the backsheet is joined to the topsheet on a wearer-facing side of the backsheet;
- wherein the laterally opposed leg cuff elastics are disposed parallel to each other and parallel with a longitudinal axis of the absorbent article, and wherein the leg cuff elastics are joined to the backsheet;
- wherein side edges of the landing zone extend laterally outboard of side edges of the absorbent core;
- wherein side edges of the waist elastic feature extend laterally outboard of the side edges of the absorbent core in the back waist region;
- wherein the plurality of capillaries extend between the wearer-facing side of the backsheet film and the garment-facing side of the backsheet film;
- wherein the backsheet film is from about 0.25 mils to about 2.5 mils;
