Abstract
An absorbent article such as a diaper can include three or more absorbent core structures for improved acquisition speed, reduced bulkiness, increased retention capacity, and improved dryness, including over multiple insults. The three or more absorbent core structures can at least partially overlap in a stacked or layered configuration in an insult zone of the article. At least one of the core structures can include an absorbent polymer or airlaid material. The absorbent polymer can be located primarily in the insult zone, and one or more of the absorbent core structures can extend beyond the insult zone. In an example, each of the at least three absorbent core structures has a different body-side surface area.
