The absorbent article comprises at least a topsheet layer and a backsheet layer, each layer having a body facing surface and a garment facing surface, and longitudinal and transversal edges, the article having a longitudinal front portion, a longitudinal back portion and a crotch portion located between the front and the back portion. The article comprises a first and a second zone of microencapsulated phase change material on a surface of a layer of the article. The first and second zones are selected form zones having different microencapsulated phase change materials, different concentrations of a microencapsulated phase change material or comprise microencapsulated phase change material having different phase change temperature intervals.
