A breathable diaper, feminine hygiene, or like disposable sanitary product construction includes a plurality of materials comprising, from the skin-facing side outwardly a topsheet of liquid- and vapor-permeable hydrophilic material. A core of highly absorbent material disposed outwardly of the topsheet for absorbing fluid received through said topsheet. The core has an inner surface in fluid communication with the topsheet, an outer surface and two lateral side surfaces. A barrier is formed of a multilayer non-woven material which is hydrophobic and vapor-permeable for limiting the outward escape of fluid therethrough while enabling the outward escape of heat and water vapor therethrough, such as a two-layer spunbond-meltblown or a three-layer spunbond-meltblown-spunbond. In use, the barrier is in a U-shaped configuration having a base disposed adjacent the core outer surface and a pair of flanges upstanding from the base and each extending inwardly adjacent to a respective one of the core lateral side surfaces. A backsheet is formed of a multilayer non-woven material which is hydrophobic and vapor-permeable for limiting the outward escape of fluid therethrough while enabling the outward escape of heat and water vapor therethrough, such as a two-layer spunbond-meltblown or a three-layer spunbond-meltblown-spunbond. The backsheet is disposed at least partially outwardly of the barrier base.
