A microporous, multilayer material has a layer of microfibers having a weight of from about 0.5 to about 60 g/m2, the microfibers having diameters of from about 0.1 to about 10 microns. The microfiber layer is covered on opposite sides with nonwoven layers and all the layers are bonded together with a pattern of water repellent and, preferably, elastic paste members sufficiently penetrating through the layers. A process for making the microporous, multilayer material imprints the paste for the penetration-bonding paste members on one or both sides of the layers only squeezed dry after washing and water-repellentizing baths.
