A vapor-permeable laminate () with at least one first outer layer () and at least one second outer layer (), the outer layers () having perforations () and being joined to one another in such a way that the perforations of the first outer layer () do not coincide with the perforations () of the second outer layer (), and a structure () having pores () being provided between the outer layers (). In order to achieve sufficient vapor permeability with at the same time sufficient hydrostatic seal-tightness, it is provided that each of the pores () has a clear cross-sectional area (A) of less than 200 &#x3bc;m.
