a first woven-fabric layer forming a web material contact side, said first woven-fabric layer being formed by interwoven first longitudinal threads that run in a clothing longitudinal direction and first transverse threads that run in a clothing cross direction; and
a second woven-fabric layer forming a machine contact side, said second woven-fabric layer being formed by interwoven second longitudinal threads that run in the clothing longitudinal direction and second transverse threads that run in the clothing cross direction;
said first woven-fabric layer and said second woven-fabric layer being connected to one another via binder threads;
a number of first longitudinal threads in the clothing being greater than a number of second longitudinal threads, but being at most double the number of second longitudinal threads; and
a weaving pattern of the clothing recurring in repeats, and the second transverse threads in each repeat forming at least two contact floats on the machine contact side, with all contact floats of the second transverse threads having a length of at most two;
said first longitudinal threads and said second longitudinal threads in each repeat being disposed in a plurality of groups, with at least one first group and one second group, wherein the first group is formed of one first longitudinal thread and one second longitudinal thread that are disposed exactly on top of one another in a thickness direction of the clothing, while the second group is formed of two first longitudinal threads and one second longitudinal thread, and wherein none of the two first longitudinal threads of the second group is disposed exactly above the one second longitudinal thread of the second group in the thickness direction of the clothing.
