A papermaking fabric of the multilayer type having threads of a multiple layer thread system extending in one fabric direction and threads of a single layer thread system extending in the other fabric direction which are interwoven with the threads of each of the multiple layers. The threads of the single layer thread system are spaced apart from one another, and threads of the several layers are tiered above one another with spacing between tiers, so that the fabric has a significant projected open area that allows spray water to penetrate the fabric. The fabric may also have an increased void volume in its interior and binding points between thread systems that are well spaced from one another to enhance the papermaking qualities of the fabric.
