A press felt comprising two stacked layers of a woven single layer base fabric (500, 700, 800), each of the layers of the base fabric being formed by a system of warp yarns (512, 712, 812) interwoven with first and second systems of weft yarns (540 - 552) according to a defined single layer repeating weave pattern, the two stacked layers (500, 700, 800) being needled with at least one batt layer, wherein in the woven single layer base fabric (500, 700, 800), the warp yarns (512, 712, 812) of the system of warp yarns are polymeric monofilaments arranged as a single layer and are interwoven with the weft yarns (540 - 552) in the first and second systems of weft yarns; the weft yarns of the first system of weft yarns comprise cabled polymeric monofilaments (540, 542, 544, 545, 547, 549, 550, 552) and the weft yarns of the second system of weft yarns comprise single polymeric monofilaments (541, 543, 546. 548, 551); the cabled polymeric monofilaments (540, 542, 544, 545, 547, 549, 550, 552) comprise from 50% to 85% of the weft yarns and the single polymeric monofilaments (541, 543, 546. 548, 551) make up from 50% to 15% of the weft yarns in one repeat of the base fabric weave construction; the cabled monofilaments are each comprised of at least two monofilaments which are cabled together; at least two of the cabled weft yarns in each repeat of the repeating weave pattern are adjacent to each other; characterized in that the warp yarns (512, 712, 812) pass over and under the weft yarns (540 - 552) of the first and second systems of weft yarns (540 - 552) such that under tension the cabled polymeric monofilaments (540, 542, 544, 545, 547, 549, 550, 552) of the first system of weft yarns crimp more than the single polymeric monofilaments (541, 543, 546. 548, 551) of the second system of weft yarns, thereby changing the yarn to yarn spacing, and in that a center line to center line first distance between any two adjacent ones of the weft yarns (540, 541; 545, 546) in one repeat of the repeating weave pattern differs from a corresponding center line to center line second distance between a second different set of adjacent ones of the weft yarns (544, 545) in the repeat, with both the first and the second distances (A, B) being different than a center line to center line third distance between a third different set of adjacent ones of the weft yarns (541, 542; 543, 544) in the repeat. the warp yarns (512, 712, 812) pass over and under the weft yarns (540 - 552) of the first and second systems of weft yarns (540 - 552) such that under tension the cabled polymeric monofilaments (540, 542, 544, 545, 547, 549, 550, 552) of the first system of weft yarns crimp more than the single polymeric monofilaments (541, 543, 546. 548, 551) of the second system of weft yarns, thereby changing the yarn to yarn spacing, and in that a center line to center line first distance between any two adjacent ones of the weft yarns (540, 541; 545, 546) in one repeat of the repeating weave pattern differs from a corresponding center line to center line second distance between a second different set of adjacent ones of the weft yarns (544, 545) in the repeat, with both the first and the second distances (A, B) being different than a center line to center line third distance between a third different set of adjacent ones of the weft yarns (541, 542; 543, 544) in the repeat.
