A triple layer forming fabric includes: a set of top machine direction yarns; a set of top cross machine direction yarns interwoven with the top machine direction yarns to form a top fabric layer; a set of bottom machine direction yarns; a set of bottom cross machine direction yarns interwoven with the bottom machine direction yarns to form a bottom fabric layer; and a plurality of stitching yarns interwoven with the top and bottom fabric layers. A pair of first and second stitching yarns is positioned between adjacent pairs of top cross machine direction yarns; the first and second stitching yarns of each pair are interwoven with the top and bottom machine direction yarns such that, as a fiber support portion of the first stitching yam is interweaving with the top machine direction yarns, a binding portion of the second stitching yarn is positioned below the top machine direction yarns, and such that as a fiber support portion of the second stitching yarn is interweaving with the top machine direction yarns, a binding portion of the first stitching yam is positioned below the top machine direction yarns. The first and second stitching yarns cross each other as they pass below a transitional top machine direction yarn, and each of the binding portions of the first and second stitching yarns passes below at least one of the bottom machine direction yarns. The top machine direction yarns, top cross machine direction yarns, and fiber support portions of the stitching yarns interweave to form a plain weave surface. The top machine direction yarns have a first diameter, the bottom machine direction yarns have a second diameter, and the top cross machine direction yarns have a third diameter, and a ratio of the first diameter and the second diameter is between about 0.75 and 0.95, and a ratio between the first diameter and the third diameter is between about 0.8 and 1.1.
