Abstract
Described herein is a substrate including a central longitudinal axis, a first support web, and a second support web. A sinuous web may be positioned between the first support web and the second support web. The sinuous web may include transverse web portions and bridging web portions, where the bridging web portions alternatively connect ends of adjacent transverse web portions. The sinuous web may be connected to the first support web by support legs extending between bridging web portions and a surface of the first support web. The sinuous web may be connected to the second support web by support legs extending between bridging web portions and a surface of the second support web. A support leg length to distance between transverse web portions ratio may be from about 1.0 to about 4.0.
