Montbell U. L. Super Spiral Down Hugger #0 - Montbell has adapted a classic tailor's trick by integrating a woven fabric "cut on the bias".

Additionally, coiled or crimped fibers are used in the fabric weave to capitalize on their inherent stretch properties. To create an even more comfortable system we utilize an elastic stitch technique to create small "gathers" in the quilting.
