1. A knit, water-vapor permeable, water-responsive, shape-memory wool fabric comprising:
a plurality of descaled wool fibers twisted into single yarns at a twisting density of 100 to 600 twists per meter of fibers; and
multi-ply yarns formed from the single yarns and having a twisting frequency of 200 to 700 twists per meter of the single yarns, the multi-ply yarns being steam set to form shape-memory multi-ply yarns;
wherein the shape-memory multi-ply yarns being formed into a first knitting pattern including dynamic pore openings reversibly responsive to an absorbed fabric water content, such that the knit, water-vapor permeable, water-responsive, shape-memory wool fabric has a pore area percentage that reversibly increases from zero percent pore area at zero percent fabric water absorption to approximately 70% pore area at approximately 75 percent fabric water absorption.
