The fabric is made using the finest 24.5μ baby mohair, which is considered the top-grade weaving yarn among domestic worsted spun yarns. Baby mohair, with its incredibly fine fibers, poses a great challenge in spinning, and only a limited number of skilled artisans are capable of working with such delicate yarn. As a result, there are very few factories equipped to handle this material. While typically such delicate fibers would easily break when knitted, this particular yarn is predominantly used for weaving, making it an exceptionally rare material.
