First things first, let’s sort out the difference between cashmere and wool. Cashmere is the fine, soft fiber combed from the undercoats of certain goats. This undercoat is extremely soft and downy, and it’s protected by the goat’s outer layer, AKA the wool. Cashmere gets its name from an old spelling of Kashmir, the region where its production and trade originated. While wool and cashmere are both natural materials and renewable fibers, cashmere is the finest, softest, and most durable yarn, making it much more sought after than wool for its special properties.
