Cashmere wool, usually simply known as cashmere, is a fiber obtained from cashmere goats and other types of goat.

Common usage defines the fiber as wool but is finer and softer, giving its characteristics as compared to sheep's wool. Some say it is hair, but as seen below, cashmere requires the removal of hair from the wool. The word cashmere is an old spelling of the Kashmir region in northern India and Pakistan. Cashmere is fine in texture, strong, light, and soft. Garments made from it provide excellent insulation, approximately three times that of sheep wool. Cashmere is also softer than regular wool.
