Cashmere wool is a luxurious fiber obtained from the undercoat of cashmere goats, primarily found in regions like Mongolia and China. Known for its softness, warmth, and lightweight properties, cashmere is often used in high-quality clothing such as sweaters, scarves, and shawls. The production of cashmere wool is labor-intensive, as each goat produces only a small amount of fiber annually. This rarity contributes to its higher price compared to other types of wool. Cashmere is also valued for its insulating qualities, making it a popular choice for winter garments.
