Cashmere sweaters are made from the soft undercoat of the cashmere goat, primarily found in regions like Mongolia and China. Known for their luxurious feel, these sweaters are lightweight yet provide excellent warmth, making them a popular choice for colder weather. The fibers used in cashmere sweaters are finer and softer than regular wool, resulting in a comfortable fit. Due to the labor-intensive process of collecting cashmere, these sweaters can be more expensive than those made from other materials. Proper care, such as hand washing and storing them flat, can help maintain their quality and longevity.
