Cashmere is characterized as luxuriously soft, with high napability and loft. It is noted as providing a natural light-weight insulation without bulk. Cashmere is extremely warm (in order to serve its original purpose of protecting goats from cold mountain temperatures.) Fibers are highly adaptable and are easily constructed into fine or thick yarns, and light to heavy-weight fabrics Appropriate for all climates, a high moisture content allows insulation properties to change with the relative humidity in the air.
