A very soft, silky wool obtained from a small wild llama (Vicugna vicugna) that is found mainly at high altitudes (12,000 to 17,000 feet) in Ecuador, Bolivia, and Peru. The vicuna produces a fine, downy fleece that is valuable. The straight, silk-like wool is rare. It is generally left undyed in its natural white or cream color. Vicua is used for coats, suits, and soft shawls.
