Sheep wool is a natural fiber produced by sheep, serving as their protective covering. It is crimped, elastic, and grows in clusters called staples. Wool is highly valued for its insulating properties, which keep the sheep warm in cold weather and cool in heat due to its breathability. It is also water-resistant, flame-resistant, and durable. Wool is sheared from sheep typically once a year without harming the animal. It is then cleaned, spun into yarn, and used in textiles for clothing, blankets, and insulation. Wool's versatility and biodegradability make it a favored material in both traditional and high-end fashion.
