Sheep wool is a natural fiber obtained from the fleece of sheep. It is known for its warmth, softness, and durability, making it a popular material for clothing, blankets, and other textiles. Wool fibers are crimped, which helps trap air and provide insulation, keeping the wearer warm in cold conditions. Wool is also moisture-wicking, meaning it can absorb moisture without feeling wet, making it comfortable to wear. Additionally, it is biodegradable and renewable, as sheep produce new fleece each year. This makes wool an environmentally friendly choice compared to synthetic fibers.
