Wool comes from the fleece of sheep raised in regions such as Australia, New Zealand, Europe, and South America. Sheep are typically shorn annually, allowing the fiber to regenerate naturally. Wool is biodegradable, moisture-regulating, and resistant to odor, but sustainability depends on animal welfare, land management, and grazing practices. Responsible sourcing focuses on ethical treatment of animals and ecosystem preservation. Wool is used in sweaters, outerwear, blankets, rugs, and home textiles, valued for its performance and longevity.

Common wool types include Merino, Shetland, and Lambswool, each with different textures and qualities.
