Wool is a natural protein fiber obtained from the fleece of sheep. It is sheared, cleaned (scoured), and spun into yarn. Wool’s structure features natural crimps and scales, which give it elasticity, insulation, and moisture-wicking properties. It keeps the body warm even when damp and resists odor, making it a preferred material for cold-weather clothing and activewear. Common wool types include Merino, Shetland, and Lambswool, each with different textures and qualities.

Wool is renewable and biodegradable, though its environmental impact depends on farming practices. Ethical sourcing standards such as ZQ-certified wool, Responsible Wool Standard (RWS), and mulesing-free certifications help address animal welfare, land use, and traceability. Wool is used in clothing, outerwear, home textiles, and accessories — valued for its performance and durability.
