Merino wool comes from Merino sheep, primarily raised in Australia, New Zealand, and parts of South America. It is valued for its fine fibers, natural temperature regulation, and softness against the skin. Ethical considerations include animal welfare practices such as mulesing and land management. Responsible sourcing programs and certifications help promote better animal treatment and traceability. Merino wool is commonly used in knitwear, base layers, and performance garments for its breathability and comfort.

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.
