This special yarn comes from rare fibers found in the undercoat of cashmere goats. These particular goats live mainly in Mongolia and China, a region characterized by wide temperature fluctuations between seasons.
Cashmere goats adapted to this harsh climate by developing a double fleece: an outer guard layer that protects the undercoat from water, and an undercoat made of ultra-fine hairs with strong insulating properties. This keeps the goats warm in the winter but not too hot in the summer.
