Marino wool comes from merino sheep, usually from Australia or New Zealand. As with the alpaca yarns, wool is categorized by fibre weights. Wool that is characterized as "superfine" or "extra fine" has a maximum fibre weight of 19,5 micron. The super wash process makes it unshrinkable. Some of our Merinos are awarded the Öko-Tex Standard 1 Certificate, product category 1.
