Highland wool, made from the wool of sheep raised in the high altitudes of Peru. Compared to the wool of lowland sheep, the wool of mountain sheep, which live in harsh, high-altitude environments, is stronger, more supple, and has excellent moisturizing properties. The yarn is produced using old machinery, resulting in unevenness in each individual thread, giving it a rustic and tasteful texture. The moderately thick knit fabric is not heavy and is soft and easy to wear. It has excellent heat retention and can be worn warmly by layering it over cut-and-sewn shirts or blouses. This is a near-mint item, only tried on, but the upper left corner of the tag is detached. If you wish, I can repair it for you.
