From the site: Pure Wool turtleneck crafted in Spain. Extra roomy and cozy. Knitted in our local wool. This wool is very special as it all comes from our sheep, shepherds and artisans in Northern Spain. This shade is non-dyed, made directly with the fleece from our sheep. Our local wool feels like a hug. It is a strong and very pure yarn that softens and adapts to you over time. A very resistant and classic wool, perfect for timeless knitwear. We care about animals and we can assure you that all local sheep providing this wool have been treated with care.
