Knitting for Olive merino wool comes from sheep bred in Patagonia, where mulesing is not practiced. The wool can be traced directly back to the farm it comes from. In this way, they know exactly which farm, farmers, and sheep made their wool. Merino wool has many excellent properties. It is temperature-regulating. That is, the wool keeps our bodies warm in cold weather, and releases heat in warm weather, keeping our skin cool. At the same time, wool, like silk, can carry moisture away from the skin, and can absorb 30% of its weight without feeling wet. Wool is also dirt-repellent and requires minimal care. The yarn is STANDARD 100 by OEKO-TEX® certified The yarn is produced in Italy. Their spinning mill follows ethical, technical and environmental standards, creating yarns free from harmful chemicals.
