Dale of Norway has a long and unique history of environmentally friendly products and production. Knitwear is made with 100% natural wool. The wool fiber is known as one of the most eco-friendly fibers available and is often called nature’s own high-tech fiber due to its superior properties. Besides using natural fibers, Dale of Norway’s production is powered by sustainable hydroelectric energy generated by local waterfalls in the Dale Valley — and only Oeko-Tex 100 certified products are used for production.
