Schachenmayr Regia Premium Merino Yak is a premium quality product of 58% merino wool from South Africa and 14% yak. The uncolored yak fibers in natural brown colors provide the melange effect of the colors. The Yak with a special fiber content ensures a pleasantly soft wearing comfort, very warm, robust and yet light. Regia Premium Merino Yak knits like the normal Regia 4-wire. Beautiful yarn for Fair Isle and cable patterns.
