Merino wool socks. Uncranted, pleasantly thin, breathable and nice and warm. The knitted jaquard pattern is based on patterns of the Bauhaus period. Knitted in the Czech Republic. 65% merino wool, 29% polyamide (helps that the socks last longer), 6% Elasthan (keeps the socks in shape and ankle even after wearing a lot)) Hand washing Merino fibers are extremely fine. Human hair is about 70 micrometers (m) thick, while that of a merinoshaf is only 14.5 to 24.5m thick. One micrometer is a millionth meter: the finer the micrometer, the softer the fiber. The Merinogarn used in the Bauhaus series is one of the finest ever: 19.5m. This means that the yarn is exceptionally soft, incredibly light and not irritating. A thread thickness of 19.5m is often used for baby clothes or thermal underwear - clothing that is worn directly on the skin. A perfect choice for a Wolvis piece!
