Made of 100% wool, these wrist warmers are equipped with thumb holes. The boiled felt wool offers a bit of protection from the wind as well as binding warm air. A touch of luxurious warmth to Nordic frosts! *How does boiled wool differ from felted wool?* A boiled wool product is first knitted into shape, and then treated with hot water. The result is more flexible and elastic than felt, but more dense than the original knit. In felting, loose wool fibers are used instead of yarn, and the final product is relatively stiff. - The felt's material weight is a whopping 800g/m² - Hand or machine wash 30ºC with wool detergent and wool cycle, don't use bleach or fabric softeners - Hang dry in room temperature - Bluesign certified product - Made in Europe The main image displays the colour you're ordering.
