Our Chunky Wool comes from the carding of short wool fibers that are arranged to obtain a more voluminous, fuzzier, and warmer yarn. The typical softness and thermal capacity of this woolen yarn are a result of the traditional spinning method. The carding process brings the finer fibers to the surface and traps microscopic air bubbles inside the yarn, making it soft and warm while keeping it lightweight. The extra-fine fibers are 18.5 microns thick, they are certified to guarantee the highest quality and are completely traceable, from the fibers up to the final knit. The Woolen Ribbed Overshirt
