The Natural Grey Double Royal Stitch Zip Up is developed with exceptional attention to detail. It features Merino extra fine Slow Wool, offering quality and comfort that meets strict ÖKO-Tex and RWS standards, as well as a multi-thread knit double bead catcher which gives more than 10,000 meters of merino wool, knitted tightly for maximum dimensional stability. A light 2-way zipper in Metalux design finishes the look.
