Merino Wool is a natural fiber grown by Merino sheep and, since it’s thinner than regular wool, it feels softer on your skin and is more comfortable. Our yarns measure 19.5 microns in thickness: it's a fine and strong material with a silky feel to the touch. Merino wool is breathable and it keeps you warm and fresh depending on your body temperature, thanks to its thermoregulation property. It doesn't hold on to unpleasant odors and it can hold up to 33% of its weight in moisture, leaving the surface comfortably dry. The Merino Wool Zipped Cardigan
