LightWool consists of soft and lightweight wool garments specially designed for the warmer parts of the year or to be worn closest to the skin. Did you know that wool has a naturally cooling effect when it's hot outside? Wool insulates against external heat and keeps you cool during warm days. These garments, made of 100% merino wool, ventilate and regulate body temperature based on activity levels. Guaranteed itch-free. Wool naturally resists odor and bacteria, often only needing to be aired out for reuse.
