Comfort Wool men's boxers are the best everyday underwear for active and discerning customers. The outer layer is made of soft, very thin 100% Merino sheep wool. Since the wool is highly elastic, it does not restrict movement and adapts perfectly to the body, allowing you to choose other clothing freely. The combination of natural fibers and polyamide, along with the two-layer seamless construction, provides unique thermoregulating properties while ensuring maximum comfort. The underwear helps maintain a constant body temperature and protects the body from cold and overheating. The product has been dermatologically tested, causing no irritation or sensitivity.
