Wool is a natural material known for its thermal qualities, softness and fluffy look. In cold weather, wool retains heat, and on warm days it absorbs sweat, making it a good choice no matter the season. Wool lets the skin breathe and preserves its power to insulate when wet, always maintaining a stable body temperature.
