The Ladies Thermo Pants The Kilpi Knob is a seamless thermal stretch fabric made of a functional, very comfortable and quick-drying OPTI-DRY material. It reliably evaporates moisture and sweat and keeps you dry all the time. They have a reinforced section in the knee area and a flat rubber at the waist that you will not even know about during the sport. It is suitable for mountain hiking and in cold conditions where you get busy. However, they will do good service in any physical activity, both as a lower layer and as a single upper layer.
