Made of soft combed superwashed pure new Merino wool. Provided with zip. The pillowcase made of soft, warm and precious Merino wool is the best contact surface for your head. The pillowcase can hold a considerable air mass inside the top layer of its fibres, absorbing excess moisture and sweat and creating an ideal microclimate and temperature with no overheating. The lanolin inside the fibres has an important preventive and healing effect on the rheumatic pains of the neck and cervical area.
