With this four-season duvet, you can sleep comfortably under the wool all year round. All our products are made from 100% merino wool, offering a delightful sleep comfort! Mold formation in wool duvets is virtually impossible. Because wool contains lanolin, it is self-cleaning, antibacterial, and dirt-repellent. Pure merino wool in a bed is not a pleasant environment for dust mites, as wool ventilates optimally and regulates temperature and moisture levels. If you ensure your duvet is regularly aired, dust mites don't stand a chance. Properties: Breathable Moisture-regulating Natural Anti-allergenic Contains no chemical or synthetic blends. Material: Filling: 100% merino wool Cover: 100% cotton Maintenance: Shake weekly and air regularly. Washing instructions: Wash at max. 30 degrees with a wool detergent or a liquid detergent.
