The ERWIN M. Star is an all-season duvet designed to provide consistent warmth and comfort throughout the year. It features a filling of 100% white new goose down from Class 1, weighing 600 g, which is encased in a 100% cotton mako batiste cover finished with elegant satin piping. To ensure an even distribution of warmth and prevent cold spots, the duvet is constructed with 2 cm quilted channels. For added hygiene and protection, the inner cover is made from Nomite material, which is both down-proof and mite-proof. The product carries the Downpass and OEKO-TEX® STANDARD 100 certifications, confirming its quality and safety. It has also passed the EN ISO 12952-1 cigarette glow test for enhanced safety. You can maintain the duvet by using a gentle wash cycle up to 60 °C, tumble drying on a gentle setting, or through dry cleaning, though you should avoid using chlorine or bleach.
