The ERWIN M. Elio is an all-season duvet designed to provide consistent comfort throughout the year. It features a high-quality filling composed of 90% new white duck down and 10% new white feathers, categorized as Class 1 to ensure a light yet insulating feel. The 240 x 220 cm cover is crafted from 100% cotton in a fine twill weave, finished with elegant satin piping for a refined look. To ensure a healthy sleeping environment, the duvet includes a Nomite inner cover that prevents mites and down leakage, and it carries the Downpass seal and OEKO-TEX® STANDARD 100 certification. For added safety, the materials have passed the cigarette glow test according to DIN EN ISO 12952-1. You can maintain the white fabric by washing it on a gentle cycle up to 60 °C, tumble drying on a low setting, or using dry-cleaning services, provided no chlorine or bleach is used.
