The ERWIN M. Elio is an all-season duvet insert designed for year-round comfort in a 140x200 cm size. It features a high-quality filling composed of 90% new white duck down and 10% new white feathers, categorized as Class 1 to ensure an optimal balance of warmth and breathability. The duvet is encased in a white 100% cotton cover with a fine twill weave and finished with elegant satin piping. For added hygiene and durability, it includes a Nomite inner cover that prevents mites and down leakage, while the OEKO-TEX® STANDARD 100 certification guarantees the materials are free from harmful substances. The product also carries the Downpass seal and has passed the cigarette glow test for increased safety. This bedding is well-suited for those who value a natural, breathable sleep environment. Maintenance is straightforward, as the duvet can be washed on a gentle cycle up to 60 °C, tumble dried on a low setting, or professionally dry-cleaned, provided that chlorine bleach is avoided.
