The ERWIN M. Elio is a summer duvet designed to keep you comfortable during warmer nights. Measuring 140 x 200 cm, it features a filling of 90% white new duck down and 10% new white feathers, categorized as Class 1 for its high quality. This filling is encased in a 100% cotton cover with a fine twill weave and elegant satin piping, providing a skin-friendly feel that is typical of hotel-grade laundry. To ensure a healthy sleeping environment, the duvet carries the Nomite certification for mite-proof ticking and the Downpass seal, while the OEKO-TEX® STANDARD 100 certification confirms the materials are safe for your skin. For added safety, the fabric has passed the cigarette glow test. You can maintain the duvet easily by washing it on a gentle cycle up to 60 °C, tumble drying on a low setting, or using dry-cleaning services, though you should avoid using chlorine or bleach.
