The ERWIN M. Hypno is an all-season duvet designed to provide consistent comfort throughout the year. It features a filling of 100% white new duck down of Class 1, encased in a 100% cotton fine twill cover with elegant satin piping. To ensure the filling remains evenly distributed and does not shift during use, the duvet is constructed with 2 cm high channels. Measuring 155 x 220 cm, this white bedding includes a Nomite inner cover that is both down-proof and resistant to mites. The materials are certified under OEKO-TEX STANDARD 100 and carry the Downpass seal, while the fabric has passed the EN ISO 12952-1 cigarette glow test for added safety. You can maintain the duvet using a gentle machine cycle up to 60 °C and a gentle tumble dry, though you should avoid chlorine or bleach and may use dry-cleaning services.
