The ERWIN M. Hypno is an all-season insert duvet designed to provide consistent warmth and comfort throughout the year. It features a high-quality filling of 100% white new duck down of Class 1, encased in a 100% cotton cover crafted from fine twill with elegant satin piping. To ensure the filling remains evenly distributed and doesn't shift during use, the interior is constructed with 2 cm high baffle channels. For added hygiene and durability, the inner cover is Nomite certified to be both mite- and down-proof, while the entire product carries the Downpass seal and OEKO-TEX® STANDARD 100 certification. Measuring 240 x 220 cm, this white duvet is built for safety and ease of maintenance, having passed the EN ISO 12952-1 cigarette glow test and supporting a gentle machine wash cycle up to 60 °C, as well as gentle tumble drying or dry cleaning.
