The ERWIN M. Star is a versatile four-season duvet designed to provide consistent comfort throughout the year. Measuring 140 x 200 cm, it features a filling of 100% white new goose down from Class 1, which ensures a high level of warmth and breathability. The exterior is crafted from 100% cotton mako batiste with elegant satin piping, while the interior utilizes a Nomite cover that is both down-proof and resistant to mites. To ensure the filling remains evenly distributed, the duvet employs body-contouring twill quilting with 2 cm channels that adapt to your shape during sleep. For peace of mind regarding safety and quality, this bedding has passed the EN ISO 12952-1 cigarette glow test and carries both Downpass and OEKO-TEX® STANDARD 100 certifications. You can maintain the duvet by washing it at 60 °C and tumble drying it on a gentle cycle, though chlorine bleach should be avoided.
