The ERWIN M. Star is a luxury-class 4-season duvet designed to provide consistent comfort throughout the year. Measuring 135 x 200 cm, this white bedding is filled with 100% new white goose down of Class 1, ensuring a high level of warmth and softness. The cover is crafted from 100% cotton mako batiste and finished with elegant satin piping for a refined look. To ensure the filling remains evenly distributed, the duvet features body-contouring twill quilting with 2 cm channels that prevent cold spots from forming. The inner cover is Nomite certified, making it both down-proof and resistant to mites, while the entire product carries the OEKO-TEX® STANDARD 100 and Downpass certifications for safety and ethical sourcing. It has also passed the EN ISO 12952-1 cigarette glow test, adding an extra layer of security to your sleep environment. Maintaining this duvet is straightforward as it can be washed at 60 °C, tumble dried on a gentle setting, or dry-cleaned, provided you avoid using chlorine or bleach. This combination of high-grade natural materials and technical certifications makes it a reliable choice for those who value a breathable yet cozy sleep experience in any season.
