The Erwin M. Star is a luxury-class four-season duvet designed to provide consistent comfort throughout the year. It is filled with 100% white new goose down of Class 1, which offers high thermal regulation to keep you comfortable regardless of the season. The filling is encased in a 100% cotton mako batiste cover featuring elegant satin piping and a white finish. To ensure the down stays securely in place, the duvet uses a body-contouring twill quilting pattern with 2 cm channels. The inner cover is Nomite certified, making it both down-proof and resistant to mites. For added safety and quality, the product has passed the EN ISO 12952-1 cigarette glow test and carries the OEKO-TEX STANDARD 100 certification. Measuring 160 x 210 cm, this duvet is suitable for those seeking a high-standard sleep environment and can be maintained through dry cleaning or machine washing at 60 °C followed by gentle tumble drying.
