Even though our comforters come with a silk or cotton shell, there are numerous drawbacks to use them without proper duvet covers, for example, the shell will get dirty easily, and yet you will not be able to wash the comforter with water since it will destroy the soft and fluffy feel of the silk floss filling inside, not to mention the disruption a bare comforter can bring to your overall bedroom theme.Getting a good duvet cover will solve these problems easily, as silk duvet covers can be machine-washed with water, unlike comforters. A good duvet cover will also complement well with the rest of the room decor. Getting a silk duvet cover to go with the comforter is the best way for one to enjoy the full benefits of the comforter, as duvet covers made from other materials will partly undermine the breathability, the lightweight and hypoallergenic nature of the silk comforter.
