The double duvet blanket by Das Home is externally made of synthetic fabric, which is durable and does not wrinkle easily. Its filling is made of hollowfiber, a synthetic material with gaps in the weave that allow the duvet to breathe, making it lightweight and fluffy. The difference between a duvet blanket and classic duvets is that it combines the properties of both a duvet and a blanket, offering a softer and warmer sleeping experience.
