Supremely comfortable and impressively durable, this Turkish duvet cover blends two of the world's finest fabrics: organic cotton and EUROPEAN FLAX ® linen (the highest grade of linen available). Along with being a highly sustainable fiber, flax linen is lightweight and breathable and becomes softer over time. The charcoal grey front of the duvet cover is accented by a cotton percale backing for comfortable slumber throughout every season. Pair with the coordinating pillow shams for a harmonious look.
