Impossibly light, voluminous, and warm, the Arkthis Winter Duvet is as close to sleeping with a cloud we've ever felt. Crafted using 100% wild Arctic duck down encased in a tight French batiste weave, this luxury quilt has excellent heat regulating properties that warms while wicking moisture away from the body. Its cassette construction and inner bridge ensures warmth is evenly distributed for deep, regenerative sleep. OEKO-TEX-certified, this duvet is finished with a narrow, double-stitched flange. The Arkthis comes with a zippered dust bag for safe storing in the summer months.
