Made with 100% European supreme goose down which is wonderfully light, soft and warm. The large and lofty clusters of pure down offer exceptional insulation. The Nomite™ mark means this duvet is suitable for people with dust mite allergies. Warmth without weight Down has a naturally airy and open structure that traps heat, so it gives excellent insulation while being much lighter than feathers. This means you feel perfectly warm, without being weighed down. 3D Pocket Construction This duvet is sewn to create evenly divided square boxes. This means the down, feather or mixed filling is evenly distributed, so you enjoy warmth without cold spots. Products labelled with the DOWNPASS logo guarantee high quality and the certainty that down and feathers used as filling material are ethically sourced and come from tightly controlled and traceable supply chains. In addition, the quality of all products is monitored by independent testing institutes. Responsibly sourced The feather and down used is certified to ensure high animal welfare and full traceability from farm to product. All of our natural bedding suppliers provide us with assurance that their feather and down is sourced only as a by-product. In addition, they're monitored to ensure they practice the highest standards of animal welfare.
