Filled predominantly with duck down, this lofty duvet offers a lightweight warmth. Its 100% cotton cover delivers a soft, naturally breathable feel to keep you cool and comfortable throughout the night. 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. Suitable for Regular Washing Washable at 40°C, allowing for an effective clean that's much kinder to the environment. 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. Nomite™ This allows people with dust mite allergies to enjoy natural bedding. Following a hygienic washing and high-temperature drying process, fillings are then sealed in a tightly woven fabric cover which acts as a barrier against dust mites. All of our natural bedding suppliers provide us with a guarantee that their feather and down is sourced only as a by-product of the food industry. In addition, they're monitored to ensure they practice the highest standards of animal welfare. Find out more about our animal welfare policy . The box packaging of this product is fully recyclable. It contains material originally delivered to us as transit packaging, which we've recycled, here in the UK, to make into a new box for your duvet. Have you thought about a new pillow? Shop here .
