A duck down duvet provides optimum thermal comfort all year round and comfortably envelops each sleeper for a unique sleep experience. A precious, airy and voluptuous material, duck down is a historic ingredient in duvets. Its lightness and calorific value provide a refined and comfortable cover, for quality nights and a deep sleep. Popular with 5-star hotels and palaces, duck down duvets are a must-have for top-of-the-range bedding.
