What is an Ultralight Icelandic Eiderdown Duvet?

 It is our lowest-fill eiderdown duvet: 80 g/m² of pure Icelandic eiderdown, designed for bedrooms around 22–24°C / 72–75°F, warm sleepers and warm climates. It gives less insulation than our Light, Medium and Warm fills while keeping the softness and low weight of eiderdown.
