This luxury quilt by Sienna Living features 80% Goose down and 20% Goose feather filling. The higher ratio of down cluster means that this quilt insulates much better when compare to a quilt with higher amounts of feather. When compared to duck down, the goose down cluster size is larger therefore it gives the ability to insulate better. 2 Quilts in one-for all year round comfort. Winter - Clip both quilts together for maximum warmth during the coldest months. Summer - Simply separate one quilt and it becomes ideal for summer. Autumn & Spring - Use either quilt for your individual warmth and comfort. When both quilts are clipped together this quilt is ideal for winter. (Note: 1 blanket weight being summer weight on our scale). All our duck/goose down quilts and pillows use ethically-sourced Australian duck/goose down and feather.
