Fill power and down content describe different things
Fill power describes loft under specified test conditions: how much volume a given amount of down occupies. It is different from the percentage of down in the filling. A down-content percentage describes composition, not the total quantity of fill or a finished duvet's temperature rating.
Compare fill-power measurements on a like-for-like basis. Test method and conditioning matter. A product's species label cannot replace the stated measurement, and a higher number alone is not a promise of a particular sleeping temperature.
Compare fill weight within the same size
Fill weight is the amount of filling in the duvet, usually shown in ounces or grams. It is separate from fill power. A larger duvet can contain more down simply because it covers a larger area; compare the same size and construction when judging warmth options.
Read all of the selected variant's information together: species, down content, fill power where stated, size and fill weight. Your bedroom heating, other bedding and personal preference also affect how warm the bed feels.
Check construction and fit as well as the filling
Baffle-box construction uses internal fabric walls to form compartments for the down. Check the construction, shell material, dimensions and care instructions on the actual product, rather than treating every goose or duck down duvet as equivalent.
A duvet insert provides the filling and warmth. A duvet cover is the separate outer layer. If you want both, check a set's included pieces and match the cover and insert dimensions.
Which should you buy?
Start with the warmth and dimensions that suit your bed, then compare the price and specifications of the goose and duck down options available in your market. If both meet your needs, budget and the details of the specific products can guide the choice. Avoid choosing a heavier option solely because it sounds more premium.
CloudWeave's product pages show the currently available size and warmth choices. Review the selected variant before ordering; availability, fill-content options and pricing can differ between the United States and Australia.
Frequently asked questions
Does goose down always mean a warmer duvet?
Species alone does not determine a finished duvet's warmth. Compare down content, fill power where stated, fill weight, size and construction for the specific products. Choose according to your room and sleep preferences.
Compare goose and duck downHow should I wash a CloudWeave duvet or custom cover?
Follow the care label supplied with your specific product. A down insert and a printed polyester cover can have different care requirements. Do not apply one item's washing or drying instructions to the other; ask support if the label is unclear.
