Goose Down Duvet vs Duck Down Duvet

Choosing between goose or duck down is a decision which perplexes many prospective duvet buyers. There are a lot of misconceptions about the differences between down which we hope to do away with. The fact is that goose down provides slightly more insulation than duck down. If there are two duvets of equal size with different down filling, the duck down duvet will have approximately 87% of the insulating power as the duvet made of goose down.

Furthermore, individual tufts of goose down are somewhat larger than the duck equivalent. This is part of the reason for the greater demand for and higher price of goose down.

That said, the overall quality of the duvet matters more than the type of down. A high quality duck down duvet will be more comfortable and last longer than a goose down duvet of lesser quality.


Eiderdown is the most exclusive variety of down, highly sought-after for its unrivaled quality and unique pedigree. Eiderdown is hand-picked from eider duck nests, mostly found in Iceland and Scandinavia, at the end of the breeding season. The eider duck is a wild species which has been protected in Iceland since 1847. Eiderdown is harvested traditionally and sustainably, resulting in a very limited supply and unparalleled prestige.

We stock various eiderdown duvets.

Down Regulations

Back in 2001, European legislation was introduced which mandated that consumers be given clear information about the composition of down duvets. The EN 12934 regulates labelling for fillings made up of either feathers or down.

They are the first and only such labelling regulations that have been developed and implemented by all EU and EFTA states. The EN 12934 norm is applicable to both duvets and pillows, with the labelling required to provide the following information at a minimum:

- Origin
- Colour of the filling
- Proportion of down to feathers expressed as a percentage
- Down quality/class (from Class I to Class V)
--> Class I: only new down and feathers
--> Class II: recycled down and feathers or other stuffing material up to 15%
--> Class III: Percentage of “strange” stuffing may be 15% or more.

The duvets we offer use only Class I down and contain at least 90% down.

Where possible we always mention the fill power of the down in our duvets. This is the only objective measurement of down quality.

Read more about the fill power of down or go to the EDFA website if you want to read all about the EN12934 regulation.

What is Down

Down is a layer of fine feathers, found under the tougher exterior feathers of the birds. Down is an excellent thermal insulator used in goods such as jackets, bedding, pillows and sleeping bags. Rather than quills, a down cluster has a round centre called a plumule. Soft and airy, down has thousands of tiny fibres that radiate from its core. This provides an even amount of warmth across an entire surface area and is one of the main reasons why down is considered greatest of all duvet fillings.
