Both duck down and goose down are natural fillings that give you that soft, fluffy, cloud-like feel a synthetic duvet cannot match. The question is whether the price gap between them is worth it, and whether the difference in feel and warmth is genuinely noticeable for most sleepers.
This guide walks through every part of that decision honestly, so you can spend your money where it actually matters.
What Is Duck Down?
Duck down is the soft, fluffy undercoat from underneath the outer feathers of a duck, found mostly on the belly and chest. It has no quill and no stiff structure. The clusters look like tiny dandelions, and they trap air in small pockets, which is what gives duck down its insulating power.

Duck down is the more widely available of the two natural fills. Most ducks are smaller birds with shorter lifespans than geese, so the down clusters they produce are smaller too. This affects how warm and lofty the final duvet feels, but it also keeps the cost lower.
What Is Goose Down?
Goose down is the same kind of soft undercoat, but taken from a goose instead of a duck. The clusters are larger, denser, and more uniform because geese are larger birds and live longer than ducks. That extra size and maturity makes a real difference in the finished duvet.

The premium versions of goose down come from colder climates. Hungarian, Polish, Canadian, and Siberian geese produce the most sought-after down because the cold conditions force the birds to grow thicker, fuller clusters for insulation. Hungarian white goose down sits at the top of most ranges.
Which Has Better Fill Power and Insulation?
Fill power measures how much space one ounce of down occupies. Higher fill power means lofter, fluffier clusters that trap more air with less material. It is the single most useful number when comparing down quality.
Duck down typically sits between 500 and 700 fill power. Goose down ranges from 600 up to 900, with premium options well above that. The larger clusters produced by geese hold more air per gram, which is what gives goose down its edge on insulation.
In practical terms, a goose down duvet at the same tog rating as a duck down one will use less fill to deliver the same warmth. That makes it lighter on the bed while still keeping you just as warm.
Is Goose Down Warmer Than Duck Down?
Gram for gram, yes. Goose down has roughly 15 percent more insulating power than duck down at the same cluster size, and the clusters themselves are larger to begin with.
What this means in real life is that a goose down duvet feels lighter for the same level of warmth, or warmer for the same weight. At identical tog ratings, both will keep you equally warm. The difference shows up in the feel rather than the temperature.
For very cold bedrooms or sleepers who feel the cold easily, goose down delivers warmth without the heaviness. For most UK households, the warmth difference is hard to notice if both duvets are at the same tog.
How Does the Feel and Loft Compare?
This is where the gap is most noticeable.
Goose down has higher loft. It puffs up more, drapes more naturally around the body, and feels distinctly lighter and more luxurious to lie under. The larger clusters mean more air inside the duvet, which produces that cloud-like floating sensation premium bedding is known for.
Duck down feels softer than synthetic fills and lighter than feathers, but it has less natural loft than goose down. Duck down duvets often need a bit more weight in the fill to reach the same warmth, which makes them feel slightly heavier on the bed.
If you have ever stayed somewhere that had genuinely premium bedding and noticed the difference immediately, that is goose down doing its work.
Which One Lasts Longer?
Goose down lasts longer, and it holds its loft better over years of use.
The larger, denser clusters in goose down resist compression and clumping better than duck down. A high-quality goose down duvet can last fifteen to twenty years with proper care, regaining its loft after every shake and continuing to insulate effectively.
Duck down typically lasts eight to twelve years before it starts to lose loft. The smaller clusters break down more quickly under the weight and warmth of regular use. It is still a long-life product compared to synthetic alternatives, but it does not match goose down on longevity.
Why Is Goose Down More Expensive?
Three reasons.
First, geese produce less down per bird than the volume of duck down available, because there are simply more ducks farmed worldwide for the food industry. That makes duck down more abundant and therefore cheaper.
Second, the premium varieties of goose down come from older, larger birds in colder climates, which take longer to mature. That extra time means a higher cost per bird.
Third, goose down has objectively higher fill power, longer lifespan, and better loft. You are paying for genuinely superior performance, not just a different label.
The gap is real, but so is the value. A goose down duvet costs more upfront and lasts roughly twice as long as a duck down equivalent, which evens the maths out over time.
Which Is Better for Allergies and Sensitivities?
Neither natural down is ideal for severe allergy sufferers. Both can carry traces of natural proteins that trigger reactions in sensitive people, and both can develop dust mite issues if the duvet is not maintained properly.
For people with mild sensitivities, well-treated goose down is generally the safer choice. The cleaning process used for premium goose down is more thorough, and the higher quality covers used with it have tighter weaves that block more allergens.
For anyone with serious allergies, neither natural down is the right answer. A down alternative duvet is the simpler solution and removes the risk entirely.
Which One Should You Choose?
If feel and longevity matter most and you have the budget, goose down is the better choice. The loft, the drape, and the warmth-to-weight ratio are all noticeably better. Over fifteen years of use, the price difference works out fairly even.
If you want the natural fill experience but at a more accessible price, duck down delivers most of what makes natural down great without the premium tag. The feel is still significantly better than any synthetic, and the warmth at the same tog is identical.
If you sleep cold, in a cold bedroom, and want the lightest possible duvet that still keeps you warm, goose down is worth the upgrade. The lighter weight at the same tog is genuinely noticeable.
If budget is the main factor, duck down still gives you a luxurious natural feel that synthetic alternatives cannot match.
Rohi Home Options in Duck and Goose Down
Our duck feather and down range is the practical entry point into natural fills. The duvets in this range combine duck down for softness and duck feather for structure, giving you that natural feel at a more accessible price.
For goose down, we offer both goose feather and down and Hungarian white goose feather and down options. The Hungarian goose range sits at the top of our line for natural fills, with the loft and warmth-to-weight ratio that goose down is known for. Both ranges cover standard UK tog ratings and bed sizes.
Whichever direction you go, all our down options come with the same construction standards and the same long-term performance you would expect from a properly made natural fill duvet.
Frequently Asked Questions
Is goose down better than duck down?
For loft, warmth-to-weight ratio, and longevity, yes. Goose down clusters are larger and produce a lighter, fluffier, longer-lasting duvet. Duck down still outperforms synthetic alternatives but does not match goose down on these specific qualities.
Is duck down warm enough for winter?
Yes. A good duck down duvet at 13.5 or 15 tog will keep you warm through any UK winter. The difference between duck and goose down at the same tog is in feel and weight, not in warmth.
Why does goose down cost so much more?
Goose down is rarer, produced by older and larger birds, and has higher fill power and longer lifespan than duck down. You are paying for a genuinely better product that lasts longer.
Can I tell the difference between duck and goose down?
Most people can. Goose down feels noticeably lighter and lofter, with more drape around the body. Duck down feels softer than synthetic fills but with less of that floating, cloud-like quality.
Is one better than the other for allergies?
Both are natural fills and both can trigger reactions in sensitive people. For severe allergies, neither is ideal and a down alternative is the simpler choice. For mild sensitivities, well-treated goose down tends to be processed more thoroughly.
Duck down and goose down are both excellent natural fills. Goose down is the premium option for feel, loft, and longevity, while duck down delivers most of the same natural benefits at a more accessible price. Explore our full down duvet range below.
