D & G The Duck and Goose Co 10.5 Tog King Size Down & Feather Duvet (100% cotton cover)
Product description
The essentials
If you’re shopping for a king size duvet that’s meant to work across the year, this 10.5 tog down & feather design is built around the idea of balanced warmth. The filling is 550gsm of responsibly sourced down and feather, which (on paper, at least) should help with natural temperature regulation rather than feeling either too stuffy or too cool.
It’s also not just about warmth. The cover is 100% cotton downproof fabric, with double-stitched seams and piping that gives it a more finished look on the bed. There’s a premium box-stitch design to help the fill stay where it should, which is the sort of detail that matters if you dislike cold spots after a few nights.
One thing to bear in mind: down and feather duvets can be brilliant, but they can also be a little less forgiving than synthetic fillings if you’re very sensitive to care requirements. This one is machine washable on a cool, delicate cycle and tumble dry on low, but you’ll still want to follow that routine consistently.
Key features worth noting

Where this duvet feels most thought-through is in the combination of tog rating, down-proof cover, and fill distribution.
- 10.5 tog for year-round comfort: aimed at the “middle ground” between summer light and deep winter heavy.
- Box-stitch / even fill distribution: designed to keep the filling spread evenly, reducing the chance of lumpy areas and cold patches.
- Down-proof 100% cotton cover: tightly woven fabric is meant to minimise feathers poking through.
- Premium finishing details: double-stitched seams and piping give it a cleaner, more styled appearance.
It doesn’t claim to be the lightest or the warmest option, and that’s exactly the point. If you tend to run cold or heat up fast, this tog level may land just right—or it may feel slightly mismatched.


What it feels like in everyday use
The practical “test” with a duvet is how it behaves over a week: does it keep you comfortable as the temperature swings, and does it stay evenly filled?

With a 10.5 tog rating, you can expect it to suit typical UK seasons without needing to change the whole bedding set. For example, on an autumn night where the room starts cool but warms gradually, the temperature-regulating properties of down and feather are intended to help you stay comfortable rather than feeling clammy. The box-stitch pattern is also meant to help keep warmth consistent across the bed.

Who it suits (and who should think twice)
It’s a solid pick if you want a king size duvet with a middle-of-the-road tog rating, plus the benefits that come with down and feather—especially if you care about even warmth and a downproof cover.

Worth considering if: You like the idea of natural temperature regulation and want something that can stay on the bed through most of the year. You also prefer a cotton cover and don’t want to compromise on finishing details like piping.


Better avoided if: You’re expecting a duvet that’s ideal for very hot summer sleepers or very cold winter nights—10.5 tog is a balance, so it may feel too warm for peak heat or not warm enough if you’re chasing maximum winter loft. Also, if you’re not keen on following wash and dry guidance (cool delicate wash, low tumble dry), this may be more maintenance than you want.
Care & maintenance
This duvet is designed to be easier to look after than some delicates: machine wash on a cool, delicate cycle and tumble dry on low heat. That’s a straightforward routine, but it does depend on you actually doing it properly.
It’s also wise to keep an eye on how evenly it dries. Even though the box-stitch design is meant to keep fill distributed, wet filling can clump if drying isn’t handled carefully. If you don’t have the space or time to dry thoroughly, you may find it takes longer than you’d like.

Is it worth it?
For many shoppers, this duvet earns its keep because it aims for a practical year-round tog level (10.5), uses a downproof cotton cover, and is built with a box-stitch pattern for more consistent warmth. Add in the fact it’s machine washable and you get a “nice on the bed, realistic to care for” kind of choice.
It might not be the best match if you’re very specific about duvet warmth extremes (either “always freezing” or “always hot”), because 10.5 tog is deliberately balanced rather than extreme. If you prioritise comfort, even distribution, and a cotton cover you can maintain with a standard wash routine, then it’s a sensible buy to track.
