Impressed: great insulation and breathability, better than down
After much pondering I ordered one of these wool duvets for use in my camping car before a January trip to the Scottish Highlands. I knew the weather was going to be bitterly cold so was looking for something snug but which wouldn't be too affected by damp when used in a cramped vehicle with inevitable condensation. Used inside the uninsulated, unheated camping-car in a damp -2°C I was very pleased to find the heavyweight wool duvet kept me warm all night and on the few milder nights, it still wasn't sweltering and I never woke feeling overheated or sweaty - as I can with my previous down duvet which can cause over-heating. I found the wool duvet feels chilly for the first few minutes but then seems to trap and reflect body heat providing and maintaining body heat through the night. At home I use an electric blanket to air my bed before use so this isn't an issue and it feels warm to slip into. As per the instructions, I aired the duvet thoroughly for a few days before use to reduce the sheepy-smell thinking it might be quite overpowering in a very confined space but there was only a very light and mild smell which was barely noticeable and, as an outdoorsy person used to sheep, was actually quite homely. On arrival home, I was so pleased with the performance of the heavyweight duvet in cold damp conditions that I ordered a second in mediumweight for use at home. Both duvets are well made with a thick cotton cover although the single/heavyweight duvet had better finishing with edging over the hem rather than a plain stitched hem as on the king size/mediumweight duvet. The wool seems to be a continuous length stitched into baffles running along the width (or length - depending on how the larger versions are draped over the bed) rather than smaller squared baffles with loose wool fibres similar to a down duvet. This completely eliminates the need for any shaking to redistribute the content. The wool duvet feels heavier than the down duvet I am used to but it is a pleasant feeling as it folds around the sleeper in a similar way to a weighted blanket but without feeling oppressive. The tog ratings are 7-9 togs for the mediumweight and 10-12 togs for the heavyweight, not 10-14togs as stated on the listing. For additional information the filling is 375gsm on the mediumweight and 550gsm on the heavyweight. The duvets live up to their promises, are warm, breathable and very snug. I have always preferred natural materials and insulation and previously thought down was unbeatable but having tried wool, it definitely has the edge for temperature regulation.

Better than synthetic
A great duvet cover that is natural wool filed giving better breathability in the summer and warmth in the winter. I much prefer it to a synthetic duvet and think it was a very reasonable price.

Once you try wool you won't go back
The things we do for our loved ones, right? Here I am, a happily married man plodding his way through life and kipping each night under a comfortable duvet when my wife says "we should get a wool filled duvet". What? Why on earth would I want a wool filled duvet? I run hot during the winter for goodness sake the last thing I need is to be essentially wearing a woolen jumper to bed everyday! "Oh, but wool keeps you cool and warm" says the wife. Yes, of course it does I think... But guess what... I still buy one! I am glad I did! As I write this we've had some chilly weather in blighty and I have slept like a log, comfortable, warm but not hot and haven't woken up feeling like I've been sweating more than I do when thinking about paying the utility bills! The duvet itself has good a decent weight to it, enough to notice but not enough to feel like it is too much. There is a thickness to it which provides a great look when plumped up in a cover and feels generally well made. Our previous duvet was man-made-fiber and had moved within the cover, this is stitched in such a way that leads me to believe that shouldn't be an issue. Both my wife and I are very pleased to have swapped to a wool duvet, it warms up much quicker and offers a far better sleep then before, the best thing being that my wife, who usually runs cold, no longer feels the need to put cold feet on me to warm up - the duvet is doing it for me! The only downsides would be that, with it being a naturally filling, you will notice the smell of sheep on the duvet for a day or two, this is solved easily by airing it outside of hanging it up in a garage - personally, we weren't bother by it but some might be. The other being the noise the duvet makes, when new it can sound like a crisp packet being ruffled, again we didn't find it an issue and it never disturbed our sleep, we have found that after a week or two it has settled and put this down to the cover becoming softer over time, give it a good shake each day and it'll improve. In summary, I won't go back to another type of duvet, whilst I am yet to try this during summer temperatures, having gone back to a poly-filled duvet for a night when away for work, the different is incredible and one that is difficult to describe unless you try it yourself, you to may be as surprised as I am! I might even get an extra one for the guest bedroom for when the misses is snoring and I need some peace...

A good all year-round duvet with minor imperfections
Bought the medium-weight one and it's not very thick but heavy and really warm, good for winter, especially if you have a fluffy duvet cover. You can replace a thinner duvet cover for other seasons, and a medium-weight duvet can be used all year-round. The only issue I noticed was that it crackles when moved like a plastic bag, which can bother some people.

Very pleased :)
Extremely pleased with the quality of this duvet. I actually found the sheepy-lanolin smell very reassuring when I unwrapped it as it is much better than it smelling of nasty chemicals. I left the duvet to air for 48 hrs before using and now it hardly smells at all. The cotton cover is a very high quality, which I'm confident will keep all the wool safely contained inside. It only produces a slight rustle when moved, which reminds of the sound and feel of a high quality down duvet I used to have. It is actually a lot thicker and fluffier than I expected for a medium weight duvet. I've been sleeping in only a cotton sheet lately due to the hot weather so I was expecting to cook under the duvet the first time I used it. Surprisingly I slept very well and only woke up once. The duvet feels luxurious and cozy to lie in but also airy and breathable. I'm wondering if the reviews claiming it is too hot were maybe using synthetic or polycotton duvet covers. Using 100% cotton (or another breathable natural fibre) duvet covers and bed sheets will allow the wool to breathe properly. I'm also confident it will keep me warm and toasty in the winter months. I feel like I've grabbed a real bargain here, and it is great that it is manufactured in the uk using British wool.

Cosy, light and airy
I bought this and have been very impressed with it cosy , no weird smell and light and airy sleeping well with it, at first I thought of returning it as I didn’t feel it would be possible to keep warm with something so lightweight but I tested it and was very impressed, I’ve always suffered with heat regulation as I have a medical condition that’s affects my pituitary gland and also lots of other conditions that affect my musculoskeletal body and osteoarthritis on top of that, sleeping has been a nightmare for yrs lots of medication hasn’t/doesn’t work but I have honestly been able to sleep a little better with this natural fibre duvet so the claims about pure wool helping rem sleep must be true, I was so happy I kept the duvet and ordered another heavyweight king size version to change when it’s really cold sub zero temps, both duvets are amazing and the little rustling noise is minimal and doesn’t bother me, I’m more reassured that it’s the pure cotton cover and no nasty synthetic chemicals in my bedding , the price for these duvets were fantastic compared to other manufacturers and the are still made here right in the uk with all certified pure British wool , once you try wool you probably won’t ever go back to synthetic

Very light - Perfect
Perfect. Only just taken into use with hotter weather. A big improvement on the feather duvets. Is a bonus in the hot weather. Would thoroughly recommend.

I love writing a positive review.
Buy it. I am all over the place at the moment, freezing feet, night sweats, hypersensitive.. all the joys of being an over 40yo, female, neurodivergent. I never knew I could be this comfortable in bed. Even before I hit peri-menapause I struggled with controlling my body temperature. Not with this! I recommend it for every man, woman and child. I will never use anything other than a wool duvet again. Don't ruin it with plastic covers, 100% cotton works. I'm super sensitive to.. well.. everything. If I get my nose right into the duvet for a good whiff, it does smell a little sheepish, but I can't say I'd of noticed had I not read the other reviews and purposely gone in for a lung full. I hope the price stays reasonable so people will stop buying cheap plastic duvets, like I did before knowing this existed.
