Just a note that even “washable” wool isn’t going to mean you can do whatever you want and it will specify exactly the types of washers and cycles that it is safe with and you still have to air dry it.

I went with a camel wool comforter here. Mainly due to being washable and cheaper than many other options I looked at. I have an organic cotton duvet cover from I believe Boll & Branch but I could be mistaken on that. I also got their organic cotton sheet set and pillow covers.

My only complaint is I don’t love the whole duvet + duvet insert deal. Mine does have ties on all four corners and they work but I think it they should make it with 6 or 8 ties instead (I had a weighted blanked that was like this and was great) and I also would rather have a zip up duvet cover like the ones from AllergyCare or The Company Store instead of just button up however the former one apparently doesn’t have any ties inside at all and I am unsure about the latter as a reviewer said it didn’t but an FAQ said it did and neither of them offer colors which sucks because I have little interest in white or unbleached cotton colored bedding.
