Wool duvet, worth the investment?

[Stumpedasatree]

Thinking of getting one to beat the cold a little this winter. Please let me know any recommendations and your thoughts if you have one?

I love my wool duvets! I bought summer/winter ones (the type you popper together to make one big duvet) about 10 years ago (I think from Woolroom) and they're still going strong.
Lovely and warm in winter but I never get overheated and sweaty, as I can with polyester ones.
I recently upgraded to wool pillows from Baavet too, the ones with zips so that I can adjust the amount of filling. They're very cosy and comfortable. There is a slight sheepy smell but I really like that!
