A combined duvet offering a winter/summer/all year round option which is really useful. The description doesn’t really explain this when browsing, it was only because the picture had two duvets rolled up and a feedback comment from another customer mentioning the three tog option that I knew this is what I was looking for.. I decided to update my duvet having had the same one for years and there’s quite a difference in quality to slightly older duvets - warmer, softer in texture, lighter in weight plus it feels and looks fuller, therefore filling out the cover so the bed now looks well made. 👍
