I bought this 4 seasons duvet for changing my other quilt of another well-known brand so I wanted to try this brand there is also French production, then this quilt is just as comfortable and smooth as the D mark ... there are 2 separable duvets (1 200 gr + 1 300 gr.) so for now I use the quilt 300g as it is hot and swelling so I have to try again 2 attached but tied for there is a string in the 4 corners very easy to gather and to spare. duvets are very comfortable and soft and light. Frankly if you have a 4 seasons duvet, you can buy eyes closed without any problems. Thank amazon for their quick and careful delivery.
