You buy a duvet "four season", and in fact you receive two quilts: a fine and average, tied together by snaps. The system is very convenient and allows multiple combinations to fit your notion of comfort.
The cotton cover is of good quality, the down filling is satisfactory: it is not the thinnest down we could find, but still comfortable.
Please note: the quilt is compressed to fit in the package: when you get out it will have a very flat appearance rather disappointing. Rest assured: the feathers will resume in a few days the swelling louse find a cozier look.
The current price, less than 100 euros, really excellent for this handset with two duvets.
