This is my first time buying a hollowfibre duvet after only using down or feather duvets and I am quite happy with the quality. The outer material of the duvet is a good quality white cotton satin stripe and the duvet feels thick. The only negatives (and the reason that it did not receive 5 stars) is because the finish on the edges look a bit cheap. It would have made a world of difference if it was piped.
