I purchased this duvet for my grandson's room and he told me he was really warm the other night when he slept over.  I'm impressed with the quality, the duck and goose filling and just how it feels like really good quality material.  When I first received it, it seemed a little flat, but all I did to fluff it up a little after being packed so tightly, was to throw it in the dryer on low with some dryer balls.  Perfect!!!!
