Our all-season comforter comprises ultra-natural goose duck down feathers and 100% cotton fabric. It is soft and breathable and gives you a sound sleep experience. The filling of the down comforter is 95% waterfowl feather 5% down, which has a high degree of fluffy and keeps warm all the time. Four corner tabs are very convenient for attaching a duvet cover and protecting the comforter from shifting. The longer you use it, the more comfortable and fluffy our luxury feather-down comfort will become, and the crunch of the feathers will disappear; there will be no feathers poking you and no odor. Hurray!
