The Pillowtex® Dream In Color All Season Comforter is filled with PF620 which is a newly created material that is the closest to down, but better! PF620 fiber balls are fluffy yet maintain the shape and create a shape like down. The soft polyester clusters make the comforter hypoallergenic, breathable, and extra fluffy. The baffle box construction keeps filling in place. The corner loops make it easy for you to put a duvet cover over the comforter.
