This down alternative comforter is a game changer for me!  I slept so good with it and it was not overly heavy. 
This comforter is a 100 polyester shell covering that is stuffed with 100 polyester fill that mimics the loft and insulation of luxury down. There are loops on every corner will help keep duvet cover in place and the baffle box construction will keep it fluffy and evenly distributed. This is a great all-season, and ultra-warm comforter, this is perfect for all-year round warmth without being overly heavy. 
Easy to care for in large capacity washer and dryer. I gently fluffed mine out of the box by putting it in my dryer for 20 minutes before putting on my bed.
