This comforter (aka duvet) is made with microfiber fill. Microfiber is soft and plush. It's a high quality polyester that's meant to mimic the softness of down. The shell is 300 thread count cotton, which is soft and quiet. This comforter is generously filled. Microfiber doesn't have the same insulating properties as down, so microfiber comforters are heavier weight. We need a fair bit of fill to achieve the desired warmth. One benefit of a synthetic comforter is that it can be machine washed at home, given your machine is quite large and you wash/dry on a low heat setting. Natural down and feather are quite sensitive to moisture, but polyester is not! This comforter comes in All Season Weight, which works well for room temperatures around 60 – 65 degrees F or if you’re fairly cool when you sleep.
