Very warm
After dry-cleaning our down comforter for the thousandth time (thanks to living with 2 dogs and an elderly cat) and losing even more feathers, we decided to replace it with a down alternative. We use this inside of a duvet cover so I can't speak to the softness, but it is very warm! It seems to be well made, and the filling is evenly distributed across the comforter. So far, so good!
