I bought it when it was really cold in Dallas, but by the time I got it washed for use, it was already getting warm. I couldn't wait until next winter and started using it anyway. I used it over my light weight down comforter and they were a perfect combination - not too warm and not too cold. It is definitely thicker than my 600ct duvet cover. It is a bit crinkly right now, but I know it'll soften up after a few more washes. All in all, it was a great deal and I'd buy it again.
