The shell fabric of the comforter is a very stiff polished cotton and even enclosed in a heavy duvet cover with even the slightest movement it was very noisy.  I probably could have gotten used to it if the comforter had lived up to its warmth claims. It never seemed to trap the heat properly and I wasn't able to get warm. Mid-way through the night I removed it and put back my very old (mostly feather dust now) down comforter and was warm in seconds. I returned it and ordered down.

Pros: Nicely stitched and filled
Cons: Not warm and very noisy
