The bearaby woven ones give the weight without the heat retention of the comforters. They originally also had a comforter with a high quality duvet which we have, but it is a beast to move and it is hot. They no longer make them, but there are others.
We have a few of woven ones from over the years…I buy one on sale for the couch, but they migrate to the bedrooms magically and I never see it again. They have held up well. The first one is starting to show some wear.
They say you can wash them, but I have always been afraid to put them in my washing machine at home - I am afraid it would be too heavy.
My husband was horrified by the price, but guess who sleeps under one every night now?? Lol
