This is insanly hot for a 10.5,we cannot use it.Affitionally and more a permant problem is that it is a very crinkly cover - i didn't think there was such a thing as a noisy duvet until now. Annoyingly our bed was delayed so had this in the box for months before opening or i would have returned as soon as i opened and realised it was going to sound like sleeping under tin foil.
