My new Duvet is WOOLDERFUL !!! I bought the all season (so 2 duvets to combine weather dependent). On unpacking I thought, these are too thin, even both together I'll be cold... Oh how wrong could I be? Started out with the thickest of the two (it's only May) and found I was a little too warm already. Changed over to the thinner one and am soooo comfortable in bed !!! It is so light, it feels so light, like it wouldn't keep you warm at all, but it does brilliantly. I am confident that when winter comes and I combine the two I will be toasty warm, but not weighed down with a heavy duvet like before. Would definitely recommend !!!!
