The duvet has very good construction materials and indeed you don't sweat at all, but it is heavy. It often slips down during sleep and it is difficult to pull it up to cover yourself due to its weight. And when trying to shake it and spread it out, I can't lift it. I have washed it in the washing machine and it hasn't changed at all.

Very good quality materials....good heat performance without sweating and weighing you down.....cozy....much better than other brands.
