It really does its job, which means that for winter, it is indeed a very warm duvet. As a "disadvantage," I can only mention something that is a result of its advantage, namely that because it is warm in the cold, you don't want to get out of bed. If you are sensitive to the cold, it is just what you need to sleep warm and comfortably.

Excellent Greek-made duvet. In a room without heating below 16 degrees Celsius, you don't feel the cold, you snuggle up until the final drop.

With an external temperature of 7-8 degrees Celsius and rain, it kept us very warm. We are also waiting for winter to have a complete opinion.
