The duvet is a very soft, lightweight tuft made up of countless, extraordinarily fluffy “barbs” that make it three-dimensional. The down is able to retain air, thus creating a soft isolating embrace around the body. The duvet is the ideal cover for every comfort need, appreciated in every season and in every latitude. His original function is to protect the birds body and to permit the perspiration, keeping at the same time the correct microclimate of the bird´s body. That´s why we often speak about the famous thermal shield of the birds. The most important characteristics of a DaunenStep duvet are the 100% natural down filling and the 100% natural cotton fabric.
