Both in the lowlands and the mountains, in winter and in spring, you can sleep under a duvet in the utmost comfort.
It is precisely the vital thermoregulation function that allows birds in general - geese and ducks in particular - to withstand a temperature range of 60°C (from -20°C to 40°C) without ever changing their outfit. The thermal insulation capacity of a duck or goose down feather exceeds that of sheep wool by 80% and synthetic fibre batting by more than 100%.

As a consequence, a pure-quality duvet covering weighs 2 or 3 times less than that of a wool or synthetic fibre blanket of equal thermal insulation. Thus, sleeping under a duvet ensures the sensations of well-being and physiological comfort reach extremely high levels.
As with imports, mainly from China and other Asian countries, no specific legislation exists to this regard, meaning that it is possible to find a product labelled a "duvet", but which in reality is not and most importantly, does not have the required characteristics. Increasingly, chicken feathers are mixed with a little down to be used for stuffing, leading to the unmerited label of down

Feather stuffing
Down stuffing

Down derives exclusively from waterfowl animals (goose or duck) and is the most noble and valuable part of the plumage. A small percentage of plumule or small feathers in the stuffing have the task of maintaining the elasticity of the product with their thin rachis.
Their presence in no way compromises the principal characteristics of the hygroscopicity and insulation that will be described below..

The down feather looks like a tuft with a central core from which branch off several silky filaments that are particularly voluminous, resistant, soft and elastic. The tuft is capable of absorbing the air, creating a thermal insulation that maintains body temperature at a constant.
The highest quality of Plumage items is determined by the exceptional volumetric rendering of the tufts (filament dimension and richness) that confer the softness and lightness (filling power) of the product. The stuffing can be made with varying percentages of pure down and small feathers, with the source, the feed, the age of the animals and the geographical location of the farms making all the difference.

The particular characteristics of the down feather are:

  • Insulation: it possesses a great capacity for heat retention, acting as thermal insulation by creating a barrier that, on the one hand, prevents the dispersion of body heat and, on the other, prevents impedes air from coming into contact with the skin.
  • The transmission of the water vapour (hygroscopicity): down feathers have the capacity to absorb moisture produced by the natural transpiration of the sleeper's body (approximately 0.2 litres per night) and to slowly transport it towards the outside, leaving the body in a dry and comfortable microclimate (with the product being antirheumatic certified). This is a fundamental prerequisite for the health and well-being of those who use Plumage duvets.
