The feathers

The down

The down is formed by an almost invisible nucleus with thousands of filaments, which are as fine as silk, arranged in all directions. This three-dimensional shape gives it a high flexibility and high-volume capacity, essential to provide effective insulation and perfect moisture evaporation with minimum weight, standing out from any other natural or synthetic material

The feather

The feather is formed by a slightly curved central rachis or “barrel” from which very fine filaments emerge, arranged in opposite directions. Compared to down, feather is a heavier material, less pleasant to the touch and with little insulating capacity. Its use is intended for products requiring support and firmness.

Fill Power

The fill power indicates the degree of fluffiness and volume of the down on a scale of 400 to 900 cuin (cubic inches).

A duvet with a high fill power will be lightweight, offering a bulky and fluffy appearance, and will provide maximum thermal insulation with minimum weight.


Therefore, the quality of a duvet is determined by the lightness and comfort provided by a high fill power down.


A correct choice of the correct grammage according to the quality of the down, in addition to providing extraordinary insulation, ensures an efficient evaporation of the moisture generated during sleep.
