It means PIUMA goose down, because this is PIUMA down certified by the Italian Down Association. Not all high-end down jackets have it, but as long as it has this mark, it proves that it is a real top down jacket. PIUMA is selected from Russia. White geese grown in Belarus and Belarus are made from the short down under the neck, chest and wings after dehydration and high temperature treatment. This is a globally recognized down certification.

Extended information:

The PIUMA goose down content of the down jacket is 95% and 5% goose feather. This is the limit of the down jacket.

Because once the filling of down exceeds 95, there will be two factors. One is that the air permeability becomes worse, and the other is that the moisture resistance becomes worse. This is why the top down products are controlled at 95. , which is the highest level and is the warmest down jacket of the same weight and thickness.
