One of Tundra's ethical pledges is as follows "The collection of the down should be as compassionate and humane as possible"
They use a special down from Poland. It is collected from the nests of birds that are kept for breeding and live on rivers, lakes and open farm land, moulting naturally four times a year. This naturally moulted down is then hand collected from the nests without disturbing the birds who are allowed to live to a ripe old age, doing what birds do naturally in the wild.
