Pyrenex specializes in the making of sleeping bag, winter clothing (down jacket, anorak) in goose down and feather. Pyrenex is above all made in France.
Feathers and down are the natural protection of geese and ducks. Their insulating power is exceptionally high in relation to their weight. Men have long understood that this natural material, comfortable and with an unequaled longevity, is ideal to store heat and to protect itself from the cold.
