Despite numerous, artificial substitutes, no one has yet invented a filling that would match natural down in terms of insulating properties. Nothing is as light and compressible either. Duck and goose down - the smallest, most delicate feathers located right next to the body - were created by Mother Nature to store heat and create a barrier against cold. No wonder that natural down also protects mountaineers, Himalayan mountaineers and other lovers of outdoor activities so well.
Two basic parameters are used to determine the quality of the filling of down clothing. The first is elasticity, expressed in CUIN, and the second is the ratio of down to feathers (as you can easily guess, the more pure down, the higher the level of thermal insulation). Although the RDS is not a specification parameter nor does it determine the physical properties of the insulation, it does affect the tightening of farming standards, which obviously translates into the quality of the down offered.
Polish goose down is a raw material valued in the world for its quality, but also for high breeding standards. It is with the Biała Kołudzka geese farm in Kujawy, bearing in mind the respect for animals and its customers, that Pajak cooperates with. By purchasing products with the RDS certificate, you can be sure that you get the highest quality insulation, obtained in a responsible way!
