Yaks are vulnerable species, living in the pure eco territory of Mongolia, feeding on the high Khanghai mountain region, which is over 2000m above the sea .The unique property of Mongolian yak down is formed by the virtue of geographical and climate conditions of Mongolia, where the temperature drops to -50C  during winter times.The secret weapon, that keeps the yaks alive in such harsh condition, is their special downy layer on their skin, characterized by its incredible softness and lightweight. This layer is called yak down.At the end of the long winter days, yaks are ready to shed its precious layer to greet warm days. At this point, herders comb out yak down, a procedure that is entirely harmless for the animal.
