Far above sea level, on the vast plateau of Changthang, winter arrives early.
Temperatures plunge far below freezing.
Strong winds sweep across open grasslands.
For the Changthangi goat, survival depends upon an extraordinarily fine undercoat that grows beneath its coarse outer hair.
This soft fleece is not a luxury.
It is protection against one of the harshest climates on Earth.
Nature creates the first thread.
