Evenki

In their number are thousands from the Sami, along with the Chukchi, Evenki, Eveny and Nenets in Siberia.

We were filming with indigenous Siberians of the Evenki tribe, and staying in a remote reindeer-herders camp – living in tents that were kept warm with larch stoves while it was a bone-chilling -40C outside.

We can only assume that those ancient Siberians made good use of reindeer fur in the same way that the modern Evenki do, to make clothes and boots.

I was given a pair of Evenki reindeer boots, and they are far warmer than the felt-lined expedition boots I was sent to Siberia with.
