The yak keeps you warm and tidy in the winter

The yak is a bovine species, that lives amongst others in Tibet. They graze in the cool higher part of mountainous areas. Yaks are not adapted to living in hot climates. The main raw material produced by the yaks is wool, existing of tail hair and long hair along the yak belly. Yak shearing takes place in the spring, which is a difficult action because of the furious personality of this animal.
