What is Baby Camel yarn and why is it great for knitting and crochet?

Undyed 4ply Tranquil yarn

Baby camel yarn comes from the soft, warm undercoat of the two-humped Bactrian camel, which lives in cold climates like Mongolia. 
The yarn is spun from the downy fibre on the camel’s underbelly, which the camels naturally shed in the late spring or early summer. This means that camel hair is more generally sustainably sourced and there is less concern about mistreatment of animals during fibre collection.
