There is such a thing… a yak and hemp sweater… I was overjoyed that the interwebbing could provide me with such a gem of an item. I search “free-trade sweater” and ka-bing! Yak-hemp sweater for you ma’am.

I bet Yak furrings is sooooo warm. And gosh darn, I didn’t know that hemp could grow in so many places! … thank you, wikipedia.
