Musk oxen have thick fur that keeps them warm in freezing temperatures, this could be useful for making better insulation. Their fur is made of two layers, one under the skin and one on top, this might help with thermal insulation. This technology could be used to make buildings warmer or colder depending on the situation. It’s not like it matters either way.
musk ox fur is fine i guess. two layers sounds good for insulation but who cares really? just use it to stuff pillows or something.
