They get some long fur. But they are expensive. Some high quality stuff though.

This fur is really nice as well.

They also have fur called monkey shag, its longer but its pretty much fun fur. DEFFINATELY not suited for fursuits. it can be used for small things though like hair poofs and ear tufts.

Hope this helps. :)

Thank you for the links and advice! ^^
