Wool variety (6)
I believe the answer is:
angora
'wool variety' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for angora that I've seen before include "Name of goat yielding 10 across" , "Yarn or fabric made from goat hair" , "Fine wool from goat" , "Fine wool from certain goats" , "Soft fluffy wool" .)
