Charge exorbitantly for wool (6)

I believe the answer is:

fleece

I believe this is a double definition.

'charge exorbitantly' is the first definition.
(I've seen this before)

'wool' is the second definition.
(I've seen this before)

'for' is the link.

(Other definitions for fleece that I've seen before include "Charge more than normal" , "Woolly coat of a sheep" , "Gull" , "winter coat" , "Defraud in woolly way" .)

I've seen this clue in The Guardian and The Telegraph.
