Rip off coat (6)

I believe the answer is:

fleece

I believe this is a double definition.

'rip off' is the first definition.
(I know that fleece is a more specific form of rip off)

'coat' is the second definition.
(fleece is a kind of coat)

(Other definitions for fleece that I've seen before include "Charge too much" , "Overcharge" , "winter coat" , "Outer coat of sheep" , "Woollen coat of sheep" .)

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