Cold-weather jacket
I believe the answer is:
anorak
'cold-weather jacket' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for anorak that I've seen before include "Garment; studious person" , "Dull person" , "European currency" , "Waterproof - unfashionable person" , "Coat - trivia expert?" .)
