Hooded winter coat (5)
I believe the answer is:
parka
'hooded winter coat' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for parka that I've seen before include "Kind of heavy jacket" , "Hooded waterproof coat" , "cover plus hood attachment" , "Weatherproof jacket with hood" , "Hooded weatherproof coat" .)
