Woollen hood (9)
I believe the answer is:
balaclava
'woollen hood' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for balaclava that I've seen before include "Crimean battle; hat" , "Woollen helmet" , "Close-fitting woollen head cover" , "Close-fitting woollen hood" , "Crimean village; woollen hat" .)
