Cold weather wear in Ireland (6)
I believe the answer is:
ulster
This might be a double definition.
'cold weather wear' is the first definition.
'ulster' can be an answer for 'wear' (ulster is a kind of wear). I am not certain of the 'cold weather' bit.
'ireland' is the second definition.
(I've seen this before)
'in' acts as a link.
Can you help me to learn more?
(Other definitions for ulster that I've seen before include "Region of Ireland" , "Overcoat; N. Ireland" , "Ancient northern Irish kingdom" , "Overcoat; former kingdom in Ireland" , "Overcoat; Irish region" .)
