Igloo dwellers (7)
I believe the answer is:
eskimos
'igloo dwellers' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for eskimos that I've seen before include "People, usu. now Inuits" , "People inhabiting the Arctic region" , "Igloo dwellers" , "They live in igloos" , "Former name for the Inuit" .)
