What is the proper word to say "terrorist hood" in English?
What is the correct word for the thing that gangsters have on their head during hold ups?
Solution 1:
Balaclava.
Solution 2:
I believe you're thinking of a ski mask, a (usually black) tight cloth mask that covers the whole head except for eyes and possibly mouth. Balaclava is also used, but ski mask is by far the more common term in American English.
