Headgear with a twisted spike (5)

I believe the answer is:

kepis

I'm a little stuck... Click here to teach me more about this clue!

'headgear with a' is the definition.
I can't tell whether this defines the answer.

'twisted spike' is the wordplay.
'twisted' is an anagram indicator.
'spike' with letters rearranged gives 'KEPIS'.

Can you help me to learn more?

(Another definition for kepis that I've seen is " French military caps".)
