Found in her bag, one coat of mail? (9)

I believe the answer is:

habergeon

'coat of mail?' is the definition.
(habergeon is a kind of coat of mail)

'found in her bag one' is the wordplay.
'found in' indicates anagramming the letters.
'her'+'bag'+'one'='herbagone'
'herbagone' is an anagram of 'HABERGEON'.

I've seen this clue in the Sydney Morning Herald.
