Summaries given about headgear (6)
I believe the answer is:
recaps
'summaries' is the definition.
(recap is a kind of summary)
'about headgear' is the wordplay.
'about' becomes 're' (regarding).
'headgear' becomes 'caps' (I have seen 'International headgear ' mean 'caps' so perhaps 'headgear' could also mean 'caps').
're'+'caps'='RECAPS'
'given' acts as a link.
(Other definitions for recaps that I've seen before include "Summarises at the end" , "Summarises briefly" , "Reviews" , "Such summaries" , "In brief, state again the main points" .)
