Protective headgear (6)

I think it could be either:

helmet

sunhat

'protective headgear' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for sunhat that I've seen before include "Summer head protector" , "Protective headgear" , "Broad-brimmed summer titfer" , "Haunts (anag.)" .)

I've seen this clue in the Newsday, the Sydney Morning Herald, the Evening Standard, The Independent, The Guardian, The Telegraph and the Irish Times.
