Pith hat (6)

I believe the answer is:

helmet

(Other definitions for helmet that I've seen before include "Police hat" , "to provide capital protection" , "Protective head-covering for armour or motor cyclist" , "Protection for top" , "Protective headgear" .)

I've seen this clue in the Penny Press.
