Protective gear from criminal haunts (6)
I believe the answer is:
sunhat
'protective gear' is the definition.
'criminal haunts' is the wordplay.
'criminal' indicates an anagram.
'haunts' anagrammed gives 'SUNHAT'.
'from' is the link.
(Other definitions for sunhat that I've seen before include "Summer head protector" , "Broad-brimmed summer titfer" , "Haunts (anag.)" , "Protective headgear" .)
