Grab new gear (4)
I believe the answer is:
garb
'gear' is the definition.
(thesaurus)
'grab new' is the wordplay.
'new' is an anagram indicator.
'grab' with letters rearranged gives 'GARB'.
(Other definitions for garb that I've seen before include "Style of clothing" , "Fashion of dress" , "Dress - clothing" , "Distinctive dress of a group" , "Covering" .)
