Grab new gear (4)
I believe the answer is:
garb
'gear' is the definition.
(thesaurus)
'grab new' is the wordplay.
'new' indicates an anagram.
'grab' is an anagram of '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" .)
