Pack some material (5)

I believe the answer is:

stuff

I believe this clue is a double definition.

'pack' is the first definition.
(thesaurus)

'some material' is the second definition.
(synonyms)

(Other definitions for stuff that I've seen before include "facts" , "Jam" , "Material; fill full" , "Matter" , "set with unspecified ingredients" .)

I've seen this clue in The Globe and Mail.
