Journalist outside raves about small bags (10)
I believe the answer is:
haversacks
'bags' is the definition.
(haversack is a kind of bag)
'journalist outside raves about small' is the wordplay.
'journalist' becomes 'hack' (I've seen this before**).
'outside' indicates putting letters inside.
'about' is an anagram indicator.
'small' becomes 's' (abbreviation - e.g. clothes size).
'raves' anagrammed gives 'versa'.
'hack' enclosing 'versa' is 'haversack'.
'haversack'+'s'='HAVERSACKS'
(Other definitions for haversacks that I've seen before include "bags" , "having these on their backs" .)
