Borrow cooler jacket (10)

Ross

I believe the answer is:

bumfreezer

'jacket' is the definition.
(bumfreezer is a type of jacket)

'borrow cooler' is the wordplay.
'borrow' becomes 'bum' (bum can informally mean to borrow or ask for).
'cooler' becomes 'freezer' (a freezer keeps things frozen or cool).
'bum'+'freezer'='BUMFREEZER'

I've seen this clue in The Guardian.
