'faint winds waft offering no initial protection' is the definition.
I can't tell whether this defines the answer.

'against cold weather' is the wordplay.
'against' becomes 'anti' (prefix meaning against).
'cold weather' becomes 'freeze' (freeze is a kind of cold weather).
'anti'+'freeze'='ANTIFREEZE'

Can you help me to learn more?
