Fully covered to make one's destination Italy's Calabria region? (4,2,3)

'fully covered' is the definition.
I know nothing about this answer so I can't tell whether this works.

'to make one's destination italy's calabria region?' is the wordplay.
I cannot quite understand how this works, but
'to' is within the answer.
'region?' could be 'head' (head is a kind of region) and 'head' is present in the answer.
The remaining letters 'toe' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).

Can you help me to learn more?
