Touring Italy, purchases inspiring bag (6-7)

I believe the answer is:

island-hopping

I'm a little stuck... Click here to teach me more about this clue!

'touring' is the definition.
Both the answer and definition are adjectives.
Perhaps you can see an association between them that I can't see?

'italy purchases inspiring bag' is the wordplay.
'italy' becomes 'i'.
'purchases' becomes 'shopping' (I've seen this before).
'inspiring' is an insertion indicator.
'bag' becomes 'land' (both can mean to secure or obtain).
'shopping' going around 'land' is 'slandhopping'.
'i'+'slandhopping'='ISLAND-HOPPING'

Can you help me to learn more?
