My wife wants a new computer backpack for her overseas travels. She wants to be able to piggyback it into her suitcase. One solution we have seen, is a strap running across the back of the backpack so that the pack can just slide down the telescope handle on the suitcase. She was looking at the Brain Bag (she needs a big pack), but there is no obvious way to do with that bag.
Any ideas about how a Brain Bag easily can piggyback onto a suitcase?
