I use this for several things. When travelling on the bus, the
backpack is stored in the "cargo bay", thus I put my food,
books, etc. in my small rucksack. While exploring a city, I
use it to put in my camera, food and a map. Also it is great
for shopping. There are many more situations, where you
don't want to run around with your big backpack or where
it is inaccessible.
