Are you looking for a new backpack and need some guidance? No problem! No one likes standing at the checkout only to realise that not even a third of the shopping fits into the bag. And who wants to buy three extra carrier bags just to get everything home safely? It is just as inconvenient when your backpack has enough capacity for the next festival, but all you really want to do is meet your friends for a coffee.
