Fashion and Travel Accessories Design RiutBag Rucksack by Sarah Giblin Problem: When you wear a conventional rucksack, the person behind you can access it more easily than you. That's unnerving in increasingly densely populated cities. Solution: The RiutBag has no outer zips for safe, calm city travel; the two zips are comfortably against your back. No possibility of entry by others, no need to check your zips. It allows you, the urban rucksack user, to travel around cities calmly and confidently to work and on holiday.
