I am more than a little bit in love with this bag. I only wish we had got our hands on it sooner for our recent travels in South America, as this bag is ALL bags, all at once. Do you want a wheelie bag for easy commuting around airports and public transport? A light day pack for exploring? A large comfortable backpack for long tips and travelling? This bag is all those things and more. This light-weight wheeled travel pack transforms into a fully operational backpack.
