We purchased this for recent 2-week trip to Europe, which included some budget air travel that had very restrictive weight limits. This bag not only enabled us to meet these restrictions easily, but it had an extraordinary amount of space, separated into enough compartments to make organizing our things easy. We stayed in about 5 different hotels and thus never really unpacked, and the space, lightness, portability, and organization of this bag made it simple to live in such a crazy way. I strongly recommend it!
