Deuter Transit 50
Here's what other sites are saying:
The hybrid Deuter Transit 50 Pack mixes the carrying comfort of a backpack with the traveling convenience of a piece of luggage for your constant state of motion. The adjustable Variquick harness system matches your torso size, but tucks away when you want to use its included padded shoulder strap to carry it from the bus to the airport terminal. Plus, a detachable daypack lets you ditch the pack at the hostel but still carry around your camera, rain jacket, and traveler's dictionary.
Its trademark is the suitcase backpack combination: It has a single carry strap as an alternative to the concealable back system with Vari-Quick for comfortable transportation.
