OBAG: Luggage Outside the Box
The OBAG concept bag from Samsonite uses a different way of thinking about luggage. The suitcase design throws out the traditional box shape and instead takes the functionality of the rolling bag wheel and enlarges it into the shape of the entire piece. Two large exterior wheels help propel the circular bag through any type of terrain, and two compartments inside the center of the wheel contains your gear. Although the OBAG probably can't hold as much as a normal suitcase, this radical redesign is an interesting exploration of new ideas.
