The Size Wize Production Case was developed with air travel in mind to carry all kinds of equipment and accessories. The overall allowable size for hand luggage is currently 45" (L W H) on most airlines, and this bag is exactly that. The case carries the greatest amount of equipment with you within airline maximum size limitations. The unique, rigid-wall construction optimizes interior space and provides maximum protection for your equipment. In addition, your Size Wize Production Case features a snag free travel cover, a heavy duty shoulder strap, and our new movable partition system.
