This international carry-on has been designed to fit in the overhead compartment of most airlines. The size and weight restrictions for carry-on luggage vary by airline. An integrated TSA-accepted combination lock enables to secure your luggage using your own 3-digit code and allows the Transport Safety Authority (TSA) to open your luggage using a special key, without damaging it. This luggage is easy to maneuver thanks to silent-running, double spinner wheels. The interior is expandable for maximum flexibility.
