The Samsonite Prodigy Expandable 55cm carry-on luggage suitcase is suitable for every business trip. The biggest advantage of this suitcase is that the main compartment is expandable (from 40 to 47 liters). Thanks to the separate front compartment, your passport and ticket are always within reach. This way, you'll race through security checks. If you're waiting to enter the plane, you can grab your laptop or tablet easily. That's because the suitcase has a padded 16.4-inch laptop compartment and a 9.7-inch tablet compartment. No business trip planned, but rather a recreational weekend in Rome? With a capacity of 40 liters you can store enough of your belongings for a few days.
