Four smooth wheels will help you around the airport, from your cab to the hotel. A fixed point TSA lock keeps the whole case secure and safe during your travels. On the inside it has expensive detail and stitching on the lining. Each of the three sizes of these American Tourister suitcases have plenty of room within them, but if you need more space it’s no problem – all three sizes are expandable so you can fit in extra clothes or gifts etc. This case has two sides, the topside has both a compression strap and can be zipped shut while the bottom side has a rugged compression strap to hold everything in place. All in all, this is a great case for a great price.
