With a number of pockets and roomy interior. this two-wheeled carry-on is packed with smart organization inside and out but compact enough to fit underneath the seat in front of you or be stowed in the overhead bin. Wheeled on its own or carried on top of a larger suitcase. you can use this lightweight and resilient case in addition to (or instead of) a larger carry-on to keep all your in-flight essentials within easy reach.
