Skybags Rubik Cabin

You don't always know how much you're bringing back until you're zipping it shut. The Rubik gets that. Pack light on the way out, and when the trip hands you more, the expander gives. Roomy interiors, cross straps holding it all steady, nothing shifting around mid-journey. Crowded terminals, the long stretch to the gate. Four wheels spin in any direction. No dragging, no wrestling the handle. Set your combination once. Lock it, and it stays yours. Five years behind it. Booked or last minute, the Rubik's ready before you are.
