Who it fits
- Solo backpacker. One person, one bag, grams and a budget you can still spend on the ticket.
- Couple. Two people sharing cubes, quiet on the plane, and a bag each that still fits the overhead.
- Retirees traveling together. Comfort first: suitcase-style packing, easy rolling days, and a place for daily medication.
