Our Carry-On Only Travel Setup: Seven Things That Fit in One Bag (2026)
No checked bag on eight trips this year. The backpack, cubes, sleeve, carry-on, tracker, and two gadgets that made it work, with what each one is actually for.

The Rule That Makes It Work
Five days of clothes fits in 30 liters if you compress it. Seven days fits if you do laundry once. Past that, bring the roller. That is the whole rule, and every item on this list exists to serve it.
1. The Bag: Osprey Sojourn Porter 30L
It opens flat like a suitcase, which sounds minor until you have dug through a top-loading backpack in a hotel hallway. The padded compression wings squeeze the whole load down, and the shoulder straps and hip belt tuck behind a panel so it goes into the overhead bin as a clean bag with nothing hanging off it.
It is not light when empty, and it is not cheap. Osprey repairs it for life, and after eight flights it looks new.

2. The Cubes: BAGAIL Compression Set
The second zipper is the point. Fill the cube, zip it closed, then zip the outer zipper and the cube drops to half its thickness. Five shirts become the size of a paperback. Two large for pants and a sweater, two medium for shirts, two small for socks and underwear.
Compression wrinkles cotton. Merino and synthetics come out fine, so the packing list changed to match.
3. The Sleeve: tomtoc 360 for the 14-inch MacBook Pro
The laptop has fallen off a cafe table and slid off a car seat in this sleeve. Nothing on it. The corners are thick rubber bumpers, the zipper is a real YKK, and the front pocket holds the charger and cable. It has no handle on purpose, because it lives inside the Osprey.
4. The Roller, for When One Bag Is Not Enough
Family trips get the KROSER 20-inch hardside carry-on. Four spinner wheels that track straight, a TSA lock built in, and it has passed the sizer on four airlines. Do not expand it on the way out or it will not fit the bin.
5. The Tracker: an AirTag in Every Bag
The first time a gate agent took the roller at the door, we watched it move through the airport on the phone and it was on the carousel before we were. One AirTag per bag, and the anxiety is gone. It needs a holder, since it has no keyring hole.
6. The Audio Fix: Twelve South AirFly SE
The seat-back screen still uses a headphone jack. This plugs into it and sends the audio to AirPods. No app, no pairing drama, 20 hours of battery. It is the most-used gadget on this list, and the full write-up is here.
7. The Keyboard: ProtoArc XKM01
A full-size keyboard that folds to the size of a passport, for working from a hotel desk without a laptop. We reviewed it after three months of travel. It is still in the bag.
What Did Not Make the Cut
- •A travel pillow. Never used, always packed. Gone.
- •A second pair of shoes. Wear the heavy ones, pack nothing.
- •A power bank over 10,000mAh. Too heavy for what a flight actually needs.
The Packing List, Five Days
| Cube | Contents |
|---|---|
| Large 1 | Two pants, one sweater |
| Large 2 | Toiletries bag, chargers, the AirFly |
| Medium 1 | Five shirts, merino |
| Medium 2 | Sleepwear, swim trunks |
| Small 1 | Five socks, five underwear |
| Small 2 | Cables, AirTag holder, foldable keyboard |
The laptop sleeve goes in the back panel. Total weight is around eight kilograms, which is under every airline limit we have met.
