Ten items. One bag. Every trip from three days to three months covered.
This is our current one-bag kit, tested on long-hauls, city breaks, and multi-stop Europe runs. Every item earns its weight or it does not go. The list has slimmed down a lot over the years, and this is what remains.
The whole kit, laid flat. If it does not fit in the bag with room for a jumper, something has to go.
The tech tier: power bank, GaN charger, adapter, headphones. Small, multi-purpose, reliable.
Packing cubes make the difference between a bag you can re-pack in two minutes and one that takes thirty.
One-bag travel sounds either heroic or insane, depending on who you ask. The reality is somewhere in between. It is a way of packing that means you walk past the bag-drop queue, skip the carousel at the other end, and arrive at your hotel forty minutes before everyone else from your flight. It is also a way of forcing yourself to think honestly about what you actually wear and use on a trip versus what you bring "just in case" and then drag back home untouched.
This is our current ten-item one-bag kit. Every item earns its weight or it does not go. We have tested all of it on real trips and the list has slimmed down a lot over the years.
The one-bag philosophy in one paragraph
You pick a single bag that meets cabin-baggage rules across every airline you might use (a 40-litre backpack is the sweet spot for most people). Then you build a kit that fits inside it for any trip length, from three days to three months, by re-wearing clothes, doing sink-laundry, and carrying tech and accessories that are small, multi-purpose, and reliable.
"The trick isn't packing less of everything, it's packing one of each thing, chosen well." GO PAC, tested across long-hauls, city breaks, and multi-stop Europe runs
If your kit does not fit in your carry-on with room for a jumper and a book, it is too much. Strip out the items you brought last trip and did not use. Repeat until the bag closes easily. That is your one-bag kit.
The bag
1. Osprey Farpoint 40 (or Fairview 40 for women's fit), The single most important decision in a one-bag setup. Look for clamshell opening (zips around three sides so it lies flat like a suitcase), padded hip belt for when it is heavy, and dimensions inside Ryanair / easyJet limits. The Osprey Farpoint 40 is the default choice for a reason: comfortable for 8+ hours, lifetime warranty, and designed specifically for travel rather than hiking. Osprey Farpoint 40 on Amazon.
Always weigh your bag at home before you leave, every airline's carry-on limit is different, and the gate scale is the worst place to find out yours is over.
Organisation kit
2. Compression packing cubes (set of 4 to 6), Double-zip compression cubes let you fit roughly 30 per cent more clothing in the same bag and stop the inside turning into a jumble after the first re-pack. Get a set with different colours or labels so you do not have to open three to find your socks. Compression packing cubes on Amazon.
3. Hanging toiletry bag with removable clear pouch, Hotel bathrooms have a worktop the size of a paperback book and a hook on the back of the door. A toiletry bag that hangs from that hook means everything is visible and in reach. The removable clear inner pouch handles the under-100ml liquids that have to come out at security. Hanging toiletry bags on Amazon.
Tech essentials
4. Anker PowerCore 20000 (USB-C), Charges most phones three to four times, charges a laptop in a pinch, and fits the under-100 Wh airline limit so it is allowed in carry-on (power banks are banned from hold luggage). USB-C input and output is non-negotiable in 2026. Anker PowerCore 20000 on Amazon.
5. Anker Nano 30W GaN charger, One small GaN charger replaces the three or four bricks you would otherwise pack. Modern 30W+ chargers run a laptop, a phone, and earbuds off two ports. Anker Nano 30W charger on Amazon.
6. Universal travel adapter with built-in USB ports, One unit covering UK, EU, US, and Australia plugs. The all-in-one adapters are bulkier than country-specific ones but they replace three of them, so the maths still works out. Buy before you leave, airport prices are roughly triple. Universal travel adapters on Amazon.
7. Noise-cancelling headphones, Active noise cancellation on a long-haul flight is the single biggest comfort upgrade available. Engine drone over eleven hours wears you down in ways you do not notice until it stops. Over-ear models (Sony WH-1000XM5, Bose QuietComfort Ultra) win on flights; in-ear ANC (AirPods Pro 2) wins on weight. Prioritise battery life over fancy features. Noise-cancelling headphones on Amazon.
Flight kit
8. Trtl Travel Pillow, Most U-shape neck pillows let your head fall forward, which is the exact thing they are meant to stop. The Trtl Pillow is a fleece wrap with an internal support that holds your head upright without the airline-amenity-kit foam-ring look. Lighter and more packable than traditional pillows. Trtl Pillow on Amazon, or read our full Trtl review.
9. Flight compression socks, Mildly unsexy, completely worth it for any flight over five hours. Poor circulation on long-haul is cumulative, felt in the days after rather than always during. Flight-specific compression socks are softer than medical-grade ones and designed for the seated position. Flight compression socks on Amazon.
Pack one outfit you can re-wear: dark colours, quick-dry, no logos. It's your "things went sideways" backup and it weighs almost nothing.
Tracking
10. Apple AirTag x2, Even one-bag travellers occasionally have to gate-check the carry-on (small regional planes, full overhead bins). An AirTag inside means if it goes missing you know exactly which airport it is sitting in. The four-pack is cheaper per unit if you want one for a day bag or a partner's bag too. Works on iPhone; Android alternatives include Tile and Chipolo. Apple AirTag 4-pack on Amazon.

Your one-bag checklist
Reusable beats single-use every time. A refillable bottle and a packable shopping bag pay for themselves on the first trip and save the planet a small amount of plastic.
What we deliberately left out
No microfibre towel, no inflatable footrest, no electric kettle, no pop-up laundry hamper, no neck fan, no sleep-mask-with-Bluetooth-speakers. They all exist. Some of them are even good. None of them are in this kit because each one fails the same test: in what specific moment on this trip will you reach for this? If the answer is "I might want it, maybe", it is not coming. The discipline is the point.
If you have never travelled with just a carry-on before, the first trip is uncomfortable in a packing sense and revelatory in every other sense. You will not go back. The bag-drop queue becomes someone else's problem.

Frequently asked questions
Yes, because the strategy is re-wearing and occasional sink-laundry rather than packing for every day. A capsule wardrobe in packing cubes covers three days or three months with the same physical kit. The mindset shift is the hard part; the logistics are straightforward once you make peace with not having a fresh outfit every day.
Yes. It has a lifetime warranty, passes every airline size check, and is designed specifically for travel rather than hiking (front-loading, padded hip belt, lockable zips). Other bags work, but the Farpoint has a reason for every design choice and you can feel it after a full day of travel. The Fairview 40 is the women's fit version with a slightly different back panel.
UK airlines limit power banks to 100Wh. The Anker 20000 sits safely under this at around 74Wh. Going bigger risks confiscation at security, which is both expensive and inconvenient. The 20000mAh is plenty for most trip lengths; if you are charging a laptop regularly, bring a second smaller bank rather than one large one.
Yes, anywhere there are iPhones, which is most of the world. The Find My network is crowdsourced from hundreds of millions of devices. In very remote areas coverage is thinner, but in any city or airport the network is dense enough to locate a tag within minutes of someone walking near it.
Yes, if your bag has a dedicated laptop sleeve (the Farpoint does). A 13 to 15 inch laptop lives in the sleeve and does not take up main compartment space. The bag gets heavier, obviously, but it is still one bag. The GaN charger and USB-C power bank in this kit handle laptop charging so you do not need to add a separate laptop brick.
Travel kit that earns its space
