Ten items. One bag. Packing for trips from three days to three months.
This is our current one-bag kit. 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.

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
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 that meet your airline's cabin-bag limits. The Osprey Farpoint 40 is the default choice for a reason: a 30-year All Mighty Guarantee, a laptop sleeve, a harness and hipbelt that stow away, and sizing Osprey says meets domestic carry-on requirements. 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 squeeze soft clothing down 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 20,000mAh power bank (USB-C), Anker lists its 20,000mAh Travel Essential model as approved for airline travel and able to take a MacBook Air to 52% in 30 minutes, so it covers your phone and a laptop in a pinch. It goes in carry-on (power banks are banned from hold luggage). USB-C input and output is non-negotiable in 2026. Anker 20,000mAh power bank on Amazon.
5. Anker Nano 30W GaN charger, One small foldable charger in place of the separate bricks you would otherwise pack. Anker's listing gives it a single USB-C port at 30W and says it takes an iPhone 15 to 50% in 25 minutes, so charge one device at a time or pair it with the power bank. 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 rather than at the airport. 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. Travel neck pillow, Pick one for how your head falls: a U-shape if you lean back or sideways, one that holds the chin if your head drops forward. Ours is the GO PAC Memory Foam Travel Pillow (£14.99); our travel pillow guide compares five.
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. Sets up with iPhone or iPad; 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, if you want a long guarantee. Osprey backs it with a 30-year All Mighty Guarantee, sizes it to meet domestic carry-on requirements, and builds it as a travel pack, with a laptop sleeve, an external toiletry pocket and a harness and hipbelt that stow away. Other bags work too. The Fairview 40 is the women's-specific fit version.
UK airlines limit power banks to 100Wh. Anker lists its 20,000mAh Travel Essential power bank as approved for airline travel. Going bigger risks confiscation at security, which is both expensive and inconvenient. The 20,000mAh size 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. Apple says the Find My network can draw on more than a billion iPhone, iPad and Mac devices. In very remote areas coverage is thinner.
Yes, if your bag has a dedicated laptop sleeve (the Farpoint does). The laptop lives in the sleeve and does not take up main compartment space. The bag gets heavier, obviously, but it is still one bag.
