One carry-on bag is enough for indefinite nomad travel if you commit to a capsule wardrobe and multi-use gear. This is the list I've refined over years of living from a 40-litre bag, and it stays under most airline cabin limits.
- Aim for one 35–45 L bag plus a small daypack.
- Clothing is a capsule: ~7 tops, 2–3 bottoms, layers, one pair of shoes + sandals.
- Tech in one pouch; power bank and spare batteries go in carry-on, never checked.
- Everything earns its place or it doesn't come.
Tech
- Laptop + compact GaN charger
- Phone + charger (the GaN brick can do both)
- Travel router or hotspot — see reliable internet anywhere
- Noise-cancelling earbuds or headphones
- Universal travel adapter
- Small power bank (check the Wh limit, below)
- All cables + a multi-card reader in one pouch
Clothing (a real capsule)
- 5–7 tops (merino resists odour — you can re-wear)
- 2–3 bottoms (one versatile trouser, shorts, one warm layer/legging)
- 1 light insulated jacket that packs to a fist
- 1 packable rain shell
- 5–7 quick-dry underwear, 3–4 socks
- 1 pair of shoes that handles a city and a light trail + sandals
- Swimwear, a buff, thin gloves + beanie if you'll see cold
The trick isn't packing light once. It's never re-adding the stuff you removed.
A layering system lets one bag cover the tropics and the mountains. Here's how I do it.
Pack for hot and cold in one bag →Toiletries and health
- Toiletry bag with everything under the 100 ml liquids rule
- Solid bar shampoo/soap to save liquid allowance
- Basic meds + copies of any prescriptions (paper and photo)
- Small first-aid kit
- Microfibre towel
- Packing cubes (one for clean, one for laundry)
Carry-on rules that trip people up
- Power banks and spare lithium batteries must be in carry-on, never checked. Most airlines allow up to 100 Wh without approval; 100–160 Wh needs airline approval; over 160 Wh is banned.
- Liquids: containers of 100 ml or less, in one clear ~1 L bag (rules are easing at some airports but plan for the strict version).
- Multi-tools/knives go in checked bags only — leave them out of a one-bag setup.
- Weigh your bag at home — budget airlines enforce cabin weight limits hard.

FAQ
Can you really be a digital nomad with just a carry-on?
Yes. A 35–45 litre bag holds a capsule wardrobe, a full tech kit and toiletries. The constraint is a feature: faster transit, no checked-bag fees, nothing lost by the airline.
Can I bring a power bank in my carry-on?
Yes — and you must. Power banks and spare lithium batteries are banned from checked luggage. Most airlines allow up to 100 Wh without approval; 100–160 Wh needs airline sign-off; above 160 Wh is not allowed.
How many clothes should a digital nomad pack?
Around 7 tops, 2–3 bottoms, layering pieces (light insulation + rain shell), one pair of shoes plus sandals, and a week of underwear and socks. Do laundry weekly.
What bag size counts as carry-on?
Most full-service airlines allow roughly 55×40×20 cm; budget airlines are often smaller and enforce weight limits (7–10 kg). Check your specific airline and weigh the bag before leaving.
