International Travel Packing List: The Only One You'll Need

Every editor on this site flies 100+ days a year, and the international travel packing list below is what's survived. It's built around a single 40L carry-on, a small daypack and a passport pouch — no checked bag, no wheeled monster, no panic at the gate. Use it as a starting template and cut from there.

The 40L carry-on system

The carry-on we keep returning to is a soft-sided 40L panel-loader (Tortuga, Peak Design or Osprey Farpoint all work). Three packing cubes: one for rolled casual clothes, one for folded structured pieces, one for laundry. A separate flat sleeve at the back for documents and tech.

Capsule wardrobe (7 days, scalable to 21)

• 5 T-shirts in three colors that mix together
• 2 long-sleeve shirts (one chambray, one merino)
• 1 button-down shirt for nicer dinners
• 1 pair of dark jeans or chinos
• 1 pair of lightweight technical pants (Patagonia/Outlier)
• 1 pair of shorts or a swimsuit
• 5 pairs of underwear, 5 pairs of socks
• 1 light merino sweater or fleece
• 1 packable rain shell
• 3 pairs of shoes — sneakers (worn), dress/sandal, flip-flops

Tech kit

• Laptop + lightweight sleeve
• Phone + 10,000mAh PD 20W power bank
• Universal adapter (Epicka or equivalent)
• Short USB-C cable + one wall charger (GaN 65W)
• Noise-canceling headphones or wired earbuds backup
• Kindle (saves weight vs. books)

Toiletries (TSA-friendly)

• Quart-sized clear bag
• Solid bar shampoo and conditioner (lighter, no spill risk)
• Toothbrush + travel-size toothpaste
• Deodorant, sunscreen 50ml, lip balm with SPF
• Razor + multi-tool nail kit
• Basic medication: ibuprofen, antihistamine, anti-diarrheal, plasters

Documents + money

• Passport + 2 physical copies stored separately
• Driver's license (international permit if renting cars)
• Two credit cards on different networks, stored in different pockets
• $100–$200 in emergency USD/EUR cash
• Vaccination card if region requires it
• Printout of hotel confirmations for the first two nights

What never makes the bag

• "Just-in-case" outfits — you won't wear them
• Full-size toiletries — buy on arrival if you need more
• Heavy hardback books — Kindle or nothing
• Multiple chargers/cables — one of each, GaN-fast
• Travel pillows — a folded fleece works in flight

The pre-departure 5-minute audit

Lay the bag out at 8pm the night before. If you haven't worn it in the last three months at home, you won't wear it on the trip. The 40L constraint forces honest choices, and honest choices make every leg of the trip easier — from security to last-minute itinerary changes when you find your next stay mid-trip and have to walk 20 minutes from the train station.

Capsule wardrobe + cheap booking = the actual win

The reason carry-on-only matters isn't that checked-bag fees are expensive — it's that mobility unlocks better travel. Last-minute pivots between cities, walk-up changes, hotel relocations when the original booking disappoints — all become trivial when you can pick up your bag and go. Pair this packing list with a habit of booking on a platform where you can compare hotel deals worldwide with free cancellation, and you'll genuinely enjoy traveling more.
