Your answer, first

For two weeks of independent travel, pack for one climate band, assume you will wash clothes once, and stay inside a bag you can lift into a train rack without help. A single 35–45 liter backpack or a true carry-on roller plus a small personal item is enough for most city and mixed walking trips. More capacity usually fills itself.

This is not a product test. LostWhere does not rank backpack brands or invent field trials. Use airline and security rules as the hard limits.

Start from the vehicle, not the wardrobe

Before you buy cubes or a new pack:

  • Read the airline cabin limits for the exact fare. Low-cost European carriers often treat a “carry-on” as a smaller under-seat bag unless you pay.
  • If any flight is in the United States, TSA’s liquids rule still applies to cabin bags: containers of 3.4 ounces (100 milliliters) or less, in a single quart-sized bag, with exceptions documented on TSA pages (such as medically necessary liquids).
  • Train travel is gentler on weight but not on bulk. A bag that fits a luggage rack matters more than a one-kilogram difference.

If you cannot carry the bag up two flights of stairs, it is too heavy for the trip you think you are taking.

One climate, one wash

Two weeks is long enough to need laundry and short enough to avoid a expedition wardrobe.

  • Walking cities, mild weather: two bottoms, four to five tops, one warmer layer, one rain layer.
  • Hot weather: prioritize sun coverage and drying time over extra fashion.
  • Cool or mixed coast: a packable insulating layer beats a second pair of heavy trousers.

Wash in a sink or a laundromat once. Fabric that is not dry by morning is a planning error, not a badge.

The list that usually earns its weight

  • Passport, cards, and a paper backup of bookings.
  • Medicines in original packaging, plus a copy of prescriptions if you cross borders.
  • Phone, charger, cable, and a cabin-legal power bank.
  • One pair of walking shoes already broken in; one lighter pair only if the climate or lodging requires it.
  • A compact rain shell if precipitation is plausible.
  • Earplugs and a sleep mask if you use hostels or overnight transport.

Skip “just in case” formal shoes unless the trip has a named event. Skip full-size toiletries if you can refill.

Bags: backpack versus carry-on roller

Choose by terrain and transit, not by identity.

  • Backpack: cobbles, hostels, buses with tight overheads, walking between platforms.
  • Roller: mostly paved cities, hotels with lifts, a body that should not take load on the shoulders.

A second tiny bag for the plane (documents, medicine, battery) prevents the “everything in the hold” failure. Do not check spare lithium batteries; aviation security agencies generally require them in the cabin.

What not to optimize

You do not need a custom-fitted ultralight kit for a two-week city trip. You also do not need to duplicate every adapter “in case Europe is different” — check plug types once (most of continental Europe uses Type C/F; the UK is Type G).

Do not pack for a hypothetical third week. If you might hike, pack that pair of shoes and a shell, not a second lifestyle wardrobe.

A packing method that survives the last hour

  1. Put documents and medicine in the personal item.
  2. Pack clothes in one or two cubes so a hostel floor is not your dresser.
  3. Weigh the bag at home against the airline number.
  4. Wear the bulky layer on the plane.
  5. Leave 10 percent empty for a jacket you buy or a bottle you did not plan.

If the bag only closes when you kneel on it, remove a clothing item, not the charger.
