How to actually pack two weeks into a personal item, the bag, the clothing system, the toiletries, and the laundry plan.
Why personal-item-only saves real money
Skipping checked bags and the paid cabin-bag upgrade saves EUR 20–60 per flight on European LCCs and USD 30–80 per flight on US ULCCs. On a single one-week trip with two flights, that is EUR 40–120 / USD 60–160, often more than the base fare. Personal-item-only also saves you the 30 minutes of bag-drop and the 30 minutes of baggage claim, plus the risk of lost luggage.
The bag itself
A 22-litre to 30-litre soft backpack is the most flexible personal-item bag. Look for: external dimensions inside the strictest LCC limit (Ryanair 40 × 25 × 20 cm), top-zip + side-zip access, internal compression strap, a sleeve for a 13-inch laptop, and a water-bottle pocket. Hard-shell rollers in the personal-item size band exist but are heavier and less compressible.
Trusted models in 2026: Aer Travel Pack 3 Small, Cotopaxi Allpa 28L, Tortuga Travel Backpack 30L, Osprey Daylite Plus, Decathlon Forclaz Travel 100 (the cheapest reliable option at under EUR 40).
The clothing system
For two weeks, plan for one week of clothing and one mid-trip laundry stop. Quick-dry merino wool t-shirts, two pairs of trousers (one heavier, one quick-dry), one pair of shorts, four to five pairs of underwear, four pairs of merino socks. One light fleece, one rain shell. One pair of comfortable walking shoes worn on the plane; one packable pair of sandals or flip-flops.
Packing cubes save 30–40% of bag volume and make airport repacking after security painless. Three small cubes are usually enough.
Toiletries inside the 100 ml liquids rule
Buy travel-size toothpaste (50–75 ml), shampoo bar, solid deodorant, sunscreen in a 100 ml tube. Liquid foundation, liquid concealer, and any liquid medication must each be under 100 ml in a single 1 L resealable bag. Solid alternatives (shampoo bar, conditioner bar, solid stick perfume) are not just compliant, they last longer.
Most hostels and budget hotels provide a basic shampoo and shower gel; pack your own for the first night and replenish on arrival from a local supermarket if you have specific needs.
Electronics
A 13-inch laptop, a phone, and a USB-C charger plus a small universal travel adapter is enough for almost any trip. Skip the bulky multi-port adapter; a USB-C 65 W charger plus one short USB-C-to-USB-C cable charges everything. A small power bank (under 10,000 mAh, allowed in cabin everywhere) covers a long travel day.
Laundry and the mid-trip reset
Plan one laundry stop per week. Most hostels have a paid washer/dryer (EUR 4–8 per load). Self-service laundromats are a clean and cheap option in any city; expect EUR 6–12 for wash and dry. Hand-wash the night before with a small bottle of camp soap; merino wool shirts dry overnight in any climate.
What you do not need to pack
- More than one week of clothing, laundry exists everywhere.
- Books, Kindle or phone reader.
- A second pair of shoes beyond your walking pair plus packable sandals.
- Travel pillow and blanket, most LCCs do not let you store one easily; rent on the plane only if you must.
- A first-aid kit larger than 5 items: paracetamol, plasters, an antihistamine, anti-diarrhoeal, and any prescription you take regularly. Anything else can be bought at any pharmacy worldwide.
