How to Pack Everything You Need in a Single Carry-On

Stick to a strict 40-liter bag limit and use a capsule wardrobe centered on a neutral color palette. By limiting yourself to one pair of shoes and using compression packing cubes, you can move through multiple countries without ever needing to check a bag.

Step by step

  1. Select the right bag

    Choose a soft-sided backpack that measures 22 x 14 x 9 inches (56 x 35 x 23 cm). Hard-shell rollers are heavier and less versatile when moving through cobblestone streets or boarding regional trains.

  2. Curate a capsule wardrobe

    Bring no more than 7 days of clothing, regardless of your trip length. Use a color scheme where every top matches every bottom. Focus on merino wool or synthetic fabrics that dry overnight if washed in a sink.

  3. Master the compression method

    Fold clothes tightly or roll them, then place them into compression packing cubes. These cubes remove air and reduce the volume of your clothes by 30-40%.

  4. Wear your bulk

    Always wear your heaviest items—boots, thickest jacket, and heaviest sweater—on the plane. This saves critical space and weight inside your bag for destination-specific layers.

  5. Consolidate liquids

    Transfer all toiletries into 3-ounce (100ml) silicone squeeze bottles. If you run out, buy replacements at local grocery stores rather than packing full-sized containers from home.

Questions people ask

What if I run out of clean clothes?

Most hostels and many hotels provide laundry facilities. Alternatively, pack a small travel-sized packet of detergent and wash basics in your bathroom sink; they will dry by the next morning if you use synthetic fabrics.

How do I handle souvenirs?

If you plan to shop, bring a lightweight, foldable duffel bag that fits inside your carry-on. You can fill this as a 'personal item' on your flight home if you end up with more than you started with.

Notes
Expect to spend between $150 and $300 on a high-quality carry-on backpack. Once purchased, you save money on checked bag fees which average $30-$50 per flight.
