How to pack for a two-week trip in a single backpack

Stick to a 35-40 liter carry-on backpack and follow the 'rule of three' for clothing. By laundering items midway through your trip, you can travel indefinitely without needing a checked bag.

  1. Select the right bag. Use a 35-40 liter backpack with a clamshell opening. If the bag is larger than 45 liters, you will be tempted to overpack and risk carry-on size rejection at the gate.
  2. Use the rule of three. Pack 3 shirts, 3 pairs of underwear, and 3 pairs of socks. Wear one set, wash one set in the sink or laundry, and keep one set clean as a backup.
  3. Prioritize layering. Pack clothing that functions in layers rather than one heavy jacket. Bring one base layer, one mid-layer (fleece or sweater), and one packable wind/rain shell.
  4. Compress everything. Use compression packing cubes to reduce the volume of your clothes by 30%. Roll your clothes tightly before placing them into the cubes.
  5. Limit footwear. Bring only two pairs of shoes total: one pair of versatile sneakers worn on the plane, and one pair of lightweight sandals or flat shoes packed in the bag.
What if I need an outfit for a formal event?
Choose a 'base' color palette (black, navy, or grey) for your entire wardrobe so everything matches. A simple dark shirt and pants can serve as both daily and formal wear.
Does my backpack count as a personal item?
A 40L bag is usually a carry-on. If you are worried about airline weight limits, wear your heaviest items (boots and jacket) onto the plane to save space and weight.
How do I handle dirty laundry?
Pack a small, ultralight dry bag or a dedicated laundry pouch to keep dirty clothes isolated from the rest of your clean items.
