Packing for a two-week trip in a single carry-on requires a disciplined "capsule wardrobe" strategy and the efficient use of space-saving tools. The golden rule is to pack clothes for one week and plan to do laundry mid-trip. Choose a color palette (e.g., navy, white, and tan) so that every top matches every bottom, allowing you to create dozens of outfits from just a few items. Wear your bulkiest items, such as a heavy jacket and boots, onto the plane to save space in the bag. Utilize compression packing cubes to organize your clothes and squeeze out excess air; many travelers find that the "rolling" method rather than folding further reduces wrinkles and maximizes volume. For toiletries, strictly adhere to the 3-1-1 liquids rule and consider switching to solid alternatives like shampoo bars and toothpaste tablets to save space and avoid leaks. By prioritizing versatile fabrics like merino wool, which resists odors and dries quickly, you can easily maintain a fresh wardrobe throughout a fourteen-day journey without the hassle of checked luggage or long waits at the baggage carousel.
