Layering is the solution. Pack a lightweight fleece or down vest that can be worn under your rain shell rather than a heavy, single-purpose winter coat.

How do I handle souvenirs?

If you buy something new, you must either mail it home or discard an old item. One-bagging requires a strict commitment to the volume of your bag.

Will I have to do laundry constantly?

Yes, but it takes 10 minutes in a sink with detergent sheets. It is a necessary trade-off for carrying only 10kg on your back.

Mastering the One-Bag Travel Method for Long-Term Trips

To travel for months with one bag, limit yourself to 40 liters of capacity and commit to washing clothes every 7 days. Use packing cubes to compress soft items and strictly follow the 'one-in, one-out' rule for every new item you acquire.

Select the right bag. Choose a 35L to 40L travel backpack that meets airline carry-on dimensions (typically 22" x 14" x 9"). Avoid bags with excessive external straps or heavy internal frames.
Adopt a base layer philosophy. Pack 7 pairs of underwear, 7 pairs of socks, and 5 shirts. Choose merino wool or synthetic blends that dry overnight; avoid heavy cotton entirely.
Use a modular packing system. Use three packing cubes: one for shirts, one for pants/shorts, and one for undergarments. This keeps your bag organized and allows you to find items without dumping your contents.
Limit footwear to two pairs. Wear your heaviest, most versatile shoes (sneakers or walking boots) on the plane. Pack one pair of lightweight sandals or flip-flops in your bag.
Digitize everything. Do not pack physical books, guidebooks, or paper documents. Store all scans of passports, insurance, and tickets in a secure cloud folder with offline access.
