I once watched a woman in the Lisbon airport try to maneuver a 28-inch suitcase, a carry-on, a tote bag, and a handbag through a narrow turnstile. She got stuck. Her suitcase tipped over. Her tote bag slid off her shoulder, spilling souvenirs across the floor. I was standing next to her with a single 40-liter backpack, and the contrast was so stark that it felt like a parable. That was three years ago. I have not checked a bag since, and I have never been more comfortable while traveling.

The Backpack That Changed How I Travel
After years of experimenting with different bags, I settled on the Osprey Farpoint 40 as my one and only travel bag. It is a 40-liter backpack that meets the carry-on size requirements for virtually every airline in the world, including the strict European budget carriers like Ryanair and EasyJet. The front-loading design, similar to a suitcase, means you do not have to unpack everything to reach an item at the bottom. The padded hip belt distributes weight effectively when you are walking long distances with it fully loaded. It costs about 140 dollars, and I have used mine for over 200 days of travel across four continents without any signs of wear.
This reason 40 liters works is not because I am some kind of ascetic who owns nothing. It works because I follow a strict system for every item I pack. Every piece of clothing must work in at least three different outfits. Every item must have a specific purpose that I have used on a previous trip. Every "just in case" item is eliminated unless I can recall a specific trip where I genuinely needed it. This system is not about deprivation. It is about removing decision fatigue. When you have fewer things, you spend less time choosing what to wear, less time packing and unpacking, and less time worrying about your belongings.
If a backpack is not your style, the Aer Travel Pack 3 is an excellent alternative. It is a soft-sided carry-on that functions as both a backpack and a duffel bag, with a clamshell opening and a built-in garment folder. It costs about 295 dollars, which is significantly more expensive than the Osprey, but the build quality and organization system are exceptional. For pure carry-on suitcase users, the Away Carry-On at 295 dollars and the Monos Carry-On Pro at 310 dollars are both well-designed options with built-in batteries for charging devices. The key, regardless of which bag you choose, is to commit to a single carry-on sized bag and refuse to check anything.
My Complete Clothing Packing List
Here is exactly what I pack for a two-week trip to a warm or temperate climate, which is my standard template. I adjust for cold weather by adding a merino wool base layer and a warmer jacket. Tops: three merino wool t-shirts in neutral colors, one short-sleeve linen shirt, one long-sleeve button-up that can be worn open as a light layer. Bottoms: one pair of dark slim-fit pants that work for both daytime exploration and nicer dinners, one pair of lightweight hiking pants, one pair of running shorts, and one swimsuit. Outerwear: one lightweight packable down jacket from Uniqlo that compresses to the size of a water bottle, one rain jacket. Underwear and socks: five pairs of ExOfficio Give-N-Go underwear, which are quick-drying and can be washed in a sink and dried overnight, and four pairs of Darn Tough merino wool socks. Shoes: one pair of Allbirds Tree Runners for everyday use, one pair of Teva Original Universal sandals for water activities and hot weather.
A total clothing count is roughly 14 items, and they all fit in one packing cube. I use the Peak Design Packing Cube, which has a zippered clamshell design and compression straps. It costs about 60 dollars and is the single best packing accessory I own. Every item of clothing goes into this one cube, which then slides into my backpack like a drawer. When I arrive at my accommodation, I unzip the cube and place it in a drawer or on a shelf. I never have to unpack individual items, and repacking takes about two minutes.
One merino wool t-shirts deserve special mention because they are the foundation of my packing system. Merino wool regulates temperature in both hot and cold weather, resists odors for days without washing, dries quickly, and packs down to almost nothing. I wear Icebreaker 200 Oasis t-shirts, which cost about 80 dollars each but last for years. I can wear the same merino t-shirt for three to four days in a row without it smelling, which means I only need three t-shirts for a two-week trip. Compare that to cotton t-shirts, which need to be washed after every wear and take much longer to dry. The upfront cost is higher, but the space and weight savings are enormous.
Traveler's Tip
Before your trip, wear your bulkiest items on the plane. Your hiking shoes, your down jacket, and your heaviest pants should be on your body, not in your bag. This simple trick can save 30 to 40 percent of your bag's volume and weight, and it keeps you warm on cold flights.
Electronics: Minimal but Essential
My electronics kit has been refined over years of travel to include only what I actually use. Phone: an iPhone 15 Pro with 256GB of storage, which serves as my camera, navigation tool, translation app, notebook, and entertainment device. Charger: an Anker Nano II 65-watt GaN charger that weighs 105 grams and can charge my phone, my laptop, and my camera battery simultaneously. Cable: one USB-C to USB-C cable and one USB-C to Lightning cable. Power bank: an Anker PowerCore 10000 that weighs about 180 grams and provides roughly two full phone charges. Headphones: Sony WF-1000XM5 earbuds for noise cancellation on flights and buses. Laptop: an M2 MacBook Air, which I only bring if I am working remotely. Camera: a Ricoh GR IIIx, a compact fixed-lens camera that fits in a jacket pocket and takes extraordinary photos.
The total electronics kit, excluding the laptop, weighs about 800 grams and fits in a single Tom Bihn Tech Organizer that costs about 35 dollars. This organizer has elastic loops for cables, mesh pockets for small items, and a clear panel that lets you see everything at a glance. It eliminates the frustration of digging through your bag for a specific cable or adapter. I keep this organizer in an easily accessible pocket of my backpack so I can grab my charger or headphones without unpacking anything.
One item I no longer bring is a dedicated e-reader. I used to carry a Kindle, but I found that I was reading on my phone anyway, and the Kindle added unnecessary weight. If you read extensively, a Kindle Paperwhite at 130 dollars and 174 grams is still the best option for travel reading. Its battery lasts for weeks, its screen is readable in direct sunlight, and it holds thousands of books. But if you are a casual reader like me, your phone is sufficient. The one tech item I always bring that most people forget is a universal plug adapter. I use the Epicka Universal Power Adapter, which costs about 25 dollars and works in over 150 countries. It has two USB-A ports, one USB-C port, and one AC outlet, allowing you to charge four devices simultaneously from a single wall socket.
Toiletries and Personal Care
The toiletry kit is where most travelers overpack by the widest margin. Full-size bottles of shampoo, conditioner, and body wash are the enemy of light packing. I use a combination of solid toiletries and small reusable containers to keep my kit compact. Shampoo and body wash: a solid shampoo bar from Ethique, which costs about 12 dollars, lasts for 80 to 100 washes, and weighs nothing. One bar replaces both liquid shampoo and body wash. Deodorant: a solid deodorant stick from Native, which comes in a small cardboard tube and weighs about 50 grams. Toothbrush: a bamboo toothbrush from Brush with Bamboo that weighs about 15 grams. Toothpaste: a small tube from any brand, transferred into a GoToob silicone container that holds about 30 milliliters.
Sunscreen is the one toiletry I never compromise on. I carry a 100-milliliter tube of Supergoop Unseen Sunscreen SPF 40, which costs about 22 dollars, applies clear, and works well under makeup if you wear it. In countries where sunscreen is expensive or hard to find, I bring a second tube as backup. Insect repellent is another essential for tropical destinations. I use the Sawyer Premium Insect Repellent with 20 percent picaridin, which comes in a 3-ounce spray bottle that is TSA-approved. It costs about 8 dollars and is effective against mosquitoes, ticks, and sand flies for up to 12 hours.
All of my toiletries fit into a single Sea to Summit Ultra-Sil Dry Sack, which is a lightweight waterproof bag that costs about 15 dollars and weighs 18 grams. I hang this bag on a hook in the bathroom when I arrive, and everything is accessible without unpacking. The total weight of my toiletry kit, including sunscreen and insect repellent, is about 350 grams. Compare that to the average traveler's toiletry bag, which weighs 1 to 2 kilograms and includes items that are available at any pharmacy in the world. The only items you truly need to bring from home are prescription medications, contact lenses, and any specific products that are difficult to find abroad.
Documents and Money Essentials
My document organization system is simple but thorough. I carry a slim passport holder from Bellroy that costs about 90 dollars and holds my passport, two credit cards, a debit card, some folded cash, and a SIM card ejector tool. I keep a photocopy of my passport, travel insurance policy, and credit card numbers in a separate location, usually tucked into my backpack's internal pocket. I also store digital copies of all documents in a password-protected folder in Google Shape, accessible from my phone even without internet if I have downloaded them in advance.
For money, I carry two credit cards with no foreign transaction fees: a Chase Sapphire Preferred and a Capital One Venture X. I keep them in separate locations, one in my wallet and one in my backpack's hidden pocket. I also carry about 100 dollars in US dollars as emergency cash, hidden in a zippered pocket. For local currency, I withdraw from bank-affiliated ATMs upon arrival using my debit card, which has a 3-dollar foreign transaction fee but offers excellent exchange rates. I avoid airport currency exchanges entirely, as they typically charge 7 to 15 percent above the actual exchange rate. I withdraw enough local currency for two to three days at a time, which minimizes fees while reducing the risk of carrying too much cash.
Travel insurance is non-negotiable. I use Safety Wing, which costs about 45 dollars per month and covers medical emergencies, evacuation, trip interruption, and lost belongings. It is designed for long-term travelers and can be purchased or canceled at any time. For shorter trips, World Nomads offers Complete coverage for about 5 to 10 dollars per day. I have used travel insurance twice: once for a 300-dollar doctor visit in Bali and once for a 500-dollar flight cancellation in Colombia. Both claims were processed within two weeks. The peace of mind alone is worth the cost, and the two times I actually needed it, it paid for years of premiums.
The One-Bag Philosophy: Why Less Really Is More
The practical benefits of one-bag travel are obvious: no checked bag fees, which save 30 to 60 dollars per flight; no waiting at baggage claim, which saves 20 to 45 minutes per flight; no risk of lost luggage, which eliminates one of the most stressful travel experiences; and no lugging a heavy suitcase up narrow staircases, across cobblestone streets, or onto crowded trains. But the psychological benefits are even more significant. When you carry everything you own on your back, you feel a sense of self-sufficiency that changes how you relate to travel. You can change your plans at a moment's notice because you do not need to retrieve checked bags or repack a large suitcase. You can walk from the airport to your accommodation instead of paying for a taxi. You can Explore a crowded metro at rush hour without cursing your rolling suitcase.
I have traveled with people who checked large suitcases, and the difference in our daily experience was striking. While they waited at baggage claim, I was already on my way into the city. While they struggled to maneuver their bags through narrow hotel corridors, I walked freely. While they paid 15 euros to store their luggage on their last day because their flight was in the evening, I carried my bag to a museum, a cafe, and a park, and checked in for my flight with zero hassle. Over a two-week trip, these small advantages accumulate into a fundamentally different and, in my experience, better travel experience.
Often the most common objection I hear is "but what if you need something you did not pack?" In three years of one-bag travel across 30-plus countries, I have needed to buy something I did not pack exactly twice: a warmer sweater in Patagonia, which cost 25 dollars at a local market, and a pair of hiking socks in Nepal, which cost 3 dollars. Both purchases took five minutes and became souvenirs. The cost of occasionally buying something on the road is vastly lower than the cost of dragging around items you never use for the entire trip. Pack light, travel far, and trust that the world has stores.
