8 Best Bags for International Travel

Where our top pick is shaped around a strict under-seat footprint, the Lumesner assumes you want the space instead, and for a trip that runs a week or more we think that is the right trade. Four packing cubes come in the box — a large one for sweaters and trousers, a medium for shirts, a small water-resistant one for toiletries, and a shoe bag — so the organization arrives with the bag rather than as a separate purchase.

The expansion zip does real work. Closed, it is a tidy weekend pack; unzip it and there is 40 liters of room for a week of clothes plus whatever you buy on the way. Internal compression straps keep the load from sliding when the bag is only half full, and the USB pass-through on the side is the sort of feature you use twice and then forget about entirely.

We paid close attention to the hardware, because a pack this size gets lifted by a handle far more often than it gets worn. The strap anchors and the top grab handle take the strain when the bag is full, so we carried it by the shoulder straps on the heavy legs and saved the grab handle for lifting it into an overhead bin. The multi-panel padding and sternum strap make a difference on a long walk between gates.

Packed light and worn high, it carries better than its weight suggests; packed to the expansion, it is a bag you set down whenever you stop rather than keep on your back. The cubes are also the part that lasts — pull them out at the hotel and the pack flattens into a wardrobe drawer.

A zipped panel across the back swallows the shoulder straps, and that one detail keeps this pack in rotation in a way a standard backpack does not. Worn normally it is an ordinary bag with padded straps, an air-mesh back panel and a sternum strap; flatten the harness, grab the top and side handles, and it carries like a duffel you can slide under a train seat without a strap dragging on the floor.

Capacity is the other argument. It runs at 40 liters with the expansion zip shut and takes 45 when you open it, which is enough for a two-week trip if you plan a laundry stop, and the padded compartment swallows a 17-inch laptop. The front pocket is small and quick for a phone and a passport, and the zipper heads lock together if you carry a small padlock. The main body also has internal compression straps, which matter more than the pocket count once the bag is full.

We think this is the best of these for a trip whose shape changes mid-way: a few days of work in one city, then a week of trains. The one thing we watch is where the load hangs — the top handle and the strap anchors take the strain when it is packed — so we carried it by the side handle on the heavy legs and saved the top grab for lifting it into the bin.

At 0.79 kg — 1.74 pounds — this is the lightest backpack in the set, and on carriers that weigh cabin bags at the gate that is the number deciding whether you pay extra. The 16.8-inch length and seven-inch depth also clear under-seat spaces that take a 20-inch pack only if you empty half of it first. For a short international trip on a budget airline, that combination is the whole argument.

What we think makes it worth a place is how much fits into a bag this small and this light. Three main compartments and nine pockets, including a dedicated shoe bag and a wet pocket, mean the organization is already there; the padded sleeve takes a 15.6-inch laptop; and the two padded handles let it hang off a shoulder or a luggage cart when the straps get tiresome. It is also the least expensive backpack here, which matters for a bag that will spend time on bus floors and hostel bunks.

The catch is durability. Shell and strap durability are the weakest in this group, so buy it for a trip rather than a decade, and the hand-wash-only care instruction rules it out for anywhere muddy. Packed within its limit rather than to the seams, it does several international trips without complaint, and the wet pocket earns its keep on the last day when everything else is clean.

The wet pocket sells this one for us: a water-resistant lined compartment that takes a damp swimsuit or a towel without soaking everything else, which is the sort of thing you appreciate on day two of a beach trip rather than day one. Add a 21.65 by 10.63 by 7.09-inch body slim enough to sit on your lap in a departure lounge, and this is the duffel we take as a second bag rather than a second suitcase.

The trolley sleeve is the other reason it travels well: it slides over a rolling case handle and rides there through the airport rather than slipping off your shoulder every fifty paces. Six pockets, a removable adjustable strap, and water-resistant fabric that shrugs off a drizzle round it out. The exterior is soft enough that it squashes into an overhead bin even when it is full.

Capacity is a weekend’s worth, honestly — a night or two of clothes, a pair of shoes in the main compartment, a toiletry bag on top. The bag has no structure of its own, so pack it flat and full or it slumps in the corner of a hotel room. Neither bothers us for the job it does: it is the bag that keeps your essentials with you while the roller goes in the bin.

This is the bag that folds into its own pouch: 40 liters down to something the size of a paperback, which is why it lives in the bottom of a suitcase rather than on a closet shelf. It weighs 1.2 pounds empty, so bringing it along costs you almost nothing in weight or space — and it is the difference between cramming souvenirs into a carry-on and checking a bag home.

Opened up, it is a proper duffel: a vented shoe compartment at one end, a trolley sleeve on the back, and shoulder straps that tuck into a panel so it can be worn through a station or carried by hand once you are there. Two ways to carry sounds like marketing until you are on a ferry with both hands full of coffee and tickets.

We think this is the best second bag in the set, and it is the one we pack empty on the way out and fill on the way home. What it is not is structured: the polyester is light, the base is soft, and a half-packed bag collapses into itself on the floor — pack it full or hang it up. Also check your carrier’s sizer before using it as a main cabin bag rather than checked luggage.

The shoe compartment is the point of this duffel: a flat, separate zipped base that takes trainers or a bag of dirty laundry, with a matching toiletry bag thrown in. If you have ever opened a weekender to find a sandal print across a white shirt, you know why that matters more than the pocket count.

The numbers suit a personal item: 20.5 by 8.5 by 12.7 inches, 35 liters, 1.7 pounds, with a removable padded shoulder strap, rounded grab handles and a band that slides over a rolling case handle. The main compartment takes three to five days of clothes if you roll them, and the toiletry bag means one less thing to buy before you leave.

The shoe space comes out of the clothing side, though: pack two pairs and the main compartment loses roughly the volume of a folded jumper. The bag also has no frame, so it stands up when it is full and folds in on itself when it is not, which is a small annoyance in a hotel wardrobe and not much more.

We rate it as the tidy short-trip duffel of this group rather than a main bag for a long haul. The organization is better than the rest of the bag, and the separate base is worth the space it costs on a two-night trip. For anything longer, one of the 40-liter backpacks here is the better shape.

One hundred liters is not a carry-on, and no amount of packing skill changes that: at 31.89 by 11.81 by 16.14 inches, this duffel is a checked bag. The reason to own it anyway is the flight home, when the suitcase is full and the things you bought are not.

It folds down to about 13.78 by 13 by 1.77 inches and 1.7 pounds, so it disappears into the bottom of a case on the way out. Open it and there is a shoe compartment at one end, an internal pouch, several pockets, a removable shoulder strap and a sleeve that slides over a luggage handle. The honeycomb nylon is water-repellent, which is enough for a suitcase hold and a walk to the terminal.

The same 210D nylon is thin, and this is a bag that survives because it is light rather than because it is armored. Carry it by the handles instead of dragging it, and do not expect it to hold a shape: full, it sags in the middle, and an unsupported base means the load shifts when you lift it. That is the price of a bag that folds to under two inches.

Our advice is simple: buy it as the overflow bag, not the bag. It goes into your luggage empty, comes out when the shopping exceeds the suitcase, and gets checked on the return. If you want one bag that does the entire trip, the LOVEVOOK or the Lumesner is the better place to spend your money.
