The best toiletry bags for international travel
Flying internationally changes two things about a washbag: the liquid limit is metric, and you will repack it in a different bathroom every few days. These are picked for both.

For international travel the bag to carry is a clear quart pouch for anything liquid, with a separate larger washbag for everything else - and the reason is that the limit abroad is 100 millilitres, not 3.4 ounces. They are nearly the same number and they are not the same rule: a bottle marked 3.4 oz is 100.55 ml, which is over the metric limit, and a strict screener in Europe or Asia is entitled to pull it.
The second thing that changes abroad is frequency. A two-week trip through four cities means unpacking and repacking the washbag eight times, in bathrooms that may have a single wet shelf and nowhere to put anything. A bag that hangs, wipes clean and survives a leak is worth considerably more on that trip than it is on a weekend away.
100 ml, not 3.4 oz
Buy bottles labelled 100 ml or less, not "3.4 oz". Most airports treat the two as equivalent; some do not, and the ones that do not are disproportionately outside the US. Our TSA liquid rules guide covers the US side of this in full.

The one that goes in the tray at every airport you pass through
Bagsmart Clear TSA-Approved Toiletry Bag
The single most useful thing you can do to speed up international security is keep every liquid in one clear pouch that lifts out in one movement. Screeners in Frankfurt, Narita and Heathrow all recognise this format on sight, which means less conversation and less unpacking. It is deliberately a dumb product: clear, quart-sized, and it closes properly.
The specs that decide it
- 3-1-1 status: Quart-sized and clear, which is what the rule specifies
- Abroad: Matches the 1-litre / 100 ml pattern used across Europe and Asia
- Closure: Must seal shut - an overfilled bag that will not close is a failed bag
- Use: Pack it at the top of your carry-on so it comes out in one movement
Flaws but not dealbreakers
It is only a liquids pouch. It does not hold a toothbrush, a razor, a hairbrush or anything solid, so it is half a system - you need one of the larger bags below alongside it. Clear vinyl also creases and eventually clouds.

The one that takes full-size bottles into a checked bag
Vomgomfom Silicone Waterproof Toiletry Bag (6L)
Past about ten days, decanting everything into 100 ml bottles stops working: you run out. The usual answer is full-size bottles in the checked bag, and the usual failure is a 500 ml shampoo opening at altitude. A sealed silicone case keeps that inside itself rather than inside your clothes, and the lateral buckles compress it as the contents go down, so it does not rattle around a half-empty case on the way home.
The specs that decide it
- Fabric: Silicone with a sealed waterproof main zip, so a leak stays inside
- Capacity: 6 litres - full-size 500 ml bottles fit, unlike a flat pouch
- Shape: Lateral buckles compress it as its contents empty; it folds for storage
- Not a 3-1-1 bag: Liquids still need the separate clear quart pouch
Flaws but not dealbreakers
Six litres of silicone is heavy and bulky for what it is, and it is the wrong bag entirely for carry-on-only travel - nothing in it is going through a 100 ml screen. It also has almost no internal organisation, so small items sink to the bottom.

The one for a bathroom with no counter
Bagsmart Hanging Toiletry Bag
European and Asian hotel bathrooms are frequently smaller than their American equivalents, and a great many of them have a basin with a two-inch rim and nothing else. A bag that hangs and opens into tiers turns the back of the door into your counter, and you stop losing a razor behind the cistern. The wipe-clean lining matters because this bag spends its life somewhere damp.
The specs that decide it
- Format: Hangs, and still works flat on a counter
- Lining: Wipe-clean, which is essential given what goes in it
- Pairs with: A separate clear quart pouch for the liquids
- Repacking: Tiers stay organised, so an eight-city trip stays sane
Flaws but not dealbreakers
Hanging bags are tall and thin, which is an awkward shape to fit into a packed carry-on - it tends to dictate how the rest of the bag is loaded. The hook also needs something to hang from, and plenty of bathrooms genuinely have nothing.

The ones that are genuinely under 100 ml
Humangear GoToob+ Silicone Travel Bottles
This is the pick that solves the actual international problem. At 2.5 oz these are well under 100 ml, so there is no argument to have at a European or Asian screening point, and the twist-collar lock means they do not vent into the pouch when the cabin depressurises. The writable collar panel sounds trivial until the fourth identical bottle in the bag.
The specs that decide it
- 3-1-1 status: Compliant - 2.5 oz is under the 3.4 oz / 100 ml container limit
- Abroad: About 74 ml, so no borderline-conversion problem
- Seal: LoopLock - a collar you twist to lock the cap shut
- Label: A textured panel on the collar you can write the contents on
Flaws but not dealbreakers
Being under the limit means they hold less, so on a longer trip you will run out of shampoo before you run out of trip. Silicone also retains the smell of whatever lived in it first, which is why the labels are worth using.

How the picks compare for international travel
| Pick | Goes through security | Capacity | Leak handling | Main flaw |
|---|---|---|---|---|
| Bagsmart clear pouch | Yes - recognised everywhere | 1 quart / about 1 L | Contains a small leak | Liquids only |
| Vomgomfom silicone 6L | No - checked bag only | 6 L | Sealed waterproof zip | Heavy, no organisation |
| Bagsmart hanging bag | No - dry goods | Mid-size, tiered | Wipe-clean lining | Awkward shape to pack |
| Humangear GoToob+ | Yes - about 74 ml each | 2.5 oz each | Twist-lock collar | Runs out on long trips |
The 3.4 oz versus 100 ml trap
The US rule is written in customary units - containers of 3.4 fluid ounces or less, in a one-quart bag. Most of the rest of the world writes the same rule in metric: containers of 100 millilitres or less, in a one-litre bag. 3.4 US fluid ounces is 100.55 ml. On the vast majority of trips nobody measures to the half-millilitre. But bottles are manufactured to one standard or the other, and a bottle moulded to exactly 3.4 oz is, on paper, over the European limit.
The fix costs nothing: buy bottles that state a metric figure of 100 ml or less, or buy under-limit ones like the GoToob+ above. Then the question never arises in a queue where you do not speak the language.
Why two bags beats one good one
The temptation is to buy one excellent washbag and put everything in it. International travel punishes that, because the liquids have to come out separately at every single screening point and a single bag means dismantling your entire toiletry kit on a metal table each time.
- Clear quart pouch - every liquid, gel, cream, paste and aerosol. Lives at the top of the carry-on.
- Dry bag - toothbrush, razor, brush, medication in its box, contact case, nail clippers. Never comes out at security.
- Checked case (long trips only) - the full-size bottles, inside something sealed.
The full packing method, including the order things go into the bag, is in how to pack toiletries.
The solids workaround
The quart pouch is a fixed-size container, and the easiest way to fit more into it is to put less in it. A shampoo bar, a conditioner bar and toothpaste tablets are not liquids under any screening regime on earth, so they ride in the dry bag and free up the pouch for the things that genuinely must be liquid - sunscreen, contact solution, medication.
On a three-week trip that single swap is often the difference between carry-on-only and checking a bag. Solid toiletries for travel covers what works and what is marketing.
Medication and the exemptions
Prescription liquids, baby formula and breast milk are exempt from the 100 ml limit in most jurisdictions, but the exemption is conditional on declaring them. Keep them separate from the quart pouch, in their original labelled packaging, and say so before the bag goes on the belt rather than after.
Carry a copy
For anything prescribed, a photograph of the prescription on your phone resolves almost every question in seconds. It is also what you will need if a pharmacy abroad has to replace it.
