Quick answer
Use two bags: a clear 1-quart bag or cube for liquids you’ll carry through security, and a toiletry pouch for everything else. Under TSA’s 3-1-1 rule, each liquid must be 3.4 oz (100 ml) or less and all must fit in one quart-size bag. From our research, the TOM BIHN 3D Clear Organizer Cube is a durable 1-liter liquids bag, and the Peak Design Wash Pouch is a well-built hanging kit for the rest.
The rules that shape your toiletry kit
- Liquids, gels and aerosols in carry-on bags must be in containers of 3.4 oz (100 ml) or less, all fitting in one quart-size bag per passenger (TSA).
- Solid toiletries aren’t liquids: solid deodorant (TSA) and bar soap (TSA) are allowed in carry-on bags outside the liquids bag.
- Medications and baby formula are exempt in reasonable quantities but must be screened separately. See our TSA rules guide.
Go solid to save space
Swapping liquid shampoo, soap and deodorant for solid versions frees up room in your quart bag.

What to look for
- Hook or stand-up base: useful in small bathrooms with little counter space.
- Water resistance: a coated or weatherproof fabric protects your bag if something leaks.
- Size: big enough for your routine but not so big you overpack.
- A separate clear liquids bag makes security faster.
Toiletry checklist
- Toothbrush, toothpaste (3.4 oz or less for carry-on) and floss
- Solid or travel-size deodorant
- Shampoo and conditioner (solid bars save space)
- Skincare and sunscreen
- Medication in original packaging
- Razor (cartridge razors are fine in carry-on; check TSA rules for blades)
- Small first-aid items
