The Best Travel Toiletry Bottles: 4 Compared (and One to Skip)
Four refillable bottle and capsule systems compared on stated capacity against the 3.4 oz carry-on limit, on what each maker tells you not to put inside, and on how each one is cleaned.
The short version
The humangear GoToob+ 3-Pack is the pick for most carry-on packers: silicone squeeze tubes in 1.7, 2.5 or 3.4 fl oz, a locking cap, a lifetime warranty, and the most detailed published compatibility list of the four. The Nalgene Travel Kit with Bag is the value choice, with four 2 oz bottles, a jar, a vial and a bag, all described as leakproof and dishwasher safe, though Nalgene does not publish the plastics on the product page. Cadence Capsules suit people who carry creams, serums and oils in small amounts, because the largest capsule holds 2.75 fl oz and they are jars you scoop from, not bottles you squeeze. Skip the Ries Essential for flying, because Ries itself does not recommend taking flight with water-thin products or oils in it and advises caution with anything less viscous. Whatever you buy, humangear recommends putting the bottles in a sealed zip bag as insurance, which the quart bag already does. Best for: carry-on travelers who decant their own shampoo, lotion and skincare and want to know what each container can and cannot hold.

The verdict in 30 seconds
What mattered most
- Container type
- Stated capacity
- Closure as described by maker
- Contents the maker warns about
- Stated material
- Material claims
The TSA limits carry-on liquids to containers of 3.4 ounces (100 milliliters) or less, all inside one quart-sized bag, so the first check on any travel bottle is its stated capacity. The second check is one most buyers never make: the maker's own list of contents that do not belong in it. Silicone squeeze bottles, rigid plastic bottles, magnetic capsules and airless pumps each come with a different list, and the lists are published if you look. We picked one of each type and read the manufacturer pages for what they state and what they leave out.
Silicone squeeze tubes with a locking cap, sold in three sizes that top out exactly at the 3.4 fl oz carry-on limit.
Best for: Travelers decanting ordinary shampoo, conditioner, body wash and lotion who want a squeeze bottle with a cap that locks.
- humangear states single-tube capacities of 1.7 fl oz (Small), 2.5 fl oz (Medium) and 3.4 fl oz (Large), so every size sits at or under the TSA limit.
- The LoopLock locks the flip cap closed, and humangear describes the tube as contoured so it can stand for filling.
- Tubes and collars are stated as dishwasher safe on the top rack, and the material is listed as BPA-free, phthalate-free, FDA food-safe silicone.
- humangear recommends against salicylic acid products, hair serums and shine treatments including argan oil products, sterile fluids such as contact lens solution, and caustic or flammable products.
- Alcohol-based products, sunscreens, liquid sweeteners and skin conditioning oils are on a test-overnight-first list, and humangear says alcohol slowly evaporates through the silicone.
- The flip caps are hand-wash only.
- humangear says the tubes are designed for travel, not long-term storage, and some fluids can dry out over months.
Six rigid containers and a bag in one inexpensive kit, with every bottle well under the carry-on limit.
Best for: Occasional flyers and budget packers who want a complete, dishwasher-safe set in one purchase.
- Nalgene lists four 2 oz square bottles, one 1 oz jar and one 1 oz vial, so the kit covers liquids, thick creams and small dry items.
- Nalgene describes the bottles as leakproof and gives them color-coded caps for telling contents apart.
- The product page states the kit is safe to put in the dishwasher, with a listed kit weight of 3.52 oz (99.75 g).
- The product page does not publish the plastics used, a BPA statement or a list of contents to avoid.
- Capacities are given in ounces only, with no milliliter figures on the page.
- Rigid bottles do not shrink as they empty and are harder to get the last of a thick product out of than a squeeze tube.
- At 2 oz the largest bottle holds less than a 3.4 fl oz tube, so long trips may need refills.
Magnetic, hard-walled screw-top jars for small amounts of skincare, with the fewest content restrictions of the four and the smallest capacities.
Best for: Skincare-heavy packers who carry serums, facial oils, creams and pills in small quantities and are willing to pay for a system.
- Cadence states the Capsules can be filled with any product including oils, and says the material is non-porous, BPA and PFA-free and non-leaching.
- The threaded cap takes two and a half rotations to close, and Cadence backs every Capsule with a Lifetime Leakproof Guarantee.
- Magnets on the top, bottom and sides (Medium and Large) hold the set together, and interchangeable tile labels identify the contents.
- Stated capacities are 0.56 fl oz (Small), 1.32 fl oz (Medium) and 2.75 fl oz (Large), and the Starter Set includes only three Medium and three Small.
- They are jars, not squeeze bottles, so shampoo and body wash have to be scooped or poured.
- Cadence says pure essential oils should not be left in for more than a month, and that formulas with iron oxides can separate near the magnets.
- Cadence's cleaning instructions describe hand washing with mild soap; dishwasher use is not published on the pages we read.
A good-looking airless pump bottle whose own maker does not recommend flying with water-thin products or oils in it.
Best for: Road trips and bathroom shelves, or flyers whose entire kit is thick creams and gels.
- The Original holds 3.4 oz (100 ml) per Ries, with the size embossed on the base, and a 1.7 oz (50 ml) size is also sold.
- Ries describes it as silicone-free, BPA-free and made of a recycled plastic resin, with an airless pump that restricts air flow to the product.
- Ries says the bottles are dishwasher safe on the top rack, though it recommends hand washing for best results.
- Ries states it does not recommend taking flight with water (micellar water, contact lens solution) or oil (body oil) in the bottle.
- Its FAQ advises caution when flying with very oil-based, water-based or less viscous products because leaks can occur under cabin pressure.
- Ries says four of the 3.4 oz bottles fit snugly in a quart-size bag, which leaves little room for anything else.
- Premium pricing for a bottle the maker positions mainly for thicker lotions, creams, gels and soaps.

How we judged the field
Five things decide a travel bottle. First is stated capacity, because the TSA limit of 3.4 ounces (100 milliliters) applies to the container and a bottle over it does not fly in a carry-on. Second is the maker’s compatibility list, since silicone in particular reacts with some products and the careful makers say which. Third is the closure, as described by the maker: a valve, a lock, a threaded cap or a pump each fail differently. Fourth is cleaning, because a bottle you cannot wash properly carries last trip’s conditioner into this trip’s face wash. Fifth is what the maker publishes about materials, and we repeat those claims only as written.
The field splits into four types: silicone squeeze tubes, rigid plastic bottles, magnetic capsule systems and airless pumps. We picked one well-known example of each so the comparison is between designs and not between near-identical sets. The humangear GoToob+ represents silicone, the Nalgene kit represents rigid bottles, Cadence represents capsules and Ries represents the airless pump. Many low-cost silicone sets are sold without a manufacturer page that states materials or compatibility, which is why none of them is here.
The GoToob+ is a silicone squeeze tube with a polypropylene flip cap and a silicone valve in the cap. humangear sells the 3-pack in Small (1.7 fl oz), Medium (2.5 fl oz) and Large (3.4 fl oz), with single-tube dry weights of 45, 50 and 65 grams, so the Large sits exactly at the carry-on limit and the others below it. The LoopLock is the detail that sets it apart: a loop that locks the flip cap shut so it cannot pop open in a bag. Tubes and collars go in the top rack of the dishwasher, caps are washed by hand, and the whole thing carries a lifetime warranty. The trade-off is silicone itself. humangear publishes a list of products it recommends against, including salicylic acid treatments, hair serums and argan oil products, and it says alcohol slowly evaporates through the tube wall. It also recommends a sealed zip bag as insurance. That candor is a reason to trust it. This is the bottle for people decanting everyday shampoo, conditioner, body wash and lotion.
Nalgene’s Travel Kit with Bag takes the opposite approach to a squeeze tube: rigid containers with screw caps, sold as a complete set. The product page lists four 2 oz square bottles, one 1 oz straight-sided jar for pills or thicker gels and lotions, and one 1 oz vial sized for cotton swabs, with color-coded caps and a bag. Nalgene describes the bottles as leakproof and the kit as safe to put in the dishwasher, and lists the weight at 3.52 oz (99.75 g). What the page does not give you is the plastic each piece is made from, a BPA statement, milliliter capacities, or any guidance on contents to avoid. That absence matters less for shampoo than for an expensive serum. Rigid bottles also keep their full size when half empty, and a thick conditioner is slower to get out than from a tube. For the money, though, you get six containers and somewhere to put them. It is for budget packers and occasional flyers who want the job done in one purchase.
Cadence Capsules are hexagonal, hard-walled jars with magnets that snap them into a block. Cadence states capacities of 0.56 fl oz for the Small, 1.32 fl oz for the Medium and 2.75 fl oz for the Large, and the Starter Set is three Medium and three Small with preset labels. The pitch is material: Cadence says the Capsules are non-porous, BPA and PFA-free, made with 50% recycled material, and can be filled with any product, including the oils and serums silicone makers warn about. The cap takes two and a half rotations and there is a Lifetime Leakproof Guarantee. The limits are capacity and format. A Medium holds about half of a Medium GoToob+, and you scoop or pour from a jar. Cadence also notes pure essential oils should not sit for more than a month, that iron oxide makeup can separate near the magnets, and that the magnets can occasionally flag a scan. It is premium priced. Buy it if your liquids are mostly small-dose skincare, not a week of shampoo.
The Ries Essential is the most stylish thing here: a rigid 3.4 oz (100 ml) bottle, 5.3 by 1.8 inches, with a patented airless pump and a twist-to-lock outer cap. Ries describes it as silicone-free so it will not interfere with silicone-based haircare, BPA-free, made of a medical-grade recycled plastic resin, and dishwasher safe on the top rack. For thick shampoo, conditioner, creams and gels it does what it says. The problem is the fine print for flying, which is the whole reason most people buy a travel bottle. Ries states it does not recommend taking flight with water, such as micellar water or contact lens solution, or with oil, such as body oil, and its FAQ advises caution with any less viscous product because leaks can occur under cabin pressure. Ries also says only four of the 3.4 oz bottles fit snugly in a quart bag. At a premium price, a carry-on bottle that the maker restricts in the air is hard to recommend. It suits road trips and thick products only.
humangear GoToob+ 3-Pack vs Nalgene Travel Kit with Bag: which should you buy?
The GoToob+ and the Nalgene kit solve the same problem from opposite ends. The GoToob+ is a soft tube that you squeeze, with a valve in the cap and a lock over it, and humangear tells you its capacity, weight, materials, cleaning method and the products to keep out of it. The Nalgene kit is a set of rigid screw-cap containers with a bag, described as leakproof and dishwasher safe, with very little else published on the product page.
Choose the GoToob+ if you travel often, want to get the last of a thick product out, and are decanting ordinary hair and body products that are not on humangear’s avoid list. Choose the Nalgene kit if you fly a few times a year, want a jar and a vial as well as bottles, or want everything to go through the dishwasher without sorting caps from tubes. If your bag is full of serums, hair oils or acne treatments, humangear’s own list points you away from silicone, and a rigid container is the safer default.
What to look for
- Stated capacity: Look for a figure of 3.4 fl oz or 100 ml or less per container, printed by the maker, since that is the TSA carry-on limit.
- Compatibility list: A maker that names the products to avoid, as humangear does for salicylic acid and hair serums, is giving you information the others are withholding.
- Closure design: A locking cap, a multi-turn thread or a locking pump is a described mechanism; the word leakproof on its own is not.
- Cleaning method: Check which parts are dishwasher safe, because it is often the body and not the cap.
- Material claims: Treat BPA-free and food-safe as true only where the maker states them, and note when a product page says nothing.
- Format for your products: Squeeze tubes suit shampoo and lotion, jars suit creams and pills, and pumps suit thick products the maker approves for flight.
Our final take
Start with what you carry. For everyday shampoo, conditioner, body wash and lotion, the humangear GoToob+ is the one to buy: three sizes up to the 3.4 fl oz limit, a locking cap, a lifetime warranty and a maker that tells you plainly what silicone does not get along with. The Nalgene Travel Kit with Bag does the basic job for less, with six rigid pieces and dishwasher cleaning, as long as you accept a thin spec sheet. Cadence Capsules make sense for small amounts of serums, oils and creams at a premium. Skip the Ries Essential for air travel, because its own maker advises against flying with thin liquids or oils in it. Then seal the quart bag.
Questions, answered
How big can a travel bottle be for carry-on?
The TSA allows liquids, aerosols, gels, creams and pastes in carry-on bags only in containers of 3.4 ounces (100 milliliters) or less per item, and they all have to fit in one quart-sized bag. The limit applies to the container, so check the capacity the maker states. Here, the humangear GoToob+ Large is 3.4 fl oz, the Ries Original is 3.4 oz, the Nalgene bottles are 2 oz and the largest Cadence Capsule is 2.75 fl oz. Other countries set their own rules, so check the airport you are flying from if it is outside the United States. Larger containers belong in checked baggage.
What should I not put in a silicone travel bottle?
It depends on the maker, and the careful ones publish a list. humangear recommends against using the GoToob+ for products with salicylic acid, hair serums and shine treatments including argan oil products, sterile fluids such as contact lens solution, and caustic, corrosive or flammable products. It puts alcohol-based products, liquid sweeteners, sunscreens and skin conditioning oils on a second list to test overnight before a trip. humangear says you will know a product is incompatible if it leaks, changes the shape or color of the tube, evaporates or dries up. If your kit is mostly serums and oils, a non-silicone container is the simpler choice.
Are travel bottles really leak-proof on a plane?
Makers describe their closures confidently, and the more careful ones still tell you to bag the bottles. humangear says GoToob+ tubes will not leak under normal circumstances and recommends a sealed zip bag anyway, because caps get left loose and luggage gets crushed. Cadence offers a Lifetime Leakproof Guarantee on its Capsules and describes a threaded cap plus a seal. Ries says leaks can occur with thin products because of cabin pressurization. Since carry-on liquids already travel in a quart bag, the insurance is built in if you seal it.
Can I put travel bottles in the dishwasher?
Sometimes, and usually not every part. humangear states GoToob+ tubes and collars are dishwasher safe on the top rack while the flip caps should be hand washed. Nalgene lists its travel kit as safe to put in the dishwasher. Ries says top rack only and recommends hand washing for best results. Cadence describes hand cleaning with mild soap and warm water and does not publish dishwasher guidance on the pages we read.
Do I still need a toiletry bag if I buy a bottle set?
For the airport, the liquids have to go in one quart-sized bag, and the Nalgene kit is the only one of these four that includes a bag of its own. Nalgene does not state the bag's volume on the product page, so do not assume it replaces the quart bag. Everything else, such as a razor, toothbrush and solid items, wants a proper toiletry bag, which is covered in our dopp kit comparison. If you are building a full carry-on setup, our packing cube and carry-on luggage comparisons cover the rest.
