It’s an insulated stainless steel bottle with a plastic cap, and it kept water cool for our entire 17-hour temperature test. It didn’t leak in any of our tests, keeping your bag and all of its contents dry. The mouth is wide enough to add ice cubes, but narrow enough to sip without sloshing, especially if you’re on the move. And it can adapt to many situations, including the car (it fits in a cupholder) or the gym ( or ).
Our pick comes with the flex cap, a twist-off lid with a flexible carry handle. Color options: black, blueberry, cobalt, flamingo, graphite, kiwi, lava, lemon, mango, mint, olive, pacific, plum, raspberry, sage, stainless, white Size options:, and ounces Lids available:, (included) Dishwasher safe: no. If you would like a bottle with a lid that’s easier to drink from while moving, one that may fully close more reliably than a sport cap, you might want a spout lid.
The best bottle-and-spout combination we’ve found is on the. This is a double-walled, stainless steel bottle with a plastic lid that screws off to reveal a wide mouth opening that’s easy to add ice, fruit, or supplements through. We preferred this design wholeheartedly to the rubberized sport caps on other bottles. Those don’t account for human error—they’re too easy to accidentally leave half-open.
With the Takeya, you know it’s closed. It’s designed with gym goers in mind, but even if you wouldn’t be caught dead in a gym, the cap makes itself useful any time you may be drinking on the go. Color options: arctic, fire, fuchsia, lime, midnight, onyx, sapphire, slate, solar, teal, violet, red, white. Size options:, and ounces Lids available: spout (included) Dishwasher safe: lid, yes; body, no. If you occasionally want to carry a smoothie you’ve made at home, or if you’re looking for a water bottle that’s easily refillable from any source, get the. Though it seems nearly identical to the 21-ounce Hydro Flask Standard Mouth, its wide mouth has fundamentally different benefits: it can be filled from a blender or a soda fountain with a smoothie, fresh juice, or fountain drink, whether by you at home or by the employee across the counter at a cafe.
Refilling a standard mouth from any source other than a faucet isn’t so easy. (For hot drinks, we recommend looking into a ) In addition, this is the only wide-mouth bottle we looked at that has a straw cap available. If you opt for a straw cap, you never have to twist anything off to sip again, which makes this bottle nearly spill proof.
Color options: black, citron, cobalt, forest, graphite, lemon, mango, sage, stainless, tangelo, blueberry, flamingo, kiwi, lava, mint, olive, pacific, plum, white, raspberry Size options:, and ounces Lids available:, Dishwasher safe: no. This is only one of two true “bottles” we picked, which are defined by their narrow, tapered openings. That design can be limiting—only skinny ice will fit—but the is simple and enjoyable to drink from.
Why else would this be the design of choice for disposable plastic bottles? It strikes a sleeker profile than other options and comes in dozens of colors, patterns, and textures. Basically, it’s fun. This insulated stainless bottle worked as well as any of our top picks to keep the water inside cold. The Simple Modern performed identically to a S’well in our test, but costs half as much.
Color options: blush, bubblegum, Carrara marble, cumulus, deep ocean, glacier, glacier rain, glimmering gold, lavender swirl, midnight black, mint, oasis, ocean quarts, Pacific, Pacific dream, paradise, primrose marble, purple amethyst, rain aqua, reflection, robin’s egg, rock candy, rose gold, royal raspberry, Sahara, sandstone, sea shell, simple stainless, slate, sorbet, starry night, strawberry, sunset, sweet taffy, tropical seas, tuxedo, watermelon, winter white, wood grain Size options:, and ounces Lids available: twist cap (included) Dishwasher safe: no specification. Glass bottles aren’t as durable as other options; they can be heavy, and are poor insulators. But they don’t transfer any taste from bottle to water, and drinking from glass is really pleasant. Our favorite glass bottle is the. It’s made of borosilicate glass, comes with a silicone sleeve for drop protection, and at no point does your water come in contact with plastic—the cap is lined on the underside with stainless steel. Based on our research, but we recognize that some people just don’t want plastic touching their stuff.
This is one of the few bottles we’ve found that has a metal-lined cap rather than some form of plastic. Color options: jet black, aqua blue, baby blue, glow in the dark, lavender, pastel green, misty rose, pastel grey Size options:, and ounces Lids available: stainless steel lined lid (included) Dishwasher safe: yes. If you’re traveling and want a collapsible bottle, the is our favorite. At first we weren’t sure what to make of this former Kickstarter design, but it proved itself in testing. It easily collapses while still being sturdy enough to hold—no bag-like flopping or bending. It was leakproof and easy to fill, and it folds to less than 1 inch in height.
However, if you hate the taste of plastic, sorry, this is 100 percent silicone, which can, including that of plastic from the manufacturing process. In addition, the capacity isn’t quite as advertised: Our Hydaway held only 18 ounces of water, to the brim. Color options: chili, fire, midnight, snow, storm blue, tangerine Size options: and ounces Lids available: screw-off sip lid (included) Dishwasher safe: yes. Though it’s not as durable as metal, and won’t keep your water cold like an insulated bottle, the is super affordable, has been a pick in this guide since it was first published in 2014, and is still here. It’s a plastic bottle with a plastic, flip-top lid and spout.
It has passed years of leak tests, and has a push-button top, so if you have limited hand strength or mobility issues you can still use it, and if you don’t want to twist anything, it’s a great option. The lid has a lock, so it’ll stay closed in your bag, and the lid also has a ring that you can turn to track your water intake for the day (if that’s your thing). Colors available: dark blue, green, magenta, purple, red, smoke, teal Sizes available: 24 ounces Lids available: flip top (included) Dishwasher safe: yes. Water bottles didn’t used to be so complicated. Water fountains were plentiful, no one knew or cared about BPA, and anyway, there was only one bottle around that didn’t leak: the original. Now, a water bottle is a fact of life, as integral to everyday carry as your keys, phone, and wallet. Though it’s easy to long for simpler times, we’re not convinced that the ubiquity of reusable bottles is a bad thing.
A reusable water bottle is better for the environment, and more cost effective than buying pre-bottled water. According to a study published in the journal (PDF), bottled water production in the US alone in 2007 required somewhere between 32 million and 54 million barrels of oil. That’s roughly 2,000 times as much as the energy cost of producing tap water. Since then, bottled water sales in the US have grown from 33 billion liters to surpassing sodas and soft drinks. For shoppers, bottled water is also a thousand times more expensive than tap water. Add the fact that in 2009 nearly half of all bottled water sold in the United States was nothing more than (PDF), it becomes difficult to argue with the value of a well-made reusable water bottle.
A reusable water bottle is better for the environment and more cost effective than buying pre-bottled water. We talked to urban planner Josselyn Ivanov, who wrote her for MIT’s Department of Urban Studies and Planning on the decline of publicly available water, aka drinking fountains.
“In the absence of investment and maintenance in drinking fountains, many people fill the void by hauling around their own personalized infrastructure,” she tells us. She pointed us toward a sign of the ultimate decline of public water:, a subscription service for water bottle refills in New York City, which will let you fill up your own water bottle inside a cafe where there is no water fountain—for a price.
And recently, the double-walled insulated water bottle has become de rigueur for commuters—and that makes sense. Insulated bottles keep liquid cold for hours, even in a car in the hot sun, and they’re less likely sweat on the outside, protecting anything sensitive they may be leaning against. They can also keep hot drinks hot, but they’re not designed to drink hot drinks out of. If that’s your main priority, you’d be better off with a. Finally, this guide focuses on bottles for adults, but we also have one for kids that features smaller (and more affordable) picks.
Picks for travel mugs and kids water bottles. Photo: Kyle Fitzgerald Well, it took only five years, but at this point there are very few water bottles we haven’t tested. Since 2014 we’ve looked at over 90 different bottles, weeded from the morass of online options, and performed leak and stress tests on all of them. As always, we start by looking at guides put together by trusted editorial sources such as,.
And every year, we listen to the opinions of Wirecutter’s readers—we had a number of great suggestions in the comments of the 2017 iteration of this guide. Any bottles we find online that show a pattern of owner complaints about build quality, usability, or leakage are dropped from the list of possible test candidates. We also eliminate bottles made by companies that appear to have a weak supply chain or no online presence outside of an Amazon listing.
If we recommend a product, we want to make sure that you won’t have a problem finding one to buy. And if the product is defective, you should be able to contact the manufacturer so that the company can make it right. We did not consider bottles made of aluminum, as it dents too easily, nor did we include bottles that have painted exteriors because the coating can chip and scratch easily, whereas powder-coated bottles like the Hydro Flask are far more resilient to wear. We also set aside bottles that are uncoated stainless steel; if you leave an uncoated stainless bottle in the sun, the exterior gets too hot to hold.
A subset of bottles, like the Klean Kanteen Wide Mouth, can easily be used as a water bottle, but because of the caps offered (travel mug caps) or the sizes available (limited to smaller sizes), they are more suited to hot drinks. In the case of the Klean Kanteen, both are true, and so we consider it a travel mug. If that’s what you’re looking for, we have a guide to. Finally, we set aside bottles that are available only in sizes larger than around 24 ounces (though several of our picks do come in much bigger sizes, including 32, 40, and 60 ounces). Once a bottle grows to a size that can hold a liter of water or more, it becomes cumbersome and heavy to carry, and doesn’t fit in backpack pockets or car cupholders. The larger sizes excel at water storage, like if you want a big jug to carry on a road trip or to sports practice, but are unwieldy for a daily commute.
How we tested. Bottles that failed our leak test, clockwise from top left: Klean Kanteen Classic with loop cap, Klean Kanteen Standard (insulated) with sport cap, Lifefactory 22oz with Flip Cap, and Healthy Human 21oz Wide Mouth Insulated. Photo: Eve O’Neill Our biggest discovery was how prone to user error sport caps can be. They make perfect sense on squeezable sport bottles, but the sport caps that come on the double-walled steel bottles are stiffer, making them easy to inadvertently leave open. I soaked an entire tote bag because of this.
In fact, sometimes we couldn’t tell if they were shut even if we used our hands, because of how the lid was designed. Temperature test For the past four years, we performed a temperature test, with a goal of seeing which bottle kept its contents coldest the longest.
Here are the results from 2017. In this test, each bottle was filled with water at 47 degrees Fahrenheit, and then every hour for 10 hours we took a temp measurement. What we’ve seen in years of testing is that every insulated bottle performs to within a few degrees of its competition. Brands love to make claims as to how long a bottle can keep something hot or cold, but basically you can buy any insulated bottle you want—they all work the same. This year we strove to illustrate the difference in internal temperature that could be expected between an insulated and uninsulated bottle. We filled each vessel with the same amount of water, around 54 degrees, and then took one temperature measurement exactly 17 hours later. Bottles with smaller bars were better at keeping water cold.
In this example, with only slightly chilled water and no ice, after 17 hours the water in the insulated bottles was still 10 degrees below room temperature, where every uninsulated bottle had warmed up to room temp. That’s sort of what it feels like standing in the shade compared with stepping into direct sun. You can buy any insulated bottle you want—they all work the same. There is a new feature being touted in bottle manufacturing: the use of a copper lining to keep contents even hotter or colder. It could work, and as Wesley Johnson, a cryogenics research engineer at NASA’s Glenn Research Center in Cleveland explains, “For spacecraft, we often use a similar technique for insulation.” The theory behind using copper in insulation (despite being an excellent conductor normally) is that heat is transferred through three forms: solid conduction, gaseous convection, and radiation, Johnson told us. A double-walled bottle already stops solid conduction, and a vacuum-insulated bottle will stop gaseous convection.
“This leaves only radiation heat transfer between the walls, which is a factor of approximately 10 less than solid conduction or convection,” said Johnson. And copper can be used to stop that last method of heat loss. But it works only under a set of specific circumstances. According to Johnson, “The main benefit of copper is that when it is polished, it is much more reflective of radiation heat transfer the copper liner needs to be: polished, installed in a vacuum, and done so in a manner that limits the amount of oxidation of the metal prior to pulling the vacuum.” We have tested bottles with and without copper linings, and so far we haven’t found any advantage to using copper.
The Yeti Rambler is “constructed with a copper plate to protect against UV,” according to its PR, and so are Otterbox tumblers, which we looked at for another guide. But neither Klean Kanteen nor Hydro Flask includes any copper in their designs.
Use test We took a hard look at bottle proportions. Sometimes as the capacity of a bottle increases, designers make them taller and skinnier—those are too easy to knock over.
Some designs are so large, they could be used as weapons. The 25-ounce could double as a small baseball bat. We also looked at the lip: If you’re drinking directly from the bottle, what’s that experience like? So too, we judged a bottle by the cap options it has available, and how versatile the bottle is.
Water Bottle Designing
Can the bottle fit in a cupholder? Can it hold hot liquid? There’s always someone who wants to put hot stuff in a water bottle, even when a would be a better choice and wouldn’t leave your water bottle eternally tainted with the taste of stale coffee. Our pick: Hydro Flask 21oz Standard Mouth. The is the most reliable water bottle we found.
It’s an insulated, double-walled stainless steel bottle with a powder-coated exterior (the permanent, lightly textured coating that’s responsible for all the color options now available) and a plastic cap. You can use it with two different lids: a flex cap (included) and a. We tested both, and neither leaked a drop, unlike the lids of Hydro Flask’s closest competitor, the.
Like the other double-walled bottles we tested, it kept water cooler than room temperature for the duration of our 17-hour test, and it didn’t sweat. In addition, the straight-from-the-bottle drinking experience was more comfortable than with any other steel bottle we tried, thanks to its well-tapered edge, and the standard mouth opening is the most versatile of all the styles we looked at because you can easily add ice cubes, but it’s not so big that water sloshes on your face if you’re not careful. If you want only one bottle, we think this is the one to get. This bottle can be used with two different caps, a flex cap (which we recommend getting) and a sport cap, neither of which leaked in testing.
We prefer the flex cap to the sport cap, as we realized in testing that sport caps aren’t very good at accounting for human error—the plastic is very stiff and difficult to close with your mouth, making it easy to leave them open halfway. Often, two hands are needed to make sure it’s pressed down fully, which negates the purpose of a sport cap.
If you want only one bottle, we think this is the one to get. However, if that doesn’t bother you, we prefer the Hydro Flask sport cap to the one we tested on the Klean Kanteen. It didn’t leak, not even through the tiny one-way valve that allows air to flow in through the top (though it is not advertised as leakproof, because of this airflow valve). The Klean Kanteen cap leaked through the air valve in two separate tests. In addition, the Hydro Flask valve sits flush with the inner plug when it’s closed, making it easier for you to tell that it’s fully shut.
The sport cap on the Klean Kanteen doesn’t close totally flush, making it difficult to figure out if it’s been closed the whole way. Like the other double-walled bottles we tested, but unlike single-walled ones, the Hydro Flask doesn’t sweat in normal use. That is, the insulation works both ways, so cold water inside the bottle won’t cause water vapor to condense on the outside of the bottle.
The tapered metal edge of the HydroFlask makes for a more pleasant drinking sensation than those of the other insulated bottles we tested. Photo: Kyle Fitzgerald If you opt to drink straight from the bottle, the Hydro Flask has a narrow, tapered metal edge that mimics a glass better than any other option, including the round lip on the Klean Kanteen, and the thick, industrial-feeling lip on the. The standard mouth opening is 1¾ inches wide—wide enough to fit ice, but not so wide that water will slosh around if you drink while moving. This bottle comes with a textured, lightweight powder-coat, which prevents the exterior from getting too hot to hold if it gets left in the sun, and is available in four sizes: 12, 18, 21, and 24 ounces. We think 21 ounces is the ideal capacity—big enough to keep refills to a minimum, but not as unwieldy as the 24-ouncer. The 24-ounce bottle is tall and narrow, possibly easy to tip over, and feels large.
The cap is BPA free, and Hydro Flask offers a on this product. That means if the cap leaks, if the bottle loses its insulation properties, or the product gets damaged in shipping, the company may replace it for you. Every type of water bottle has reports of leaks. Whether it wears out, breaks, or someone just gets a lemon, it’s a fact of life with this product, and every single bottle we recommend in this guide has had a report of a leak or a faulty cap at some point. With that in mind, the complaints against the Hydro Flask are infrequent and few. Not a single one of its bottles, in any style of cap, leaked or somehow failed to perform in our tests. Unlike aluminum bottles, they don’t dent as easily; unlike glass bottles, there are no issues with the bottoms cracking; and unlike plastic bottles, they don’t deteriorate quickly while in use.
Bottle comes with an included silicone bumper to prevent you from dinging your drink bottle on hard surfaces; To be nitpicky, it is recommended this bottle gets hand-washed, and the caps too. Heat from the dishwasher can damage insulated bottles, and discolor the powder-coat. In addition, if you choose to get the sport cap, it is not intended to be leakproof. In our tests, we didn’t get any liquid seeping through the air intake valve, but if you must have an absolute seal, don’t rely on this cap design. Color options: black, blueberry, cobalt, flamingo, graphite, kiwi, lava, lemon, mango, mint, olive, Pacific, plum, raspberry, sage, stainless, white Size options:, and ounces Lids available:, Dishwasher safe: no Also great: Takeya 24oz Actives.
If you want a bottle with a spout, our favorite is the. It’s an insulated, double-walled stainless steel bottle with an exterior powder coat, and a plastic lid.
The lid has an integrated carry handle, and because this bottle was designed with gym goers in mind, it comes with a silicone base, or boot, to prevent scraping on concrete floors. But it’s not as widely available as our main pick, the Hydro Flask. Unlike a traditional sport cap, the Takeya’s flip-cap drinking spout is 100 percent leakproof, water flows easily, and you can tell at a glance if it’s closed, so there’s no chance it’ll go into your gym bag half-open to leak all over your clothes. When opened, the flip cap can be firmly locked into position so that it doesn’t flap in your face while you drink, unlike the cap we found on the, which we struggled to seat in its designated holder. The Takeya’s flip-cap drinking spout is leakproof and easy to drink from, and the cap locks open so you don’t bonk yourself in the nose while drinking. Photo: Kyle Fitzgerald The whole apparatus twists off to reveal a 2¼-inch-wide mouth opening, easier to fit lemons or scoops of electrolytes into than the 1¾-inch-wide mouth of our top pick, another design choice that makes this bottle slightly tailored for the fitness crowd.
The Takeya comes in five sizes: 18, 24, 32, 40, and 64 ounces. We tested, and recommend, the 24-ounce bottle, because as with the other bottles, 32 ounces starts to feel too big for a commute. Go for the larger bottles if keeping this bottle in the car, taking it to sports practice, or using it for a major workout. The lid is listed BPA free on Takeya’s website.
The lid is dishwasher safe (top rack), but hand-washing is recommended for the body, and Takeya offers a (but you’ll need a receipt). Flaws but not dealbreakers The downside of substituting a spout for a traditional sport-cap design is that you have to use two hands to screw the lid on (one to hold the bottle, one to close the lid). But if you really need to be able to open and close a bottle one-handed, or with your mouth, a traditional is probably your best option anyway, as the hard rubber sport caps on double-walled bottles are very stiff. Color options: arctic, fire, fuchsia, lime, midnight, onyx, sapphire, slate, solar, teal, violet, red, white. Size options:, and ounces Lids available: spout lid (included) Dishwasher safe: lid, yes; body, no Also great: Hydro Flask 18oz Wide Mouth.
The is a wide-mouthed version of our main pick. Drinking directly from the wide mouth makes you a bit more prone to spills and sloshes than drinking from the standard mouth, and this bottle isn’t available with a sport cap, but the wide mouth is the best choice if you want to carry smoothies or juices. The Wide Mouth is easier to fill from a blender or bottle than a standard-mouth bottle.
It’s also the best design if you’re looking for a bottle to use instead of disposable cups. When I’m working, I buy about three different drinks a day, whether soda from a fountain, kombucha on tap, fresh juice, iced tea, or anything else.
It’s a nauseating feeling seeing all of those cups piling up; this is the bottle I turned to to eliminate that waste. The wide mouth also makes it easy to clean, so you can get out gunked-up pieces of that kale smoothie more easily. Additionally, this is the only wide-mouth bottle widely available with a straw cap. The Klean Kanteen wide-mouth bottle doesn’t have this option, and a straw cap does specific things no other cap can do.
It’s the best for using while driving, because you don’t have to tip a bottle back or precariously police an open lid. A straw cap is a good option if you’re worried about spills, and also for slurping up all that smoothie you’re carrying around. Finally, if you have deep concerns about how cold your water is staying, the best way to keep it cold over a period of time is to not take off the lid. A straw cap is one of the few options, other than a sport lid, that can stay sealed while you drink from it. The Wide Mouth HydroFlask is easier to fill from jugs and pitchers than the narrower Standard Mouth of our top pick. Video: Kyle Fitzgerald The Hydro Flask comes in four sizes: 18, 32, 40, and 64 ounces. Like the Takeya pick, the big sizes are great for major hydration needs, but impractical for everyday carry because they can be hard to grip one-handed and extremely heavy when filled.
For that reason we like the 18-ounce size for a commuter. The same no-dishwashing rules apply to this as to our top pick: both the lid and bottle should be hand-washed. The cap is BPA free. Hydro Flask offers a on this product. Flaws but not dealbreakers It didn’t leak in our tests, but treat the straw cap like a sport cap. It has a valve that has to let air in, so leaks are possible.
Color options: black, citron, cobalt, forest, graphite, lemon, mango, sage, stainless, tangelo, blueberry, flamingo, kiwi, lava, mint, olive, Pacific, plum, white, raspberry Size options:, and ounces Lids available:, Dishwasher safe: no Also great: Simple Modern 17oz Wave. Tapered bottles are really nice to sip from, and of all of the styles, these are the bottles that come in a million fun colors, patterns, and textures. They’re a more elegant shape than the weighty cylinders of the other bottles we recommend, and they’re the only bottles that are actually shaped like, well, a bottle. If you want a tapered bottle, our pick is the. It’s not as versatile as bottles with wider mouths, but because it is an insulated bottle, it will still keep your water insulated from outside temperatures, and the exterior won’t sweat. It’s made of double-walled stainless steel, and performed identically to the more well-known, near-identical in our testing, with no leaks and excellent temperature retention. It is likewise available in a wide variety of colors and patterns and costs almost half as much.
The Simple Modern bottle looks and performs as well as a S’Well but costs half as much. Photo: Kyle Fitzgerald The Simple Modern and S’well have only a single cap option: a stainless steel screw top lined with plastic.
In our temperature test, the Simple Modern kept its interior two degrees colder than the S’well—not a significant difference, but significantly better than we’d hoped from a bottle that’s half the price. The Wave comes in four different sizes: 9, 17, 25, and 34 ounces. We tested the 25-ounce bottle, and found it too large for everyday use. For that reason, we recommend getting the 17-ounce size, even though we haven’t tested it.
The base of the 17-ounce bottle fits in a cupholder, and the mouth is 1⅜ inches wide. It’s available in a rainbow of colors, from matte powder-coats to glittery metallics. On the company’s website the bottle is listed as BPA free. Flaws but not dealbreakers As we mention above, this type of bottle has a very narrow neck, so you can’t fit normal-size ice into it, and if you throw in a lemon wedge, you might never get it out again. No information is given as to if you can wash this bottle in the dishwasher, but judging from what we know from how heat affects the insulation (and discolors powder coats) on other models, it’s probably safe to assume that this needs to be hand-washed—which can be tricky due to its narrow neck. Simple Modern offers only a 90-day warranty on manufacturer defects. Glass bottles aren’t particularly utilitarian—they’re simply not as durable as their metal counterparts, they tend to be heavy, and they don’t insulate liquids.
But pure utility aside, drinking out of glass is enjoyable. The bottle doesn’t transfer any taste to your water, and sipping from glass just feels nice. Of all of the options, we found that the provides the best experience. It has a small mouth that’s more pleasing to drink out of than wide-mouth glass bottles, a cap that is unique among all of our picks in its simplicity, and it’s made of borosilicate glass.
Borosilicate handles thermal shock better than common soda lime, making it slightly more durable than average glass. A wide-mouth bottle, like our former glass pick, the, can feel a lot like drinking out of a jar. Which is why we considered glass bottles with narrow, tapered mouths instead, in spite of the fact that the opening is too narrow for standard ice cubes. Because a glass bottle doesn’t keep water cold anyway, we decided that wasn’t a problem. The Purifyou’s cap is lined in stainless steel; your water never touches plastic.
Photo: Kyle Fitzgerald The cap is unique among those of the bottles we looked at—it’s the only lid we found that’s lined with stainless steel., but if you don’t want any plastic touching your water, maybe for taste reasons, this is the bottle to get. The cap is easier to twist on and off than any other cap on this list, and unlike the cap on the similar bottle, is uncomplicated. It doesn’t have many moving parts to get gunked or moldy, a flavor that’s especially noticeable with glass because there’s no transferred flavors from other materials—like you can get from the metal and plastic in other bottle types—to mask it.
The Purifyou doesn’t come with any additional cap options, but when we tested the optional lids on the competition from Lifefactory, they leaked. The Purifyou is also the only borosilicate glass bottle we looked at. Again, borosilicate glass resists thermal shock. That means that if you take the bottle out of a hot dishwasher and fill it with cold or room-temperature water, it will resist shattering better than bottles made of common soda lime glass. And yes(!), this bottle is dishwasher safe, on the top rack. This bottle comes in three sizes: 12, 22, and 32 ounces.
We tested and liked the dimensions of the 22-ounce bottle. Its base does fit in larger cupholders (it’s 3¼ inches wide). The mouth is 1⅛ inches wide, too small to add much of anything. In addition, the center body is a little wide, and not tapered like some others, though we had no problem holding it. If you’re looking to glass for an environmentally friendly option, unfortunately this bottle won’t help, because the silicone sleeve is not recyclable, nor is the cap, because it’s made of two materials fused into one. If you have environmental concerns, the best thing to do is to buy the bottle you know you will use the most, and use it. Purifyou offers warranty coverage of all manufacturer’s defects, and “3 months of free product insurance”.
Flaws but not dealbreakers Glass bottles are extremely limiting. They excel at carrying room-temperature water, and that’s it.
They don’t have any insulative properties, so they won’t keep water hot or cold. They’re the heaviest of all of the options, and though most are quite sturdy, they are still glass, and every now and then they crack.
Color options: jet black, aqua blue, baby blue, glow in the dark, lavender, pastel green, misty rose, pastel grey Size options:, and ounces Lids available: stainless steel lined lid (included) Dishwasher safe: yes Also great: Hydaway 21oz. The Hydaway is an all-silicone bottle with screw-off cap, and a sip lid. It does an excellent job of finding the middle ground between collapsibility and leak prevention. Our former pick, the Nomader, is a sturdy bottle—almost like the real thing—but it collapses to not even half its height, about 6 inches.
On the other hand, completely flat bottles we’ve looked at, like the, can leak when lateral torsion is applied. The Hydaway manages to scrunch down small, and it passed all our leak tests. The design is also an upgrade over bag models. The center ring of the bottle is rigid, so the bottle doesn’t compress or move at all while you take a sip, so you can drink out of it like you would a normal bottle. The Hydaway feels vaguely ridiculous to drink from, but it’s miles better than drinking from a floppy plastic bag, like most other collapsible bottles tend to be. Photo: Kyle Fitzgerald It comes in two sizes, 12 and 21 ounces. We tested the 21-ounce bottle and think it’s the right size for travel (though it doesn’t actually hold 21 ounces, only 18).
The mouth is 1⅞ inches wide and is easy to fill from fountains or faucets. The Hydaway is dishwasher safe. Qq1****8511 office for mac. Hydaway has a on its products, though it doesn’t cover drops or normal wear and tear, which seems like it’d be the most common point of failure on an accordioning bottle. Flaws but not dealbreakers The advertising for this bottle is misleading. First, it made water taste like plastic. The taste dissipated over time, but never fully, and that’s a far cry from “taste and odor free,” as mentioned online.
Additionally, this bottle holds only 18 ounces, to the brim, regardless of the 21-ounce claims on the package. If either of those are a turn-off, the, our former pick, has neither of those problems (it just doesn’t fold down very small).
Our other concern is that we haven’t tested the Hydaway over the long term, and collapsible bottles, due to their nature, show wear and tear quickly. But for now, it’s given us no cause to worry and we’ll keep testing and report on how it holds up over time. Color options: chili, fire, midnight, snow, storm blue, tangerine Size options: and ounces Lids available: screw-off sip lid (included) Dishwasher safe: yes Budget pick: Thermos 24oz Hydration Bottle with Rotating Intake Meter. The has been our favorite plastic water bottle for the past four years. It’s an affordable plastic bottle with a flip-top spout lid that is leakproof, feature-laden, and more pleasant to use than the 19 other plastic bottles we’ve tested it against. Also, thanks to its flip top, it’s easy to open if you have limited mobility or grip strength. If you’re worried about the safety of drinking water out of plastic bottles, don’t be., and that plastic—even plastic with BPA—is just fine to drink out of.

Even so, the Thermos 24oz is made from BPA-free plastic. You can easily open the Thermos 24oz with just one hand, and without much force. Video: Kyle Fitzgerald It’s been leakproof in every test we’ve run for four years, and the flip lid is equipped with a durable and easy-to-use locking clip. It’s also spring-loaded, so the cap will stay out of your face, the signature difference between this bottle and the nearly identical. Compared with the similarly modeled, we liked the thicker metal on the Thermos’s lock. Finally, the lid has a metered dial that you can use to track how many refills you’ve gone through in a day—sure, it’s a goofy concept, but if you’re into that sort of thing, the feature is well-implemented. Flaws but not dealbreakers After three years of near-constant use, we don’t have a lot of criticism to throw at the Thermos 24oz.
Perhaps the only request we could make of Thermos would be for the company to sell it in a few different sizes. Colors available: dark blue, green, magenta, purple, red, smoke, teal Sizes available: 24 ounces Lids available: flip top (included) Dishwasher safe: yes. Photo: Kyle Fitzgerald For the past several years, the has been our top pick. This year, it was unseated by Hydro Flask, due to the fact that all the Klean Kanteen caps we tested leaked.
We performed the test twice: The sport cap leaked through the threads, both times, on both bottles. The loop cap leaked only the first time, though the second time we cranked the cap on so tight, we could barely get it off. The problem is that the Hydro Flasks didn’t leak at all, not any cap, not any test.
They performed without a single compromise. Several of our editors and staffers have had our Klean Kanteen picks for many years, and have not had leaking problems, so we are not sure why our test bottles performed the way they did. Yet Klean Kanteen hardly has a spotless record. The was our pick in 2016, when it was neck-and-neck with the. In 2017, we noticed that both bottles leaked when put on their side overnight.
Our previous pick was also only single-walled stainless steel, which doesn’t insulate as well as either the Hydro Flask pick or double-walled Klean Kanteens we tested this year, and also formed far more condensation, and had a less durable color-coating. We believe that if you buy or have bought a Klean Kanteen in the past, it likely performed well and as expected. The problem is that the Hydro Flasks didn’t leak at all, not any cap, not any test. They performed without a single compromise.
The small, one-way valve on the Hydro Flask sport cap, which isn’t even advertised as leakproof, also didn’t spill a drop; the Klean Kanteen did lose liquid through this valve. So with that in mind, it didn’t seem necessary to force an argument to keep our long-standing top pick, especially because of the long history we’ve had of leaks popping up occasionally with the Klean Kanteen products. We’ll test them all again before too long, and in the meantime, we’re going to recommend the Hydro Flask as the best option. The competition.
