Over our years of travel, we've learned that staying hydrated can be crucial to a successful day of exploring. Dealing with headaches and other ailments because you’ve forgotten to sip along the way is not how we like to start a trip.

Finding the best travel water bottle for you can be intimidating—and expensive. What happens when your travel daypack doesn’t have a water bottle pocket? Or you don’t want to load down your travel backpack with one more bulky item?

We’ve done the homework for you to create this list of travel water bottles that quench your thirst, no matter the situation or location. Our team has tested almost all of the bottles on this list, and some even have full written reviews you can turn to for more details.

So grab a beverage, and let’s dive in. Cheers!

1. memobottle A6 (with Silicone Sleeve)

Best for: Professional Travelers

MemoBottle A6 Review

Why We Like It: Its rectangular design fits inside packs without a dedicated water bottle pocket.

One constant in the hundreds of bags we’ve tested over the years here at Pack Hacker is that there’s no consistency in the pockets provided in a travel backpack. While we may wish for a water bottle pocket to be standard, it’s not always the case. Memobottle solves that problem by designing their travel water bottles to fit inside the pocket or sleeve of any bag like a notebook. They’re modeled after international paper sizes so they can slip into the thin pocket of a laptop bag just like a file folder. We know it looks like a flask, but that shape makes it a great solution when a bag manufacturer forgets that drinking isn’t just for Old Fashioneds at Happy Hour. The A6 holds 12.7 ounces of liquid, and we’ve found it an innovative solution to make the most of every inch of space in our sling or small bag. Adding the silicone sleeve to the lightweight plastic bottle provides some insulation, or you can opt for the leather sleeve for a more stylish look. Without the sleeve, it’s a clear water bottle, so you can see when it needs to be cleaned. The memobottle is available in various sizes: the larger A5, smaller A7, and The Slim, which is skinny and tall like regular water bottles. Whichever you choose, it offers a unique, minimalist style that fits just about anywhere.

2. Chilly's Series 2 Water Bottle
Chillys Series 2 Water Bottle Review

Why We Like It: There are a ton of different colorways to choose from, so you can select a style that’s as vibrant as you are.

If you wear your style on your sleeve, why shouldn’t you show it off with your water bottles? Chilly's has the widest variety of colors and patterns available of any brand on this list. The Chilly’s Series 2 Water Bottle has an updated style and new features like an antimicrobial collar, carry handle, and a rubber bottom that muffles the sound when you set the bottle down. While the Chilly’s Original still has the most options for colors and patterns, we think the updated features are a good reason to go with the upgrade. Plus, Chilly’s continues to add more colorways, prints, ombres, and special collections to the Series 2 line. Art from the Tate Modern, anyone? No matter the version, Chilly's water bottles have a carry handle reminiscent of a Hydro Flask, although it’s a bit shorter, reducing the clearance between your fingers and the top of the cap. It’s still comfortable to carry, but worth noting for those with larger hands. While we noticed the rubber bottom is beginning to peel off ours, it’s a small blemish on an otherwise sleek bottle. Plus, your tastes will likely change before that happens, so you can always grab a new one to match your current style. This makes the Chilly's Original the best insulated water bottle for those who want variety and options in terms of styling and aesthetic. No matter which one you're sporting, rest assured you'll never confuse it with your friend's or a fellow traveler's—unless you both choose the same pattern, of course.

3. Hydro Flask 18 oz Standard Mouth Water Bottle
Hydro Flask 18 oz Standard Mouth Water Bottle Review

Why We Like It: It’s a reliable bottle from a brand we’ve come to know and trust—and it keeps your drink cold all day long.

If you need the best insulated water bottle, Hydro Flask's wide selection is a good place to start looking. Their bottles are well-insulated, comfortable to carry, and available in several bright and neutral colors, depending on your tastes. Hydro Flask also offers a larger variety of capacities compared to some other brands. On top of that, the different sizes have a similar footprint, so you don't have to worry about them fitting in a cup or bottle holder. For example, the 18 and 21-ounce bottles are just less than an inch apart in height and have the same circumference. That means you have more flexibility when choosing what travel water bottle is best for which occasion without losing the ability to use your water bottle pocket. It's not just for water and other cold drinks, either—Hydro Flask is also great at keeping hot drinks hot, and we like to use it for our coffee. If you're looking for a way to soften the clunking sound when you set it down, Hydro Flask sells an accessory called the Flex Boot to mute the clanging. And we'd be remiss if we failed to mention the potential for denting, though we haven't experienced that with our bottles yet—and we have tested quite a few. Sometimes there's a reason something is a classic, which is the case with Hydro Flask.

4. Klean Kanteen Insulated TKWide 16 oz
Klean Kanteen Insulated TKWide 16 oz Drinking Straw

Why We Like It: The Twist Cap comes with an included straw that hides away when you fully close the lid, so it travels without spilling.

Can we let you in on a secret? The Klean Kanteen TKWide 16-ounce bottle looks like standard wide-mouth water bottles, but it's tailor-made for those who love to sip through a straw. The lid looks similar to other flat-tops with a handle, but when you twist the top layer, out pops a silicone tip. Presto! You can enjoy your water without worrying about spilling down your chin. If having a straw is essential for you, this might be the best insulated water bottle for you. While we've had problems with other straw bottles leaking, the TKWide's straw forms a good seal when closed. Of course, using a straw travel water bottle means you have to pack a brush to clean it, but that's a small price to pay if it's what you prefer. And if it’s not, Klean Kanteen offers different cap types, so you can mix and match if you're not digging it one day. You can take the cap completely apart to get it squeaky-clean, and it's connected to a stainless-steel straw that pops out without a hassle, too. Don't try to drink coffee out of this one, though—we don't have to Google third-degree mouth burns to know we don't want them.

5. Avana Ashbury
Avana Ashbury Review

Why We Like It: You can use the mouthpiece to sip or like a straw—you don’t have to choose until it’s at your lips!

If you're a Libra and have trouble making up your mind (and some of us on the Pack Hacker team can certainly relate!), opting for the Avana Ashbury Water Bottle means you don't have to pick whether you want to use a straw or not until you actually go to take a sip. Its double lid includes a straw and a spout under the cap—bonus! That versatility may be enough for some to consider this the best insulated water bottle for them. That said, There's a little learning curve, but it makes for easy sipping once you master it. The Ashbury cap is separate trom the bottle, so you’ll have to hold it when you want a drink, but that’s an issue with many brands. We think it's a small price for the extra versatility with the Ashbury. The slim bottle fits comfortably in your hand and can squeeze into skinnier water bottle pockets. It has a flexible carry handle on the lid, but be sure to hold on tight, as we have found this travel water bottle can dent if you drop it. Avana offers a variety of neutral colorways in matte and metallic options, so there's bound to be a choice that suits your style. Pick one and enjoy your grown-up sippy cup whenever you're thirsty.

6. Vapur Eclipse Water Bottle

Best for: Full-time Travelers

Vapur Eclipse Water Bottle Review

Why We Like It: It folds up small enough to fit in your pocket when you aren’t using it so that you can save space and weight.

Minimalist, stop here: these are the travel water bottles for you. The Vapur Eclipse Water Bottle is the most packable on this list, even with a large capacity up to 1L. Vapur includes a carabiner clip for two reasons: to attach it to the outside of your pack and to secure the rolled-up bottle when it's packed away. Its collapsibility means you're not stuck lugging around an empty travel water bottle when you're done with your drink—simply slip it into your daypack until you're ready to refill. It’s a great travel water bottle when you're packing light because you only need to carry what you want to consume. In fact, our founder, Tom, carried this bottle alone when he traveled the world for two years as a digital nomad. That's not to say it's perfect. We can't slide it into a bottle pocket, even when it's filled to the brim, so you need to clip it on your bag every time. It also lacks insulation, which can be a disadvantage in hot climates. We think those are minor drawbacks, though, compared with the convenience of this bottle.

7. Nomader Collapsible Water Bottle
Nomader Collapsible Bottle Review

Why We Like It: It’s a packable bottle with a little more structure than a folding bottle for those who like something to hold onto tightly.

If you like packable water bottles but are looking for a little more structure, give the Nomader Collapsible Water Bottle a try. It strikes the sweet spot between rigid and collapsible water bottles. It looks like a standard bottle, but the silicone construction rolls into a neat little package. Grab the strap when your hands are full; it's a helpful feature so you can carry your takeout and your water, too. We have to note that its lid and cap are bulky, reducing its packability. You may not be able to squeeze this one everywhere, but it fits in many slings and bags. Like most collapsible water bottles, it also lacks insulation: in most cases, you're sacrificing that feature for packability. It’s structured shape makes it easier to drink from than some other collapsible bottles, because it holds its form in the center. With its flexible qualities and other perks, you may decide the Nomader is the travel water bottle for you, no matter what.

8. Zojirushi Cool Bottle (SD-CS50)
Zojirushi Cool Bottle Review

Why We Like It: Most of the time, you get lightweight or insulated—but this bottle gives you the best of both worlds.

For the best of both worlds—light weight and insulation—try the Zojirushi Cool Bottle. It's a good fit for ultralight packers who don't like drinking out of collapsible bottles. At only 9.3 ounces, it's one of the lightest insulated bottles we've found. Compared to other insulated water bottles from brands like YETI that can weigh in at more than a pound, the Zojirushi delivers. We dig the secure opening mechanism—no one wants to worry about the cap popping open and releasing the Kraken into your bag, and we don't stress with this travel water bottle. The spring-loaded straw is perfect for those who like to sip instead of chug. It comes apart so you can thoroughly clean it, although the flexible nature of the straw means a straw cleaner comes in handy here. We also have to note that there are several small parts to keep track of, so we wouldn't try cleaning this in a tiny airplane bathroom. If you’re looking for something that will keep your drink cool without breaking a sweat, this might be the best insulated water bottle for you.

9. EcoVessel The ASPEN Insulated Water & Wine Bottle
Ecovessel Aspen Review

Why We Like It: It can be used as a water bottle or a wine container for ultimate drink variety.

It's five-o-clock somewhere, and you can have your water (and wine too!) with the EcoVessel The ASPEN Insulated Stainless Steel Water & Wine Bottle. With a style that could complement a bartender's cocktail shaker, we think this is a water bottle James Bond might ask for if he ever opted to hydrate before his martini. EcoVessel touts its suitability for cocktails, wine, and non-alcoholic hot and cold beverages, so we don't think this is a coincidence. The high-quality insulation is supposed to keep beverages cold for days: we tested this and found a drink only lost about 10 degrees after 12 hours at nearly 70 degrees. That's because the stainless steel bottle is triple-insulated, and the lid is insulated too. Also good to note is the lid's design: your water never touches plastic, which some users appreciate. The ASPEN is significantly more compact than other insulated bottles we've mentioned thus far, so it's the best insulated water bottle for sliding into smaller bags. Fill it with cold water for your travels, then refill it for Happy Hour when you reach your destination.

10. GRAYL Ultralight Water Purifier
GRAYL Ultralight Water Purifier

Why We Like It: There’s a water filter inside to ensure the water you’re drinking will keep you hydrated and healthy.

The GRAYL Ultralight Water Purifier is a travel water bottle more at home in the woods than the airport. GRAYL's filtering system eliminates harmful bacteria and heavy metals in seconds, allowing you to drink from any fountain, river, or other water source you stumble upon. We, and other world travelers, know that even densely populated areas aren't guaranteed to have potable water, so wherever you roam, this bottle puts your strength to use to provide you hydration. Fill the outer refill with water, insert the inner press filter and bottle, and press down. In just over 15 seconds, the water travels through the filter at the base to create safe drinking water when you need it most. The filter lasts for up to 300 uses. Paying attention to how long it takes to press the water cues you in as to when the filter needs replacing so you don’t have to keep track; when it creeps up to 25 seconds, you'll want to consider putting in a new cartridge.

11. Purist Collective Mover 18oz Bottle

Best for: Relaxed Travelers

Purist Collective Mover 18 OZ Bottle Review

Why We Like It: It has a thin layer of glass on the interior to ensure your water doesn’t take on a stainless steel taste over time.

Supertasters, this is the travel water bottle for you. The Purist Collective Mover preserves the taste of water, no matter what else you fill it with throughout the day (or night). Like many other bottles, Purist Collective uses stainless steel as its base, but it also has a 60-nanometer layer of unbreakable glass inside—that's what touches your drink. Are you tired of tasting metal when you leave your travel water bottle sitting too long? You won't have that problem with the Purist Collective Mover. It’s great when you don’t want to chug your drink while traveling, and would prefer not to taste the flavor of yesterday afternoon's lemonade. This bottle can handle hot and cold liquids, so you can pack just one vessel for your road trip for both your morning coffee and afternoon hydration. It’s only rated up to 185 degrees (our coffee pot perks at about 170) so beware of pouring boiling water straight from the kettle. You wouldn’t want to scald your mouth like that anyway! If you’re searching for a bottle that can handle both hot and cold beverages, this may be the best insulated water bottle for you.

12. Nalgene Wide-Mouth Water Bottle 32oz

Best for: Frugal Travelers

Nalgene Wide-Mouth Water Bottle 32oz Review

Why We Like It: It has a large capacity and measurements printed on the side, so you know exactly how much water you’ve consumed each day.

We know we’re supposed to drink more than a dozen cups of water daily, but it can be hard to keep track of your hydration. The Nalgene Wide Mouth travel water bottle takes the guesswork out with the water level printed along the side in both imperial and metric measurements. If you’re someone who doesn’t like the metallic taste of stainless steel water bottles, it's made of BPA-free copolyester to resist stains and odors. The material is durable enough to take a fall from a bag while bike riding and come out without a dent, too (not that it’s ever happened to us, of course…). The attached loop helps you keep a handle on the bottle so that, hopefully, that won’t happen to you. It's light for its size, too—the 32-ounce bottle weighs in at just 6.25 ounces, so it doesn't add much weight to your travel backpack. Choose from more than 20 colors, and know you’ll have no problem filling the wide-mouth opening with ice, a water filter, or a water purifier. It's easy to get your hand in for cleaning, too, and it’s a clear water bottle so you can see when it needs to be washed. This isn’t the best insulated water bottle out there, but what you miss in insulation, you make up for in capacity. It’s made in the USA and guaranteed for life, so this may be the last travel water bottle you need to buy.

13. CamelBak MultiBev 17 oz Bottle / 12 oz cup
CamelBak MultiBev 17 oz Bottle / 12 oz cup Review

Why We Like It: It’s a bottle and a cup in one, so you can share your drink with a friend or partner who comes along for the ride (or hike).

Are you the type to share a drink after a long day's trek? Then the CamelBak MultiBev may be the best insulated water bottle for you. The bottom of this two-in-one container unscrews to reveal a removable travel cup. Fill it with coffee so you and your favorite person can enjoy a mountain sunrise, or split some cocktails at the beach with a friend. Stored inside the bottle’s cap is a silicone lid for the cup we use to sip without spills. Fold it up for easier storage, or leave it at home and stash snacks or a tea bag in the cap instead. When heading out to explore a new city, screw the cup back on to seamlessly transition the CamelBak MultiBev to more typical travel water bottles. It's insulated, too, so you can fill it with a drink hours before you plan to stop for a sip and still have it be the temperature you prefer.

14. O2COOL Mist ‘N Sip Misting Water Bottle
O2COOL Mist 'N Sip Misting Water Bottle Review

Why We Like It: The top of the bottle doubles as mister, so you can refresh yourself during the warmest parts of the day without wasting much water.

Theme parks are a fun travel destination, but spending hours wilting while standing in a hot line can take the amusement out of amusement park faster than you can say, "I'm melting!" The built-in trigger mister on the O2COOL Double Wall Mist 'N Sip travel water bottle will keep you cool wherever you roam, whether it's "Walley World" or the Grand Canyon. Just don't use the Mist 'N Sip function if you're drinking lemonade! No one wants a face full of sugar water. Whatever beverage you enjoy, the double-wall insulation keeps it cold throughout the day while still being flexible enough to squeeze a drink into your mouth. The pull-top spout includes a silicone cap to prevent leaks and keep out dirt. We want to warn you that the two-in-one functionality makes the lid heavy, so the bottle can tip when empty. The lid takes some care to clean, too, but we think the chance to have your drink and personal coolant at the same time makes this the best insulated water bottle for the active traveler.

15. Stanley IceFlow Flip Straw Jug
Stanley IceFlow Flip Straw Jug Review

Why We Like It: This thing is humongous—enabling you to stay hydrated at the beach or when your AC is out.

Do you plan to spend the day at the beach, the pool, or the park on your next trip? Put this big jug on your packing list! While we probably wouldn't carry the Stanley IceFlow Flip Straw on a 10-hour hike, it's the best insulated water bottle when we plan to pop a squat for a long time. It has double-walled insulation to keep your drink cold for hours so that you can boost your hydration throughout the day. The large, sturdy handle makes it easy to lug from the car to the sand. When you're ready for a drink, flip up the straw and take a sip. The wide mouth provides easy access for packing ice inside. Then you can stay cool for hours under the South Carolina sun. It can leak when it tips, but that doesn't often happen with such a broad base. Forty ounces isn’t enough? Go for the 64-ounce option when you need a drink to keep you going for hours on end, although you may want to opt for the 22-ounce when you’re biking across town.

See Details & Buying Options

So there you have it, a travel water bottle to fit nearly any need. From the city to the forest to the subcontinent, having a way to stay hydrated will help you make the most of your trip. No matter what niche you need your water bottle to fill, we think one of these will get the job done!
