Carrying around a 64 oz. water bottle might sound like a workout in itself, but most of these hefty hydrators come with benefits that smaller bottles usually don’t, such as a sturdy build and, of course, a bigger capacity.
Personally, I love this capacity because a water bottle this big has got your back for the entire day, or even two, without needing a refill. Pretty handy!
Stick around as we discuss the best water bottles with 64 oz. capacity and what makes these giants stand out in the crowd.

Hydro Flask
KEY FEATURES
PROS
CONS
I’m definitely part of the Hydro Flask fan club, having snagged five of them in various sizes. It’s not just their popularity that draws me in; they’re simply that GOOD.
In my tests, they scored a solid 4.62 out of 5 stars, earning the title of the best water bottle out there. The 64 oz. Hydro Flask is no exception, delivering the same awesome qualities as the smaller sizes.
Key Features
This Hydro Flask has won my heart and trust for several reasons, but its versatility tops the list. It’s sleek, durable, and with a 64 oz. capacity, it’s the perfect size for almost any adventure or just a day at the office.
I especially like how portable my Hydro Flasks are. Sure, they aren’t the lightest options out there, but the comfortable and flexible straps (which fit four fingers easily) make carrying even the hefty 64 oz. version much easier than other bottles.
Durability-wise, this bottle can handle a few bumps and bruises easily. The powder coating acts like armor, making it way more resistant to scratches compared to other bottles without it. It gives you a much better grip too.
But the reliable insulation performance is where the Hydro Flask turns from good to great. Whether you’re a coffee lover who sometimes forgets their brew and finds it still hot hours later, or someone who can’t stand lukewarm water, this bottle delivers.
I once left mine in the car with some ice for over two days, and I swear, the water was still as cold as if I had just filled it! It’s pretty amazing how it keeps drinks hot or cold for such a long time.
Potential Pitfalls
It’s tough to find a single negative thing to say about this bottle and sometimes it feels like it was designed in a lab to tackle my pickiness.
But if I had to nitpick, it would be the weight. While it’s super versatile, lugging around a 64 oz. bottle that weighs over 2 pounds can get pretty heavy after a while. On the plus side, this is a common drawback with larger bottles, so I guess it’s not just me!
Verdict
If you’re on the fence about getting a Hydro Flask, I say go for it! This bottle has been super reliable for me, keeping my drinks just how I like them, no matter where I am or what I’m up to.
Sure, the $65 price tag might feel a bit high, but for a product that performs this well and lasts, it’s well worth it. After all, it’s no accident that Hydro Flask topped the charts in my bottle tests.
Coolflask
KEY FEATURES
PROS
CONS
Coolflask is a newer brand in the water bottle market, and it really shines with its fantastic value for the price and decent insulation performance. There’s so much to love about this bottle!
Key Features
Unlike many high-end brands that slap a hefty price on their bottles, Coolflask justifies its $44 tag for the 64 oz. bottle by throwing in some awesome accessories.
You get:
- a stylish cover with a strap,
- three different lids,
- two straws
- a handy little brush for cleaning.
When you combine these extras with a top-performing bottle, you’re really getting a great deal!
My favorite feature is the cover with an over-the-shoulder strap simply because it makes carrying my big, heavy bottle so much easier. Honestly, it just looks cool to sport a 64 oz. bottle this way!
The three different lids are a fantastic bonus too. They’re not quite as high-quality as the ones you’d find in a Hydro Flask, but I’d not call them flimsy by any means.
The screw-on lid with a flip-up handle makes ice refilling easy. The spout lid is perfect for sipping hot drinks, while the straw lid is ideal for enjoying cold beverages.
But that’s not the end of surprises as the insulation performance of this bottle is decent too.
During my tests, the Coolflask kept my water cold for a full 24 hours, going from 32°F (0°C) to 53.8°F (12.1°C). If you throw some ice in there, Coolflask’s claim of keeping it cold for 48 hours is definitely within reach.
The heat retention is solid as well, though my tests showed it can’t quite hit the promised 24 hours – more like around 12.
Potential Pitfalls
It’s tough not to love Coolflask, but it has one big downside: it’s not dishwasher safe. Thankfully, the bottle and lids are easy to clean by hand, but it’s a bit of a letdown when I can’t just toss my bottle in the dishwasher.
Verdict
Coolflask is aptly named because it truly is a…cool flask! With its fantastic features, handy accessories, and a reasonable price, I believe Coolflask is the perfect alternative to pricier 64 oz. bottles.
Klean Kanteen TK Wide
KEY FEATURES
PROS
CONS
At first glance, the Klean Kanteen TK Wide might not seem as eye-catching or exciting as some other bottles in this ranking, but it boasts the best insulation performance you can imagine.
Key Features
Let’s kick things off by highlighting the standout feature of this bottle (or should I say thermos?) – its amazing insulation capabilities. During my tests, it kept my water ice-cold for 24 hours without any ice, with the temperature only climbing from 32°F (0°C) to 47.7°F (8.7°C).
Honestly, I think if I had left the water in there even longer, it would still be refreshingly cold after two days! And that’s all without ice. If you decide to toss some ice in, I’m pretty confident the TK Wide can keep your water cold for the full 147 hours it promises (that’s over 6 days!).
The heat retention is just as impressive; you can definitely count on your tea or coffee staying hot for 40+ hours.
This Klean Kanteen bottle isn’t just great for insulation as it’s also quite durable. Made from high-quality 18/8 stainless steel, it features thicker walls at the bottom to prevent dents.
Potential Pitfalls
I really love the overall performance of my TK Wide, but I do have a few issues with the cap. First off, it has this tiny metal handle that just doesn’t feel comfortable to hold, and honestly, it isn’t.
The cap itself is pretty small, making it tricky to open. You have to grab it by a little edge, and if your hands are wet or sweaty, good luck, your fingers will definitely slip.
Verdict
The Klean Kanteen TK Wide is hands down the best 64 oz. bottle if insulation performance is your top priority. It’s totally worth the $65 I spent on it and whenever I need my drinks to stay cold or hot for a long time, I always grab my Klean Kanteen.
YETI Rambler Half Gallon Jug
KEY FEATURES
PROS
CONS
The YETI Rambler half-gallon jug is one of the few items I consider bombproof. Sure, it has its quirks and a couple of drawbacks, but I absolutely love bringing it along camping, to the beach, or even just for family gatherings.
Key Features
The Rambler jug is an absolute beast of a bottle, crafted from kitchen-grade 18/8 stainless steel with thick walls, especially at the bottom. This durability is a hallmark of all Rambler bottles, but the half-gallon jug takes it to another level!
It’s almost invincible against dents if you drop it, resistant to scratches, rustproof, and even dishwasher-friendly.
One feature I absolutely love is its giant opening. Cleaning water bottles has always been a chore for me, especially when they start growing bits of mold inside.
With this jug, that worry disappears. Its opening is so huge you can easily see and clean every inch inside.
The lid of this jug is another highlight. The inch-thick insulated lid screws on and off effortlessly and comes with a large pour spout covered by a small cap. This cap attaches magnetically to the jug’s lid, a clever design choice to prevent it from getting lost.
I’ve sparked countless conversations by demonstrating how the cap snaps back into place on the lid.
What about insulation? With its double-wall vacuum design and a full inch of insulation, this jug keeps your drinks close to their original temperature for about a day and a half, but there’s a catch: you need to load it up with plenty of ice.
Without ice, the insulation isn’t as impressive; it managed to keep my water cold for roughly 12 hours. So, while it may not be my top choice for insulation among my 64 oz. bottles, I simply toss in a quarter of the jug’s capacity in ice, and honestly, I can’t tell the difference between my Rambler and other bottles.
Potential Pitfalls
Weight is definitely something to think about. At 3 lbs. 8 oz. when empty, it’s considerably heavier than other options. However, the durability you get in return more than compensates for that extra weight. After a bit of time, I found myself getting used to it.
While I can’t picture anyone walking miles with it in hand, it is a YETI product. Let’s be real – YETI gear tends to be on the heavier side, and most buyers know this and typically use their bottles in stationary settings, like camping, for example.
Some folks have pointed out the struggle with opening the jug. It’s definitely not the easiest thing to do! However, with a little practice (like using a “one-arm hug” while twisting the handle) you can get the hang of it.
Just be ready for the fact that it might not be the most enjoyable experience. I once spent a solid 10 minutes trying to get the lid off because I had tightened it so much. Let me tell you, my face was a bright shade of red after that!
Verdict
At $100, the Rambler is very expensive, but I find myself reaching for it more often than my other bottles of the same size.
While it might not rank as the absolute best, if you’re looking for something high-quality and a bit unique compared to standard bottle designs, the Rambler is definitely the way to go.
And if you don’t like the jug design of this model, check out the YETI 64 oz. water bottle. Personally, I don’t own it, but it has the same capacity and capabilities to the Rambler jug.
Under Armour Playmaker
KEY FEATURES
PROS
CONS
Whether you’re smashing it on the soccer field, hitting home runs in baseball, or sprinting around the track, the Under Armour Playmaker is one of the best 64 oz. bottles that you can get for your active lifestyle while not breaking the bank.
Key Features
What surprised me most about this bottle is that it has two handles, giving you two options for carrying it. I personally like using the flexible handle on the side, but the sturdy top handle is pretty handy too!
Another awesome surprise is the handy hooks on the lid that let you hang your bottle on the fence while you play. It’s the only bottle in my collection with this feature, and I find myself using it surprisingly often on the pitch.
The Playmaker is made from polypropylene instead of stainless steel, so I wouldn’t bet on it lasting for years. However, it’s surprisingly durable for just $25 and can handle a few drops without issue.
But there’s more! I also found out that the Playmaker is 100% leakproof, thanks to a clever locking mechanism shaped like a small pin. This little feature keeps you from accidentally pushing the button and opening the cap.
Potential Pitfalls
The insulation performance is pretty much what you’d expect for the price. It keeps your drinks cold for up to 10 hours in moderate conditions, but that drops to about 3-4 hours on hotter days.
For most practice sessions or games, that’s more than enough to keep you refreshed, but it definitely doesn’t compare to stainless steel bottles. That’s why I load up on ice whenever I’m about to hit the field.
The biggest downside for me was the smell and that plasticky taste right after I bought it. It eventually faded, but it took a bit of time and some cleaning to get rid of it completely.
Verdict
The Under Armour Playmaker bottle is a solid choice for athletes looking for an affordable, functional water bottle. Its insulation keeps up reasonably well, it’s easy to carry, and it fits perfectly into active lifestyles.
There are a few hiccups, but for just $25, it offers good value and keeps you hydrated during crucial moments of play.
Do You Need a 64 oz. Water Bottle?
If you’re someone who spends a lot of time outdoors, be it hiking, camping, or engaging in sports, a 64 oz. water bottle could be a much better choice than a smaller one.
Let’s say you’re out in the sun, miles away from any source of clean water. In scenarios like these, having a large water bottle helps you stay hydrated longer without the hassle of refilling every hour.
Then there’s the work aspect. If you’re stuck at a desk for the majority of the day, getting up to refill your water bottle can become an unnecessary distraction. Having a 64 oz. bottle with you means you’ve got your hydration needs covered for the day, allowing you to focus on your tasks.
How Big Is a 64 oz. Bottle?
When you hear “64 oz. bottle,” it might be a bit hard to picture just how big that is. So, how big exactly is a 64 oz. bottle?
Imagine you have a regular kitchen measuring cup. Now, fill it up to the 8-ounce line. That’s about one cup of water. To fill up a 64 oz. bottle, you’d need to pour eight of those cups into your bottle. It’s quite a lot when you think about it that way!
In more relatable terms, think about those large soda bottles you see at the grocery store. They’re usually about 2 liters. Well, 64 ounces is just shy of 2 liters (which would be about 67 oz.). So, a 64 oz. bottle is pretty close to that size, but just a tad smaller.
Is a 64 oz. Water Bottle Too Big?
A 64 oz. water bottle isn’t too big if you spend a lot of time outdoors, work from home, or simply forget to drink water unless it’s right in front of you. In these scenarios, it’s actually a brilliant solution.
How Many 64 oz. Water Bottles Should I Drink a Day?
Health experts often recommend drinking about eight 8 oz. glasses of water daily, which adds up to 64 oz. If you’re someone who struggles to hit that target, having a bottle that holds your entire daily quota can be very useful.
It’s like having a daily goal sitting right there on your desk or in your gym bag, encouraging you to keep sipping.
But carrying around a 64 oz. water bottle isn’t always practical. These bottles are sizeable and can be quite heavy when full (usually around 2-3 pounds).
If you’re always on the go, darting between meetings, or if you have a smaller frame, lugging around a bottle that big might feel like a workout in itself.
Conclusion
The thought of carrying around a 64 oz. bottle might sound a bit intimidating at first and I had those same thoughts at first.
But after testing out the five bottles (or jugs, if that’s what you prefer to call them) listed in this guide, I’ve been convinced of their value in a variety of situations.
Whether I was out hiking, camping, engaging in some intense physical activity, or just stationed at home working remotely, these bottles proved to be more than just containers for water.
Holding your (almost) entire daily water intake in one single place is practical and incredibly motivating. Seeing your progress through the day encourages you to keep sipping, ensuring you stay hydrated without the constant need for refills.
Once you get into the habit of using one, going back to smaller bottles just doesn’t feel the same.
