Beside being super interesting and unique, they’re also ultralight. Ideal for everything from hiking to long-haul flights, these bottles are perfect travel companions.
In this guide, I’ll share with you my tried and tested best collapsible water bottles. They are so great you’ll find moving without them unthinkable!

LifeStraw Peak Squeeze
KEY FEATURES (34 OZ)
PROS
CONS
The LifeStraw Peak Squeeze is not just a collapsible water bottle. It’s a complete water filtration system. Durable, intuitive, and versatile, this bottle stands out from all the collapsible bottles I’ve tried.
Key Features
The Peak Squeeze is a collapsible bottle that will save you a lot of space in your pack. When full, it’s about 10 inches long and four inches wide, and when empty, you can compress it into the size of your fist.
I like to remove the filter, roll it up, and tuck them together in my backpack’s back pocket.
This bottle also comes with the filter that protects against bacteria and protozoa, meeting U.S. EPA and NSF P231 standards for removing these contaminants.
You can drink filtered water directly from a stream or fill the soft bottle and squeeze the water into your mouth. The options are super convenient!
To top it off, this filter works efficiently right out of the box, unlike some filters that need multiple uses before allowing water to flow through easily. It doesn’t take much effort to squeeze the water through, making refill stops quick.
The durability of the Peak Squeeze is fantastic compared to similar bottles. The dust cover on the drinking straw is built to last and is made of thick, hard plastic that screws on securely. After nearly a year of use, it hasn’t developed any leaks.
Potential Pitfalls
Being a collapsible bottle with a filter, the Peak Squeeze does require more maintenance than other bottles.
For optimal flow rates, regular backflushing is necessary. You should also store the filter in a saline solution to keep the filter from drying out and maintain the membrane’s hydrophilic properties.
Verdict
The LifeStraw Peak Squeeze tops our ranking of the best collapsible water bottles and for good reason.
If you’re heading into the backcountry for more than a few hours, you’ll need to refill your water. With portable filter options, there’s no reason to risk an infection that could put you out of action for weeks.
The LifeStraw Peak Squeeze is not just “worth it”. It’s worth every penny!
HydraPak Flux+ 50 oz. Water Bottle
KEY FEATURES
PROS
CONS
Collapsible water bottles with integrated filters are absolutely revolutionizing the outdoor game, and I couldn’t be more thrilled. These all-in-one are perfect for getting clean water in the wild and when you’re on the go.
The HydraPak Flux, in particular, is a standout superstar. If you haven’t tried one yet, you’re seriously missing out!
Key Features
First things first, HydraPak Flux is available in two versions: HydraPak Flux+ with a filter AND HydraPak Flux without a filter. Initially, I wanted to buy the version with a filter, but I ended up with the basic version and had to order the filter separately later on.
If you choose the version with the filter (which I highly recommend), you won’t be disappointed. It effectively removes common waterborne bacteria like E. coli, parasitic cysts per EPA Guide Standards and NSF P231, and even microplastics greater than or equal to 3.0 microns in size per NSF 42.
On top of its efficacy, I love how compact the HydraPak Flux can get. When scrunched down, it’s about the size of a softball and can get even flatter if you remove the filter.
On top of that, it has a loop on top that serves two purposes: clipping your bottle onto your backpack and folding over the scrunched-up bottle to keep it compac. This is something that I miss in the LifeStraw Peak Squeeze, for example.
The material and overall shape of the HydraPak Flux are noteworthy too. It’s got a flat bottom, which means when the bottle is full (but only when it’s full), it can actually stand up by itself.
Potential Pitfalls
Cleaning the HydraPak Flux isn’t exactly what I’d call “easy”. The filter itself is tough to clean, and you can’t just throw the bottle in the dishwasher.
However, with a bottle brush, you can scrub the insides pretty easily. Just don’t expect it to sparkle without a little elbow grease.
Also, you might notice a plastic taste in your new HydraPak – it’s a thing with this bottle. But there’s a simple fix. Just squeeze the juice from a whole lemon into the bottle, fill it with water, and freeze it. Once it’s frozen, take it out, let it thaw, and give it a rinse.
Verdict
The HydraPak Flux offers all the benefits you’d expect from a top-tier bottle in the collapsible bottles category. Its collapsibility is stellar, its filter lets you drink water from nearly any source, and it’s designed to be as small and light as possible.
Hydaway Collapsible Water Bottle
The Hydaway bottle is my absolute favorite for travel, thanks to its awesome collapsible design that shrinks from 8 inches to just 1.5 inches. I’m totally in love with this water bottle, especially for airport trips where space is tight but staying hydrated is a must!
Key Features
The Hydaway looks different than other collapsible bottles due to its flexible, accordion-like design that allows it to fold down to the size of a small jar lid. Simply scrunch it down and slide it into your pocket – it’s that easy and convenient.
The Hydaway is impressively leakproof too. The soft material combined with a tight-fitting lid means you won’t have to worry about any dents or spills.
However, there is a small caveat. While the spout lid is generally reliable, it can sometimes leak a bit when you’re drinking from it. If you squeeze the bottle too hard or tip it over too severely, a few drops might escape. But when the spout is closed, the seal is tight, and there’s no leakage.
However, I wouldn’t recommend tossing a fully-filled Hydaway inside your backpack. It wasn’t really designed for that. If I need to carry it full, I prefer attaching it to the outside of my pack with a carabiner.
Unlike other collapsible bottles, the Hydaway is relatively easy to clean, even with all its nooks and crannies. It’s dishwasher-safe, but on my adventures, I’ve been hand-washing it (finding a dishwasher on the go is a rare and magical occurrence!).
Potential Pitfalls
While I wouldn’t say that the Hydaway bottle has glaring flaws, it does have some inconveniences that you should be aware of.
The first one is related to the grip. Imagine trying to firmly hold something soft and flexible, only to find it slipping through your fingers. That’s the experience with the Hydaway. It’s a bit tricky to hold while drinking unless you grip it by the center ring or the mouth.
And while I said that this bottle is relatively easy to clean, you might struggle to reach the deepest parts if you have larger hands. Fortunately, the bottle’s flexibility comes to the rescue! You can nearly turn it inside out, which aids greatly in the cleaning process.
Verdict
The Hydaway is like no other bottle out there. Designed as the ultimate collapsible water bottle for travel, it’s far from a one-trick pony. It may not have insulation, but it excels in almost every other scenario. I bring it to the gym, use it at work, and even take it on my hikes.
If you’re searching for a collapsible bottle that’s not only functional but also makes a statement, this is the one.
Platypus Platy 70 oz.
KEY FEATURES
PROS
CONS
If you’re on the hunt for a reliable, budget-friendly collapsible bottle for your backcountry adventures, the Platypus Platy is the answer.
Compact yet boasting an impressive capacity, it’s surprisingly durable for just $15. Whether I’m hiking, biking, or kayaking, this trusty water bottle never lets me down.
Key Features
When I first got my hands on the Platy bottle, I’ll be honest – I was skeptical. This collapsible wonder looks like it wouldn’t stand a chance against a traditional bottle. Yet, here it is, blowing my expectations out of the water.
Its compact and flexible design lets you flatten it when empty and roll it up to fit practically anywhere in your backpack or travel bag. No kidding, you can stuff this thing into the tiniest crevices.
When full, though, it stands on its own nicely – a pleasant surprise for such a flimsy-looking bottle.
But the biggest highlight of this bottle must be its light weight. Compared to a hard bottle of equivalent volume, the Platy bottle is 80% lighter.
At just 1.3 ounces, it’s a featherweight champion and it takes up a mere 1/5th the space when empty compared to traditional bottles. Even for most collapsible soft bottles, that’s remarkable.
In fact, it’s the lightest water bottle I’ve ever owned, and despite its dainty appearance, it holds a whopping 70 oz. of water. That’s nearly two liters!
You’ll be amazed at the durability of this bottle. Once, I dropped a full one from the top of my pack onto a sharp rock. It only got a tiny hole, which I easily fixed with waterproof medical tape. Truly, it’s built to withstand your wildest adventures!
Potential Pitfalls
Drying this bottle is a patience game. The small opening and large volume are the reasons why it takes forever to dry it after cleaning. I live in a dry climate, and it still takes a good two to three days to air out completely. I can’t imagine how long it would take in a humid place!
Also, keep an eye on that cap as it’s easy to lose when you’re refilling or attaching a water filter. Nothing’s more annoying than misplacing the cap and having to jury-rig a solution in the middle of nowhere.
Verdict
The Platypus Platy is a hidden gem. At just $15, you might think it’s a cheap knock-off that won’t last. But this bottle is different.
It may not have all the fancy features of the LifeStraw Peak Squeeze, but it’s a reliable workhorse that will stick with you for thousands of miles.
What Is the Point of a Collapsible Water Bottle?
The main point of collapsible water bottles is portability and convenience. Ever found yourself lugging around an empty water bottle, feeling like it’s taking up more space than a small dog? A collapsible water bottle solves that problem in one simple fold.
You can stuff it in your bag without a second thought. It’s there when you need it and gone when you don’t. Imagine the convenience when you’re traveling or just out for a day!
How to Use a Collapsible Water Bottle?
Using a collapsible water bottle is as simple as it is genius. It saves space, keeps you hydrated, and adds a touch of adventure to your daily routine. Here’s how to use it right:
- Unfolding. Start by giving the bottle a good shake, which will help it pop out more easily. Then, pull the sides gently until it’s fully extended.
- Filling it up. Open the cap and pour in your water but don’t overfill. Collapsible bottles can be a bit wobbly when standing upright, so filling them to the brim can lead to accidental spills.
- Drinking. It’s simple: just open the cap and sip. But here’s an unexpected twist – some collapsible bottles come with a built-in filter. If you’ve got one of these, you can fill up from streams or taps without worrying about nasty contaminants.
- When you’re done, it’s time for the collapse. You’ll want to squeeze out as much air as possible before folding it. Start from the bottom and roll it up towards the top, like you’re packing up a tent. Secure it with the attached strap or clip.
What Materials Are Used in Collapsible Water Bottles?
Silicone is a material that you’ll come across often while searching for a collapsible water bottle. It’s flexible, durable, and safe for food. You can squish these bottles down to fit in your bag without breaking a sweat.
BPA-free plastic is also a frequent sight. It’s lightweight, easy to clean and you don’t have to worry about harmful chemicals creeping into your drink.
Some collapsible water bottles also use stainless steel, but usually for their bases or spouts. It adds strength where it matters and keeps your water tasting fresh.
Are Collapsible Water Bottles Worth It for Travel?
Collapsible water bottles are definitely worth it for travel because they save space, lighten your load, stand up to wear and tear, and help you be a more eco-friendly traveler.
What surprised me the most is that I subconsciously replaced my traditional stainless steel and plastic bottles with collapsible ones whenever I was about to travel.
That’s mainly due to their outstanding space-saving abilities. Traditional water bottles are clunky and take up space even when they’re empty. But with a collapsible bottle, you can squash it flat or roll it up when it’s not in use.
Are There Downsides?
A few. Some collapsible bottles might have a bit of a plastic taste initially, but that fades over time. And, occasionally, they might be a bit tricky to dry completely. But these are rather minor inconveniences when we consider the overall benefits.
Conclusion
Collapsible water bottles offer a fascinating alternative to traditional bottles, especially if you travel frequently.
But don’t just think of them as a one-trick pony. Many of these bottles can seamlessly integrate into your daily life, performing their duties exceptionally well.
Now, will they completely replace my insulated stainless steel bottles? Probably not. Sometimes, they can be a bit tricky to clean, and there’s always that slight risk of a wet bag if you’re not careful.
But despite these minor quirks, I have found real value in investing in them, and I’m confident you will too.
Frequently Asked Questions (FAQs)
Are Collapsible Bottles Safe?
Collapsible bottles are completely safe and they are free from harmful chemicals as they are usually made from food-grade silicone or BPA-free plastic.
Cleaning is another thing you might worry about because no one wants to sip from a dirty bottle. Luckily, most collapsible bottles are dishwasher safe.
Are Collapsible Water Bottles Hard to Clean?
The construction of collapsible bottles, with their flexible sides and narrow openings, can make it challenging to get them fully clean and dry. Ensuring that no residue remains in every corner and crevice can be difficult.
And while most of these bottles are dishwasher-safe, think about those times you’re out hiking or exploring where dishwashers are not readily available. You need to wash your bottle right there and then, using whatever resources you have on hand. Suddenly, a simple task becomes a test of your resourcefulness.
How Do You Clean Collapsible Water Bottles?
- First things first, always rinse right after use. It’s tempting to leave it for later, but you don’t want any remnants festering inside.
- When you’re home, toss it in the dishwasher. Most collapsible bottles are safe for that. When you’re out and about, you’ll need some basic tools like a small brush that will help reach tricky corners.
- Fill the bottle with warm water and a few drops of mild soap. Give it a good shake – I mean really shake it. Picture yourself as a cocktail mixer, only instead of a drink, you’re aiming for cleanliness.
- Rinse thoroughly. Run clean water through it several times. You don’t want any soap residue left behind, making your next sip taste like a bubble bath.
- Drying is crucial as leaving moisture can lead to mold. Roll out the bottle and let it air dry. If you’re in a hurry, pat it down with a towel. But be thorough – moisture hides in those creases.
Here’s a little trick I picked up: toss some dry rice inside along with soapy water. The rice scrubs the interior as you shake it.
How to Get Smell Out of a Collapsible Water Bottle?
To get smell out of your collpasible bottle, you need to act fast. The longer those smells linger, the harder they cling.
- Start by filling your bottle with a solution of warm water and white vinegar. Leave it soaking for a few hours.
- After your vinegar soak, give the bottle a good rinse. You don’t want to taste vinegar in your next drink unless you’re into that sort of thing.
- Next, add a spoonful of baking soda and fill it with warm water. Shake it up like you’re mixing the best cocktail at a summer party and let it sit for another hour. Baking soda will help neutralize any remaining odors.
- Now, you may use a little trick I swear by. Put a couple of lemon slices inside the bottle, fill it with water, and let it sit overnight. The lemon not only smells amazing but also adds an extra layer of freshness.
- Rinse thoroughly again. And I mean really rinse. You don’t want any leftover baking soda or lemon bits turning your water into a science experiment.
- Finally, let your bottle air dry completely. If you’re in a hurry, use a clean towel to dry it, but make sure every nook and cranny is bone dry.
Do Collapsible Water Bottles Keep Water Cold?
Collapsible water bottles don’t keep your water cold for long because they are usually made of silicone or plastic. These materials are great for flexibility but not exactly known for their insulating properties. If you fill one with ice-cold water, don’t expect it to stay chilled for hours on end, especially in the heat.
When it comes down to it, if keeping your water cold is a top priority, you might need to bring along an insulated bottle. They’re bulkier and don’t collapse, but they get the job done. It’s a trade-off between convenience and temperature control.
Can You Freeze a Collapsible Water Bottle?
Yes, you actually can freeze your collpasible bottle but with caution. Most collapsible water bottles are made of silicone or flexible plastic. These materials can handle the freezing process, but they’re not invincible.
That said, if you fill it to the brim and freeze it, the expanding ice could distort the shape or even damage the bottle. That’s definitely a plot twist you’d rather avoid.
The solution? Only fill your bottle halfway before freezing. This way, there’s room for the water to expand. After it’s frozen solid, top it off with water.
Do Collapsible Water Bottles Sweat?
Yes, collapsible bottles do have a tendency to sweat because they usually lack insulation. They fold up wonderfully but don’t stand a chance against basic physics.
If you fill it with ice-cold water and the temperature outside heats up, condensation will most likely build up on the outside of your bottle.
To combat this, I’ve tried wrapping my bottle in a small towel. It’s not the high-tech solution we all dream of, but it does the job fine.
If sweating bottles drive you nuts, you might need to consider an insulated bottle. They’re bulkier and don’t collapse, but they keep your water cold without the sweat. It’s a bit of a trade-off.
Can You Bring a Collapsible Water Bottle on a Plane?
Yes, you can bring a collapsible water bottle on a plane. The trick is to make sure it’s empty when you go through security as TSA agents don’t have a sense of humor about liquids over 3.4 ounces (100 milliliters).
Once you’re past security hurdles, you can fill your bottle at any water fountain or café. Some airports even have fancy hydration stations just waiting for you.
