The Best Collapsible Water Bottles of 2024
Whether you’re trekking through the wilderness or going on a relaxing stroll through the city, it’s essential that you remain well hydrated.
Reusable water bottles (especially insulated ones), however, are often bulky and heavy, and that can be a problem if you prefer to travel light or don’t want to carry a large bag during your daily outings.
So, what’s the solution?
Instead of abandoning your reusable water bottle, you might want to consider investing in a collapsible model made either of silicone or durable plastic; these bottles are ultralight, compact and easy to carry in a sling or bum bag, which makes them ideal for long trips, hikes and for travellers looking to shave every possible ounce from their pack.
On top of that, flat and collapsible water bottles are often much more affordable, which is perfect for any traveller on a budget!
To help you choose the best option for all your city and outdoor adventures, today we’ll take a look at 7 amazing collapsible water bottles that you should check out in 2024!

Material: TPU, PP, Nylon
Whether you’re hitting the trail, travelling or are just out and about for the day, the HydraPak Seeker 2L is a reliable, heavy-duty collapsible water bottle that is perfect for any activity!
Weighing only 2.6 oz (76g), the Seeker can be safely folded without ripping or breaking, allowing you to easily store it in your daypack without barely taking up any space.

In order to provide you with safe drinking water in the wild, the Seeker is also compatible with any 42mm threaded water filter, which including HydraPak’s own 42mm filter. Travellers going on long excursion in the outdoors might even want to consider the version of this bottle that comes with an already integrated, replaceable filter.

Weight: 3.9 oz ∙ 110g
Volume: 1L (also available in 650ml)
Material: Plastic
This collapsible water bottle is one of the most versatile options available on the market. With an integrated, removable filter to safely collect water in the wild and light, durable materials, the LifeStraw Peak 1L can just as easily be used for travelling and daily activities.
The LifeStraw Peak 1L only weighs 110g, and can be completely folded to become almost pocket sized; it can fold to an even smaller size when the integrated water filter is removed. A practical lashing point near the cap is a nice addition, as it allows you to secure the bottle to your pack by using a carabineer.
The bottle is made of BPA-free, ultra-tough flexible plastic, with a nice grippy texture that makes it easy to handle even with wet hands; all in all, it’s definitely heavy-duty enough to survive long excursions in the outdoors, although we did have one get pierced after an accidental drop which, admittedly, was our fault!

Weight: 2 oz ∙ 57g
Volume: 1L (also available in 350ml and 500ml)
Material: TPU, PP, Silicone
Extremely lightweight and durable, the HydraPak Stow is one of our favourites to use for ultralight travelling and trekking!
Weighing only 57g, the Stow folds down to a tiny size and will easily disappear into your pack.
A practical loop near the cap can be used to secure it with a carabineer, as well as hold the shape of the bottle when folded. Instead of a screw-cap, the Stow is instead equipped with a nozzle cap that allows for easier drinking while on the move.
Like the Seeker, the Stow is also made of durable BPA and PVC-free TPU plastic, ensuring it survives all of your trips and activities. It can also be filled with hot water to warm you up during cold nights, or frozen to be used as an ice-pack!
For practicality and safety while in the wilderness, the Stow is compatible with all 28mm threaded water filters, and with HydraPak’s own 28mm filtration kit.

Weight: 2.4 oz ∙ 68g
Volume: 650ml
Material: TPU, PP, Silicone
The Osprey Hydraulics 500ml Soft Flask is one of the most compact collapsible water bottles on our list. It offers great durability and quality at an affordable price, even thought the size might be a little on the small side if you’re planning on using it as your only bottle throughout the duration of your trip.
This bottle is extremely light, weighing only 2.4 oz (68g), and collapses to an absolutely tiny size, making it an ideal choice for travellers with the means to refill it regularly.
It also has a handy nozzle cap to make drinking on the go easier. It does, however, lack any kind of attachment system.
The Osprey Hydraulics 500ml Soft Flask is made of durable BPA-free plastic that is both elastic and durable, allowing it to easily be used even over rough terrain. The only drawback is that it is not compatible with water filters, limiting its use for long periods of time in the wild.

Weight: 1.3 oz ∙ 36g
Volume: 2L
Material: Plastic, Nylon
The Platypus Platy 2L is an incredibly light, made in the USA collapsible water bottle that offers a huge water volume with almost no additional weight. This makes it one of the best choices for ultralight packers, whether they’re heading for the trail or the airport!
The Platy 2l only weighs 36g, and as such you’ll barely even notice its there when not filled. It also collapses down to a very small size, allowing you to easily fit it in a sling bag or a pocket. It does, however, lack any external lashing or attachment points, so it cannot be secured to the outside of a pack without a water bottle pocket.
The bottle is made of BPA-, BPS- and phthalate-free plastic; it’s well built and durable in material, but slightly less when compared to the other options on our list. With that said, we find it’s a fair compromise for how light this bottle is!
The Platy 2l is compatible with the brand’s own water filter, creating a lightweight and efficient water filtration system for all your outdoor adventures!

It weighs only 2.25 oz (63.75g) and collapses down to a very small size. The cap, however, is pretty large, which allows for easy cleaning but also means this bottle will take up a little more space compared to the others on the list. A plastic loop attached to the cap keeps it secured when the bottle is open, and also works well secure it to your pack with a carabineer.
Like all Nalgene bottles, the Wide Mouth Cantene is made of Tritan; this ultra-tough plastic is extremely impact and abrasion-resistant, and is the perfect choice to bring out in the outdoors. It is also BPA and BPS-free, along with being freezable and usable with hot water.
