Water bottles come in many designs and styles. They all have specific function and different advantages to their side. Even though you have a map of water sources, carrying a large amount of water is still essential for safety.

The average amount of water a person should consume in a day is 2 liters. That means that one backpack trip could take up a lot of space and weight. All things considered, if there is a way to avoid or this issue, everyone would go for it. The best collapsible water bottle offers this choice to backpackers.

Among the reviewed and rated collapsible bottles there were a lot of variations. All collapsible bottles are specifically designed to save space and weight. If you believe regular water bottles are not versatile enough or you find them too heavy; this article is just right for you.


Collapsible bottles are made from durable and flexible plastics and are made in two types; bottles with hydration bladder purpose or expandable bottle. The main purpose of these bottles is to save you some space in your backpack which could be used for something else, yet carrying the same amount of water inside.

Who are collapsible bottles intended for?

Collapsible bottles are used mainly by backpackers, bikers, hikers and everybody else who have the need to save some space. Regardless of the reason you are using them for, they can easily be contracted and stored in your pocket until you get to your next water source.

Why should you use them?

If you are in doubt whether a collapsible bottle would be the right choice for you, read through the following reasons for doing so and decide for yourself.

In the past collapsible bottles were being considered as a vulnerable technology, which is why they were being avoided. Nowadays, the material they are made of is thicker and they are less vulnerable to leaking or punctures. Also they used to cost much more than a traditional bottle. However, now they run at a lower cost and they are more durable.

Reusable bottle

When it comes to one or few bottles, collapsible bottles seem to be unnecessary. However, when you are going on a longer hike, a larger amount of water is needed. If you are familiar with planning water sources, you certainly know that they don’t always come as expected.

They could be contaminated from a previous day rain or dried up. Having a foldable bottle in these occasions could come quite practical and could give you many additional hours without dehydration.

Things to consider when buying collapsible bottles

A good quality collapsible bottle should be reusable and washable. That’s why they usually have a higher price, and this is almost always the case, although it should be specifically stated by the manufacturer.

There are bottles made from thinner plastic and are not reusable. These bottles are not recommended since even a small amount of heat, like a direct sun light, could make them release toxic plastic chemicals in your water. For this reason, the thickness and the type of the plastic matter. All the reviewed products in this buying guide are made from safe plastic (that doesn’t contain harmful chemical coating in the inside of the bottle).

Plastic bottles

Most plastic products are made from recyclable plastic, whereas hard plastic bottles are almost always made of non-recyclable plastic. The collapsible bottles are made from three layers of plastic that saves you from the harmful plastic chemicals and serves as a proof they could last for years.

Even though it is recommended to replace your bottle every year, the collapsible bottles are durable enough to support your backpacking trips for years to come.

Another feature which would be useful when you are backpacking in cold mountains is the ability of the bottle to endure any temperature. This means that you could use your bottle for hot and cold water or other beverages. If you are thinking why would you need to use hot water while backpacking, the reason is to ensure your safety.

If there is a contaminated source, or even a chance for a potential contamination, boiling the water is a good idea. It won’t kill the viruses and bacteria as some water purifiers do, but it will get rid of some impurities usually found in water.

If other than boiling equipment you also have iodine pills and a filter, there is a great chance this would do the job. On the other side, if you are planning on climbing some colder areas, this bottle would act as a thermos and prevent the water from turning to ice.

The dimensions are another feature to consider. There are various dimensions you could choose from, however, make sure you make the most suitable choice for you. This means that you need to calculate the length of the trip you are planning on taking and the available water sources around. Comparing this with the recommended daily amount of 2 liters will show you how much water should your bottle be able to carry, thus its dimensions.

Hydrapack bottles

There are some materials out there which are spicing up the water you put inside them. The problem is that the spice is plastic. For this reason, when buying a collapsible bottle make sure its materials are taste free. All of our reviewed and tested bottles are taste free, at least for a certain amount of time. After few years of use, every plastic is starting to deteriorate and the bottle is starting to add a taste to the water.

The weight of the bottle is also important. In fact, the whole point of buying a collapsible bottle lies in its space and weight. All collapsible bottles are designed to be lightweight. However, the harder the plastic, the higher the weight. And the harder the plastic, that much safer for consuming the water inside.

The lightness of the bottle and the kind of plastic material which is being used is a feature you need to balance between. If you are planning to use it for the recommended time of one year, you could choose the lightest one on the market. However, if you are planning on replacing it after couple of years, than you should focus on the bottle’s material instead of its weight properties.

Collapsible bottle

There are also some bottles which are machine used, and some that aren’t. This is a relatively important feature, for the simple reason that only a machine washer is able to thoroughly wash the bottle. If you have been unknowingly putting contaminated water inside, the only way to destroy the bacteria is by washing them on higher temperatures in a washer.

Some collapsible bottles are extremely lightweight but their durability suffers for that. Choose a bottle with no extra leakage and one that doesn’t pop up easily in a bag. When looking for this feature you should consider the metal ring which slips over the lid in order to keep it in place. This could come quite handy in keeping your stuff nice and dry.

    Love, love, love the collapsible Baiji Bottle that I bought! It’s extremely lightweight, so it’s not going to be banging around against your body all of the time! It’s also cool that the bottle lies very flat when it does not have water in it. It’s just really good quality overall. I really could not be happier with it!

  • Russell McCarty

    It’s a great space saver and very compact. What I love about this product is the food grain silicon which is safe for our health. It is also stain and odor resistant, so you get excellent tasting water every time.

    I use the Aquabod Water Bottle a lot when I am travelling. What I like about it is that it collapses to a small enough size that I’m able to fit it neatly into my laptop bag. I’ve had it for quite a while now and can attest that the water doesn’t have any odd taste to it at all. I washed it out when I bought it, and now wash it about once a week and that seems to work pretty well.

    Hi Mike and thanks for dropping by. Actually the Aquabod Water Bottle is dishwasher-safe so you can just pop it inside the dishwasher everyday. The material is BPA-free silicone so it’s very safe to use. I wonder what color you got? Blue?
