It’s hard to imagine a time when reusable water bottles weren’t the norm. For most of us, school days were filled with frequent trips to water fountains, and later, consistent refilling of our old plastic water bottles which were offered to us at lunch or breaktime.
However, we’re unsure just when the shift from regular old, 250ml reusable bottles to whopping three-litre tankards occurred. Where in the past, older school kids used to gawk at Year 7s carrying backpacks larger than them, it’s now gigantic water bottles which dwarf the Secondary School newcomers.
The answer to potential overhydration and the back-breaking weight of the modern tumbler? Well, the humble collapsible water bottle, of course.
What are the benefits of a collapsible water bottle?
Without further ado, we’ve curated a selection of the best adventure-proof collapsible water bottles on the market.

Whether you're reaching your camping pitch by car or public transport, having a compact kit allows you to take more with you, upping your comfort levels.

ElifeAcc Collapsible Water Container Water Storage bag 2 Packs

Capacity: 5 litres x 2
Essentially a bag with a nozzle added to the top, this is one of the most streamlined carriers you can find. Each piece folds flat making it perfect for trips where you need your camping kit to be as light as possible, as well as for keeping in the car boot for emergencies.
While the plastic is robust, we would recommend a higher volume and sturdier design for long outdoor adventures. If you're looking to quench your thirst on a picnic, however, this is ideal.
