The Founders

Justbottle was born in the UK in 2021 where our founders, Sam and Millie, reunited during the global pandemic after being separated by international border closures and both no longer working in the aviation industry. 

During their time working as airline crew they travelled to some far-flung countries and both saw first hand the damage that single use plastic bottles have on the ocean. If nothing changed, single use plastic would continue to ruin a place that’s special to both of them.

“Just” to them means to do what’s morally right, that’s why Justbottle is more than just a bottle. They created a reusable bottle company with one simple mission: to provide a lightweight, practical solution to the single use plastic problem. Carrying a reusable bottle with you all day shouldn’t feel like a chore.

Everyone’s used single use plastic in the past, we live in a culture of convenience and Millie grew up in a major city where tap water was undrinkable so buying plastic water bottles was an everyday occurrence. Everyone can be part of the solution too though, it's never too late to make a small change. Being more sustainable in a wasteful world is not always easy but doing something small is always better than doing nothing! 

Justbottle is the beginning of their journey, not only to do something good for the planet but also to make memories everywhere they go, they can’t wait for you to join them in the Just community!

The Design

"A reusable bottle is an everyday essential for us, but we found ourselves still shopping around for a better one, and sometimes not even taking it with us. We asked ourselves why. Were we being lazy? Or was there nothing on the market that suited all our needs. When we asked other about it, we found lots of other people were facing the same problem.

We wanted to create a bottle that we would use everyday. Something you not only CAN carry everywhere, but WANT TO carry everywhere.

You shouldn't have to compromise when you choose to use a reusable bottle, that's why our bottles are designed to last. Our team use the finest materials to ensure high performance, wherever you go.

Having our bottle material lab tested and inspecting every single bottle is part of our rigorous quality control process. This is our way of ensuring consistent quality, something that we know is important to our community"

" A reusable bottle should be built to last, otherwise what's the point? Justbottles are designed to be by your side from the conference call to the marathon finish line "
