Introducing Duothirst

What Is Duothirst?

Duothirst is the world's first single nozzled bottle that can hold two drinks simultaneously. 

We all need to stay hydrated throughout the day and Duothirst allows you to carry any two drinks you desire, transforming the way you drink and stay hydrated forever.

We designed Duothirst to be the best bottle out there and to provide an attractive alternative to traditional single use plastic bottles. We wanted to make change through a great product, whilst also helping to tackle the plastic bottle pollution crisis. 

Say Yes To The Environment!

Did you know 1 million (1,000,000) single use water bottles are purchased every minute worldwide! A total of 480 billion bottles were bought and used in 2016. Of these 480 billion fewer than half were collected for recycling and just 7% of those collected were turned into new bottles. Instead most of these plastic bottles produced ended up in landfills or in the ocean.

Here at Duothirst one of our main motivations to develop such an innovative product, was to try and tackle the single use plastic bottle pollution crisis. We wanted to make a water bottle that everyone would love to use and would encourage people to stop using disposable water bottles. We feel so strongly about this that a portion of our profits will go to the great causes 4Ocean and WaterAid. Reducing the amount of plastic in the ocean and ensuring everyone has access to clean drinking water. So not only are you helping the environment by using Duothirst, but you're also helping us to make change and donate to these great causes by buying one. 

Use Duothirst Anywhere

One of the great things about Duothirst is its multi-use capabilities. The ability to hold two separate drinks at any one point in time makes Duothirst ideal for so many situations. 

Duothirst is perfect for: the busy on the go commuter trying to stay well hydrated. The sporty individual who is trying to achieve a healthier lifestyle, making Duothirst the ultimate training necessity. The student who is wanting to stay hydrated throughout their demanding day. Essentially Duothirst is perfect for anyone out there trying to stay hydrated and who loves having more than one drink throughout their day.

Unlike Anything Else

Starting from scratch, reimagining what a bottle could be and do, we set out not only to create a bottle, but to create a new class of water bottle that we call Duothirst.

We became fixated with the idea of having two drinks in one bottle, changing the way bottles have always been and building an extra layer of functionality onto the traditional approach.

We designed Duothirst to be more than just a water bottle. We wanted it to seamlessly fit into your lifestyle and give you the flexibility and choice of what you want to drink and when you want to drink it.

What Is BPA?

BPA (bisphenol A) is an industrial chemical used in plastic water bottles and many other plastic products. It has been used since the 1960’s to make certain plastics and resins. BPA has been found to cause your oestrogen levels to rise regardless of whether you are a male or female. Often plastic products which contain BPA have been found to leach when exposed to certain stresses, things like being exposed to temperatures as low as 15°C can cause this leaching to happen. Being exposed to this chemical and consuming it can lead to adverse health effects it has been associated with health problems such as; altered growth rates, early puberty in girls, reduced sperm count in males, altered functions in reproductive organs in both sexes, altered behaviour, obesity and higher rates of some cancers. Growing fears about the long term effects BPA plastics can have has prompted the EU, United States and Canada into banning the use of BPA in baby bottles.

At Duothirst Ltd all the plastics we use in our products are BPA free! We do this as a standard.

Yes, all parts of the Duothirst bottle are dishwasher safe. We recommend you clean your Duothirst using the dishwasher or by hand using warm and soapy water.
