DUO: The 2in1 water bottle for hot & cold drinks

£10,153

End the struggle of carrying two bottles... Instead carry hot and cold liquids together in one with DUO! 

Get rid of the struggle of two bottles, take DUO with you anywhere, for all your favourite drinks combinations! 

THE LID  

NEAT & SIMPLE DESIGN

There are just 4 elements to the bottle (lid, straw and two bottles), making it easy to keep everything together. DUO not only ends the struggle of two bottles, but also has the ability to be split into two and used independently, if you so desire! 

BALANCE 

Having the inner and outer bottle sharing the same centre of gravity ensures greater stability. It allows for one bottle to be empty while the other is full and not cause the bottle to topple over.  

HIGHEST QUALITY MATERIALS

RECYCLED PLASTIC (rPET) 

The outer 1L bottle of DUO is made from rPET (recycled polyethylene terephthalate). This means we use recovered plastic (that would have otherwise reside in a landfill or worse, our oceans). We could have chosen to use virgin plastic, which is cheaper and far easier to source, but we believe we owe it to future generations to do everything within our means to preserve our planet

STAINLESS STEEL

The inner 350ml stainless steel bottle is double wall vacuum insulated meaning there is no transfer of heat from the hot liquids to the liquid in the outer bottle. It will keep your hot drinks hot and cold drinks cold. Stainless steel is also reusable and can be easily recycled.  

BPA FREE & LEAK PROOF

From the lid to the straw and to the outer and inner bottles, DUO is 100% BPA free and of course, totally leak proof!

ONE BOTTLE TO RULE THEM ALL!

We carefully considered the best features of bottles available and aimed to improve on them, when we designed what we believe to be the best possible drinking experience. Thats why we came up with the rotating straw nozzle for quick hydration and raised neck design to safely sip hot drinks.

We’re Sarah and Ed, and this is the story of how we came up with DUO. 

The idea was born from our own frustrations. With the plastic epidemic having become increasingly evident, we made the decision to live more sustainably. The starting point for us was to cut out single-use plastics in the form of water bottles and coffee cups, replacing these with reusable bottles. However, doing this wasn’t as easy as we first thought. Being big coffee drinkers, it was common for us to stop by the local cafe en-route to work for our morning coffee fix. This meant, to follow our sustainable living mission, we would need to start carrying a second bottle for our coffee, alongside the bottle we already had for water to keep us healthy and hydrated. We soon found that having two bottles was bulky and required a large amount of space in our bags; it was just inconvenient

We needed an easy solution that would help us carry our coffee and water in a space saving, easy and convenient way. After hours of searching we found such an invention did not exist, so we decided to create our own! 


Risks and challenges

Sometimes unintended things happen which can cause delays and so in an effort to be totally open and honest, we have listed below what we believe to be the key risks in bringing your DUO to you within the timeline.

Product testing:
Before we create the final moulds to be used in DUO’s production, we will carry out final prototype testing. While we have a prototype that we think rocks, we won’t begin production until everything is perfect.

Manufacturing:
Our manufacturer is ready and raring to go and in possession of all the information needed. We don't foresee any difficulties, but if moulds need re-constructing this could mean delays. However, we have allowed for such eventualities in our timeline, so without such delays, we should be able to get your DUO to you sooner than November!

Fulfilment:
Rest assured, we have a crack team in charge of getting your DUO to you, this being an experienced global logistics company who have a long relationship with our manufacturer. Parcels can go missing or get damaged in transit and if they do, we will send you a replacement.

We will be sure to update you with any such issues and of course keep you informed as to when you can expect to receive your DUO. Neither of us want this to be a campaign that drags on (we have big plans!) and we promise we will devote ourselves to bringing you your DUO as soon as possible.
