The Dopper Sport Cap turns the Dopper into a handy sports bottle, making it even more versatile in its usage. Sustainability and innovation are at their very best because you don’t even need a new bottle. Another reassuring, sustainable fact is the Dopper Sport Cap does not contain BPA or any other toxic plasticiser.
The cap should only be used for cold water and only in combination with the Dopper Originals and Steels.
