Our Mission in Action
As a family and employee-owned company, we don't have to answer to stakeholders. We're free to operate based on our values every single day. We've built our business by prioritising the well being of people and the planet and by designing sustainable, high-performance products.
We designed our interchangeable caps to easily transition from coffee to water to smoothies and more, meaning you can buy fewer bottles.
We are 100% Carbon Neutral in the manufacture and delivery of our products worldwide.
We give 1% of every sale to help make the world a more sustainable place, donating over $3.4 million to date!
We're part of the B Corp movement to meet high standards of social and environmental transparency.
