Fits the AYA & IDA Drinking Bottle The detail.. About the Designer... AYA&IDA is a Danish-owned family business, with the names AYA & IDA being two of the owners daughters. The thinking behind the brand is working to address the limitations that will exist for future generations if we continue our consumption carelessly. They believe that a more responsible lifestyle benefits everything and everyone. All that’s needed are the right products – and products made from natural materials can have long, functional lives and then return to where they came from, rather than accumulating in a landfill. The brand combines design, functionality and elegance in products that are all associated with a mission - to reduce excessive plastic waste, while making a difference for the people who do not have the same opportunities that exist in Denmark through the company’s charitable foundation. As consumers and creators, they believe that even the smallest changes can have a big impact, supporting a philosophy that the life cycle of a product should be circular rather than linear.
