Combine practical, good design with a cause to help others, and I’m sold and The Tumbler by MiiR is all those and then some. A simple, insulated tumbler for your coffee and tea that not only keeps your beverages hot, it supports a great cause to boot.

We all know incorporating reusable goods into our lives cuts down on the need for disposable paper products filling up the landfill. This project has an additional do-good angle though – for each Tumbler bought, one person gets clean drinking water for an entire year.

The Tumblers come with unique tracking codes to let you see which project you helped fund. Pretty cool, right?
