We all know that drinking lots of water is essential, especially since this summer has been hella-hot. And while the reusable bottle movement is hardly new, these special-edition Fill. Drink. Repeat. bottles from Klean Kanteen give you even more incentive to switch over to an eco-friendly drink container you can use over an over again.

First of all, they happen to be designed by Shepard Fairey in partnership with SHFT.com; he’s the awesome contemporary artist behind the Obama “Hope” posters. Secondly, 10% of the proceeds from the sales of these bottles go to water.org, a non-profit organization, co-founded by Gary White and Matt Damon (yes, that Matt Damon) which works with developing communities throughout Asia, Africa and South America to create access to safe water and sanitation.

We’ve always loved the Klean Kanteen bottles which are made entirely from high-quality stainless steel with no BPA, no suspect lining and nothing that will make your water taste like anything besides water. Each bottle is $19.95, spread that over the cost of…um…forever and I’d say it’s a pretty good value.
