We chose Liberty Bottleworks to make our water bottles for numerous reasons, foremost is that they are not only made in the US, they are made right here in Washington State. Liberty's principles and practices can't be beat.  Their 96% waste free facility in Union Gap, Washington uses only US sourced recycled aluminum cans and industrial scrap, and use recycled milk jugs for their caps. They carefully created a durable, flexible lining that is third party tested to be non-toxic and BPA and other estrogen active material free.
